These Coffee Mug Sugar Cookies come from this Christmas Minis set, which includes 24 different classic Christmas designs. Check out the post to learn more about creating the full set!

For this set, we are doing a one consistency outline and flood with my “thick flood” consistency. This is the perfect consistency for a one consistency outline and flood because it’s thin enough that it will settle (with some help) and thick enough that it won’t fall straight off the cookie. Given that, if it’s the correct “thick flood” consistency, you’ll likely need a scribe to help settle the icing.

In the consistency instructions I do say to err on the thinner side if you’re unsure with the flood consistency (it’s usually better to have your flood be too thin than too thick). That said, if your flood is truly too thin then either a) cut the tip of your bag smaller to have more control over the icing/use less and/or b) do a two consistency outline and flood instead (outline with the soft peak piping consistency of the same color, allow it to dry for 10 minutes and then flood using the flood consistency).

I’m the kind of cookie decorator that is comfortable doing both a one and two consistency outline and flood, so I’ll choose one based on the needs of the set. I prefer to use a thick flood for minis because a) it simplifies things, b) it creates a more seamless and puffy look and c) you can still do wet on wet with a thick flood on such a small cookie. That said, it you really prefer doing a two consistency outline and flood, you can certainly do that with this set!

How to Make These Coffee Mug Sugar Cookies

I recommend breaking up the cookie decorating process into a several day affair. Decorating an entire set of cookies with royal icing from start to finish is not something you can accomplish in a few hours, and would be challenging (if not impossible for some) to complete in a full day of working.

Step 1: Purchase All Supplies, Ingredients, Tools etc Needed

Step 2: Bake the Cookies

I recommend baking the cookies up to 2 days before you plan to decorate. Store uniced cookies in an airtight container on the counter for up to 1 week before icing.

Check out my cookie recipe here.

Step 3: Prep the Icing for Decorating

Start this process up to 24-48 hours before decorating.

Check out my icing recipe here.

I recommend breaking up the icing prep into two days:

  1. Day before: make fresh icing, divide the icing into bowls labeled for each color, and do an initial phase of coloring the icing (keeping in mind that color develops/darkens over time–read here for more specifics on color development to prevent color bleed)
  2. Morning of (no more than a couple hours before decorating): final adjustments to color and thin the icing to desired consistencies

  • White – just white
    • Thick flood – err on the THINNER side if unsure
  • Brown – just chocolate brown
    • Thick flood – err on the THINNER side if unsure
  • Green – royal blue + lemon yellow
    • Soft peak piping consistency – err on the THICKER side if unsure

How to hold tipless bags:

  1. Line the SEAM up with your knuckles
  2. Line the top of the bag up with the top of your hand
  3. Hold the bag from the TOP with just your pointer and thumb
  4. Wrap the rest of your fingers around the bag

How to cut tipless bags (Check out this video starting at time stamp 7:03):

  1. Hold the bag with the SEAM up
  2. Squeeze the bag to gently fluff up the tip of the bag (do NOT squeeze the tip of the bag as that will create another fold)
  3. Cut STRAIGHT across with sharp scissors (any uneven cuts/jagged cuts can result in icing coming out of the bag in a squiggle as it snags the excess plastic along the way)
  4. Approximate amounts to cut:
    • Outline/piping consistency: 4-6mm
    • Flood: 5-7mm

Step-by-Step Decorating Instructions: Coffee Mug Sugar Cookies

Coffee Mug Sugar Cookies decorated with royal icing

***Since we’re working with mini cookies in this, you may want to cut the tips slightly small than what I’d normally recommend above (especially for the flood consistencies). The thinner your flood, the smaller you’ll want to cut the tip on your bag (because you’ll have more control over the icing). If your icing is too thick, you may want to cut the tip of your bag slightly bigger.

Step 1: Flood

Use white thick flood consistency to outline and flood the main part of the mug. Allow to dry for 10-15 minutes to allow the icing to crust.

Step-by-Step Decorating Instructions: Coffee Mug Sugar Cookies

Step 2a: Handle

Use white soft peak piping consistency to pressure pipe the handle. To do this, apply a significant amount of pressure on the bag to pipe a bit enough single line of icing for the handle of the mug.

If you prefer to do this a more “traditional” and avoid the pressure piping, you can always outline the handle with soft peak piping and flood with the thick flood (I would probably add a squiggle of icing inside the handle if there’s room to prevent craters).

Step-by-Step Decorating Instructions: Coffee Mug Sugar Cookies

Step 2b: Coffee

Use brown thick flood consistency to outline and flood the coffee (or hot chocolate??) portion of the mug. Allow to dry for at least 2 hours until the main part of the mug is basically completely dry, smooth to the touch and can withstand a small amount of pressure.

Step-by-Step Decorating Instructions: Coffee Mug Sugar Cookies

Step 3: Details

Use the black edible fine tip pen to write JOY on the mug. Make sure that your icing is basically completely dry because it’s very easy to poke a hole in the icing with the fine tip marker.

Then, use white medium peak piping consistency to pressure pipe the whipped cream on top. For this, you’ll want to apply significant pressure on the bag to get a thicker amount of icing out. Twirl it inward to create the swirl effect.

Then, use green soft peak piping consistency to pipe the pressure piped heart. To do this, you start by piping a dot. Then, you start to pull away from the dot towards the cookie AND you simultaneously release pressure to create the tear drop look. Do two of these in a V shape to create the heart.

These Coffee Mug Sugar Cookies are delicious and decorated with the best royal icing!

Instructions

Sugar Cookies:

  1. Preheat oven to 375 degrees F (190 C)
  2. In a large bowl, whisk together flour, corn starch and salt.
  3. In a medium bowl, measure out the sugar.
  4. In a small bowl, crack in the eggs.
  5. In a small bowl, measure out the vanilla bean paste.
  6. Using paddle attachment, cream together butter and sugar. Beat on medium high until mixture is well-incorporated and is slightly lighter in color. It should be airy and fluffy.
  7. Add in the eggs one at a time, just barely incorporating the mixture after each egg.
  8. Add in the vanilla. Mix on low first to incorporate until the mixture is viscous, then beat on medium high until the mixture is fluffy again. Do not over mix!
  9. Add in the flour mixture. Be careful not to over mix the dough. The dough is done when it starts to clumb on the paddle and pulls away from the sides.
  10. Roll dough out to 5/16", cut out shapes and plan on pan (I prefer to use perforated silicone baking mats).
  11. Bake for 8-12 minutes at 375 degrees F (bake time depends on size of cookies & how closely placed together)

Royal Icing:

Yields 35-37 ounces of icing.

1. Using a paddle attachment (or whisk if you prefer), beat meringue powder (45 grams) and 1/2 cup + 2 TBSP lemon juice on medium high (speed 6) until a beer-like foam forms (approx. 1-2 minutes). Scrape down the sides at least once. More detailed breakdown for the 1-2 minutes:

  • Beat on medium (speed 4) for 30 seconds
  • Scrape the bowl
  • Beat on medium high (speed 6) for 1 minute
  • At this point you have reached 1.5 minutes of beating. It is OK to beat for longer if needed! Almost impossible to over mix at this stage.

2. Add in the powdered sugar and mix on lowest speed until incorporated. Scrape down the sides.

3. Mix icing on medium speed for 2-4 minutes until a fluffy icing forms at either a stiff or medium peak, depending on yours needs (depending on your environment and desired consistency, you may need to add some or all of the additional 2 TBSP lemon juice). More detailed breakdown of the 2-4 minutes:

  • Stir on low for 30 seconds
  • Beat on medium (speed 4) for 30 seconds
  • Scrape the bowl
  • Beat on medium (speed 4) for 1 minute
  • Scrape the bowl - if you need more liquid, now is the best time to add any or all of the remaining 2 TBSP of lemon juice
  • Beat on medium (speed 4) for 30 seconds (either for one final spin or to incorporate the additional liquid)
  • At this point you have reached 2.5 minutes of mixing. If you added additional liquid, you may want to beat for another 30 seconds to more fully incorporate. If you need to continue to adjust liquid, you still have more time to beat the icing before it is over mixed. Icing should either be at a stiff peak piping consistency or medium peak piping consistency (if it's much stiffer than a fluffy stick peak, then add more water).

***All indicated speeds are for a KitchenAid stand mixer.

Prep the Icing for Decorating

Start this process up to 24-48 hours before decorating.

I recommend breaking up the icing prep into two days:

  1. Day before: make fresh icing, divide the icing into bowls labeled for each color, and do an initial phase of coloring the icing (keeping in mind that color develops/darkens over time--read here for more specifics on color development to prevent color bleed)
  2. Morning of (no more than a couple hours before decorating): final adjustments to color and thin the icing to desired consistencies

Colors & consistencies that you'll need for this set:

Click here for a post on how to figure out how much royal icing you need.

To achieve these muted/dulled colors, make sure you add a small amount (start with a pea size or smaller) amount of each color to each color (except for the white). This will a unified color harmony and will take away any brightness from the colors as you'll be adding colors from the opposite side of the color wheel to each other. Just make sure not to add too much! Start with a small amount and go from there.

For this set, we are doing a one consistency outline and flood with my “thick flood” consistency. This is the perfect consistency for a one consistency outline and flood because it’s thin enough that it will settle (with some help) and thick enough that it won’t fall straight off the cookie.

  • Thick flood - err on the THINNER side if unsure

Grey - lesser saturation of black

  • Soft peak piping consistency - err on the THICKER side if unsure

  • Soft peak piping consistency - err on the THICKER side if unsure
  • Thick flood - err on the THINNER side if unsure

Red - red + tiniest bit of royal blue

  • Thick flood - err on the THINNER side if unsure

Blue - royal blue + tiniest bit of black (use a toothpick)

  • Soft peak piping consistency - err on the THICKER side if unsure
  • Thick flood - err on the THINNER side if unsure

    Notes

    Cookie Baking Notes:

    • Use an oven thermometer: It wasn't until just a few years ago that I learned that not all ovens heat to the temperature on the dial. In fact, most of them don't! That's why I always use an oven thermometer and recommend that everyone do! If you want to go next level you can even put one in the front and one in the back as sometimes these temps can vary.
    • Cream together the butter and sugar enough: You want to make sure you've incorporated enough air into the butter and sugar. This is indicated by the mixture turning a slightly lighter color and appearing fluffy.
    • Don't over work your dough: you'll want to mix the dough at the final stage JUST ENOUGH. It will be done when the dough sticks to the paddle/comes off the sides of the bowl. You ALSO do not want to over work your dough as you're rolling it out. It is for this reason many cookiers only roll out twice. I personally roll as many times as I have dough, but I make sure to barely incorporate the scraps of dough (I let the rolling pin do all the work).
    • Roll your dough to a consistent thickness: by rolling your dough to a consistent thickness, you'll make it much easier to bake your cookies evenly. I roll my dough to 5/16".
    • Use powdered sugar instead of flour to roll your dough: if you're like me and use every bit of your dough, I recommend using powdered sugar instead of flour to roll your dough. When I use flour it adds too much flour to the dough and makes it drier.
    • Roll out your dough on parchment paper: I always roll out my dough on parchment paper, which makes transferring the cookies to the pan a dream (I peel the dough off the parchment paper before transferring to the pan)! I like to use these precut parchment paper sheets.
    • Bake with perforated baking mats: I find that perforated baking mats give the most even bake because air is allowed to flow under the cookie. Baking with perforated baking mats can take some getting used to. Make sure you read the instructions on the product website. For example, do NOT use a scented soap to clean them and make sure ALL of the soap is cleaned off (because of the perforations soap can get caught and make your cookies taste like soap). Alternatively, you can use standard silicone baking mats or parchment paper.
    • Don't over bake your cookies: every recipe is different, but I've found with my recipe that the cookies are done when they are JUST set on the edges and cooked through the center. A tiny bit of golden brown is usually ok, but any more and they're overcooked.
    • Flatten the cookies with a spatula after baking: this can get out an bubbles that formed while baking AND gives you a little extra peace of mind that the surfaces are actually flat 🙂

    Royal Icing Notes:

    I recommend 1 batch of icing per 1 batch of cookie dough (you'll have extra icing, but it's better than running out).

    Be careful not to over mix, as that can cause air bubbles or ruin the icing (it will crumble when dry). Watch the mixer carefully in this last stage as the mixing time can vary greatly. I always recommend setting a timer once you have added all of the ingredients to the bowl to avoid over-mixing (once you reach 5 minutes+ you risk over-mixing).

    This recipe makes about 35-37 ounces of icing. A standard 3.5" cookie typically requires 1-1.25 ounces icing/cookie. Of course this depends on the design! I like to budget 1.5 ounces icing/cookie just to be safe. So this recipe makes enough icing for 24 (2 dozen) cookies.
