How to Make These Heart 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

Click here for a list of all basic baking/cookie decorating supplies

Keep in mind that some of these products are sourced from small businesses (especially the cookie cutters), and maybe take up to a couple of weeks to arrive.

Cookie cutters:

Curvy heart (3.5″)
- Amazon alternative
Geometric heart (3.25″ by Sweet Sugarbelle – discontinued)
- Alternative by Bobbi’s Cutters

Food Coloring:

Click here for links to basic sets of gel food coloring colors from Wilton, Chefmaster, Americolor and Artisan Accents (search “gel colors” in post).

White:
Orange: the orange in this set is slightly more on the yellow side and is made mixing pink and yellow for a “softer” orange. Either mix from scratch with yellow + pink, or use orange straight from the bottle for a perfectly acceptable but slightly different orange (you can also add a little yellow to the bottle orange).

- Pink: Wilton Pink //OR// Chefmaster Baker’s Rose //OR// The Sugar Art Hot Pink
- Orange: Chefmaster //OR// Americolor //OR// Wilton

Color Palette

Tools + decorations you’ll need for this set:

Scissors (small and sharp)
Toothpick or scribe
Paper towels
Tool for crackle technique (rounded end) – or just anything with a rounded end like a paintbrush, scribe, pen, etc.
Edible glitter (The Sugar Art DiamonDust in White Diamond)

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:

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)
Morning of (no more than a couple hours before decorating): final adjustments to color and thin the icing to desired consistencies

How to hold tipless bags:

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

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

Hold the bag with the SEAM up
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)
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)
Approximate amounts to cut:
- Outline/piping consistency: 4-6mm
- Flood: 5-7mm

Step-by-Step Decorating Instructions: Heart Cookies

Step 1a: outline + flood

Use orange thick flood consistency to outline and flood the cookie (use a scribe if needed to help settle the icing.

Check out this post for a detailed explanation of how long it takes for royal icing to dry and what you can do at different stages.

step 1 of decorating heart cookies with royal icing

Step 1a: edible glitter

IMMEDIATELY spray the wet icing with edible glitter (this step is optional if you’d prefer to skip it).

Allow the icing to dry for 10-20 minutes until it is ready for crackle stage (if your icing is indenting instead of cracking, it just needs a little bit longer to dry).

step 2 of decorating heart cookies with royal icing

Step 3: crackle

Use a tool with rounded end to apply the crackle technique to the entire surface of the cookie. A few things to keep in mind:

You want to CRACK the surface not puncture it. If your too had icing on the tip after using, then you’ve punctured the surface instead of cracking.
If your cracks are more like indents, the icing just need a little bit longer to dry.
Don’t crackle too close to the edge (leave a couple of millimeters). If you crackle too close to the edge, you will inevitably ruin the end of the icing. If this happens, just use your finger to nudge it back into place!
The cracks should join each other, not look like separate polka dots.
I usually prefer the look of more random cracks than being methodical and doing one row at a time, for example.

Instructions

Sugar Cookies:

Preheat oven to 375 degrees F (190 C)
In a large bowl, whisk together flour, corn starch and salt.
In a medium bowl, measure out the sugar.
In a small bowl, crack in the eggs.
In a small bowl, measure out the vanilla bean paste.
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.
Add in the eggs one at a time, just barely incorporating the mixture after each egg.
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!
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.
Roll dough out to 5/16", cut out shapes and plan on pan (I prefer to use perforated silicone baking mats).
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.

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

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.
