These birthday cake macarons are a delightful addition to any celebration. Light and airy, they’re filled with cake-batter buttercream and finished with colorful rainbow sprinkles for a playful, festive touch.
It’s almost my birthday, and that means I’m craving cake, sprinkles, and something sweet. While I also enjoy savory dishes, for my birthday I always want dessert—lots of it. These macarons capture full birthday-cake flavor without the work of baking and decorating a whole cake.
Macarons may seem intimidating, but this French-style version is approachable and can be made in roughly an hour. The shells are meringue-based, naturally gluten free, and are sandwiched with a cake-batter buttercream that’s studded with white cake mix for an unmistakable cake flavor. If you need the finished sandwich to be gluten free, swap the frosting for a gluten-free filling since most store-bought cake mixes contain gluten.
Ingredients for birthday cake macarons
For macarons:
- Almond flour – the base of the shells; find it at most grocery or health-food stores.
- Powdered sugar – sifted and mixed with the almond flour for a fine texture and sweetness.
- Egg whites – ensure no yolk is present so the meringue whips properly.
- Cream of tartar – stabilizes the meringue for better structure.
- Granulated sugar – to sweeten and stabilize the meringue during whipping.
- Teal gel food coloring – gives the shells their bright color without adding liquid.
- Sprinkles – optional, for a celebratory finish on the white shells.
For cake-batter buttercream:
- Unsalted butter – softened, the fat base for a creamy frosting.
- Vanilla extract – adds depth and warmth to the filling.
- Powdered sugar – sweetens and thickens the buttercream.
- White cake mix – a small amount folded into the buttercream gives that cake-batter flavor.
- Heavy cream – loosens and lightens the frosting to a spreadable, whipped consistency.
- Pink gel food coloring – optional, for a soft pink buttercream or any color you prefer.
Making birthday cake macarons — step-by-step
Step one:
Wipe the bowl of your mixer with a bit of vinegar or lemon juice and dry it thoroughly. This removes any grease that could prevent the egg whites from whipping properly.
Step two:
Weigh your ingredients and have everything ready before you begin. Accurate measurements are crucial—this recipe uses grams for the macaron components.
Step three:
Whisk together the almond flour and powdered sugar until well combined and set aside.
Step four:
In the mixer bowl, combine egg whites and cream of tartar and begin whipping until bubbly. Gradually add granulated sugar on medium speed, then increase speed and whip until stiff, glossy peaks form.
Step five:
Fold half of the almond flour mixture into the meringue, working around the bowl and folding through the center until there are no dry spots.
Step six:
Add the rest of the dry ingredients and fold until combined, stopping before the mixture reaches the “molten lava” overmixed stage. See the notes below for how to recognize the correct consistency.
Step seven:
Divide the batter in half. Tint one half with teal gel food coloring and leave the other half white. Fold each gently until both reach the molten-lava consistency.
Step eight:
Fit a large round piping tip into a piping bag. Pipe 1½-inch circles of batter onto a silicone baking mat or parchment, alternating colors as desired. Tap the baking sheet to release air bubbles.
Step nine:
Add sprinkles to the white shells, then let the piped shells rest for 30–45 minutes, until they form a dry “skin” that doesn’t stick when touched.
Step ten:
Preheat the oven to 295°F (about 145°C). Bake the shells for 15–16 minutes. They’re done when the tops are firm and the shells don’t wobble on their feet.
Step eleven:
Let the shells cool completely on the baking sheet before removing them to avoid cracking or sticking.
Step twelve:
Make the cake-batter buttercream: beat softened butter until smooth, add vanilla, powdered sugar and white cake mix, then finish with heavy cream until light and fluffy. Tint with pink gel coloring if desired.
Step thirteen:
Pipe a dollop of buttercream onto a teal shell, sandwich with a white shell, and repeat until all cookies are assembled.
Step fourteen:
Macarons improve after maturing: refrigerate assembled macarons for at least 24 hours for the best texture and flavor. Bring to room temperature before serving.
Equipment needed
Basic tools make macarons easier: a kitchen scale, stand or hand mixer, baking sheets, silicone mats or parchment, piping bags, and a round piping tip. A macaron-specific silicone mat with guides helps keep cookie sizes consistent.
Macaron vs. macaroon
Macarons are delicate, sandwich-style French cookies made from almond flour, egg whites, and sugar. They have a crisp exterior and chewy interior and are typically filled with buttercream, ganache, curd, or jam. Macaroons are denser coconut-based cookies and are a different treat entirely.
French vs. Italian macaron methods
The French method whips uncooked egg whites with sugar and folds in the almond mixture and is generally simpler. The Italian method involves making a hot sugar syrup that is poured into whipped egg whites for a more stable meringue—favored in bakery settings for its reliability.
Tips for folding macaron batter
Folding is the most technical part. Stop folding once the batter reaches the “molten lava” stage: it should move slowly and steadily when you pull a spatula through. Test by drawing a figure 8 with the batter—if it flows without breaking, it’s ready.
Storing
Store assembled macarons in an airtight container in the refrigerator for up to three days. For best flavor and texture, allow them to come to room temperature before serving.
Freezing
You can freeze unfilled macaron shells for up to one month. Place them in a single layer on parchment in an airtight container; thaw for about an hour before filling.
Why use gel food coloring
Gel food coloring is more pigmented and contains less liquid than regular food coloring, so it won’t affect batter consistency. For vibrant colors with minimal impact on texture, choose gel-based colors and add sparingly until you reach the shade you want.
