Ingredients

Scale

Macaron Shells

  • 105 g Sifted Super Fine Almond Flour
  • 105 g Sifted Confectioners Sugar
  • 100 g Egg Whites
  • 100 g White Sugar
  • 3 g (1 tsp) Egg White Powder (meringue powder, optional but highly recommended)
  • 1 tsp Artificial Vanilla
  • Nonpareils Rainbow Sprinkles

Birthday Cake Buttercream Filling

  • 1 cup (130 g) White or Yellow Boxed Cake Mix
  • 1 cup (227 g) Unsalted Butter, at room temperature
  • 3 cups (360 g) Confectioners Sugar
  • 2 tbsp (28 g) Heavy Cream
  • 1 tsp Artificial Vanilla
  • Pink Food Colouring

Instructions

  1. Prepare Dry Ingredients: Sift the almond flour until you have 105 grams, discarding any large pieces. Repeat with the confectioners sugar. Whisk both together very well and set aside.
  2. Prep Baking Sheets: Line one or two baking sheets with parchment paper or silicone baking mats.
  3. Make the Meringue: In a stand mixer bowl, combine the egg whites, white sugar, and egg white powder. Place this bowl over a simmering pot of water (a bain-marie), making sure the bowl does not touch the water. Whisk continuously while heating until the mixture reaches 140°F (60°C). Remove from heat.
  4. Whip the Meringue: Attach the bowl to your stand mixer fitted with the whip attachment. Start beating on low speed until soft peaks form, then increase to medium speed until medium peaks form. Finally, beat on high speed until stiff peaks form. Add vanilla and mix until just combined.
  5. Combine Dry Ingredients with Meringue (Macaronage): Sift the almond flour and confectioners sugar mixture into the meringue bowl using a sieve. Fold gently using a circular motion and then cutting through center, similar to drawing the Greek letter phi (Φ). Be gentle to not overmix. The batter should flow off the spatula in continuous ribbons and pass the figure 8 test.
  6. Pipe the Macarons: Transfer the batter to a piping bag fitted with a medium round tip. Pipe small 1½ inch diameter circles onto the lined baking sheets, holding the bag perpendicular. Tap the tray multiple times on the counter to remove air bubbles. Use a toothpick to pop any remaining bubbles. Sprinkle rainbow nonpareils on top.
  7. Dry the Macarons: Let the macarons sit at room temperature to form a skin. This typically takes from 8 minutes up to an hour. They are ready when you can lightly touch them without batter sticking to your finger.
  8. Bake the Macarons: Preheat the oven to 300°F (275°F for convection). Bake macarons for 15-20 minutes, checking at 15 minutes. They are done when the tops are firm and do not move on their base.
  9. Cool and Pair: Allow macarons to cool completely before removing them from the liners. Match the shells into pairs of similar size.
  10. Prepare Birthday Cake Buttercream: Microwave the boxed cake mix in a microwave-safe bowl for about 1 minute and 30 seconds, stirring every 30 seconds, until heated through to 170°F. Let it cool for 10 minutes.
  11. Make Buttercream: Beat butter on medium-high with a stand mixer until light and fluffy (about 3 minutes). Gradually add cooled cake mix and confectioners sugar in intervals until smooth and well combined. Add heavy cream, vanilla, and pink food coloring. Mix until fully incorporated. Transfer to a piping bag with a star tip.
  12. Assemble Macarons: Pipe the birthday cake buttercream onto the bottom halves of the macaron pairs, then sandwich with the tops. Place assembled macarons in the fridge overnight to mature, allowing flavors to meld and texture to develop.

Notes

  • Egg white powder is optional but helps stabilize the meringue and improves macaronage.
  • forming a skin on macarons before baking is crucial for developing the characteristic feet.
  • Use a stencil or macaron mat for consistent piped sizes and shapes.
  • Overmixing the batter will deflate the meringue and ruin the texture; rely on ribbon and figure 8 tests to gauge readiness.
  • Letting macarons mature in the fridge overnight improves flavor and texture.
  • Temperature of the oven may vary; watch closely during baking and adjust time accordingly.
  • Butter should be at room temperature for the best buttercream texture.
