Step‑by‑Step Instructions for Birthday Cake Macarons
Step 1: Prep Dry Ingredients
Begin by sifting together the superfine almond flour and confectioners sugar in a bowl; this ensures a smooth macaron shell. Use a fine-mesh sieve and tap the sides gently to eliminate any lumps. Once combined, set aside your dry mixture while you focus on whipping up the meringue.
Step 2: Make Meringue
In a heatproof bowl placed over a saucepan of simmering water (bain-marie), combine egg whites, granulated sugar, and egg white powder. Warm this mixture gently to 140°F (60°C) while stirring continuously. Once heated, transfer to a mixer and whip on high speed until stiff peaks form, and the meringue appears glossy and holds its shape.
Step 3: Macaronage
Gently fold the sifted dry ingredients into the meringue using a spatula, being careful not to deflate the mixture. Incorporate them until the batter flows smoothly like lava and can form a figure-eight without breaking. This step, known as macaronage, is crucial for achieving the right consistency in your Birthday Cake Macarons.
Step 4: Pipe Macarons
Transfer the macaron batter into a piping bag and pipe 1½-inch circles onto a parchment-lined baking sheet. Maintain an even spacing between the circles to allow room for spreading. Once piped, sprinkle rainbow sprinkles generously on top of each macaron to add a festive touch!
Step 5: Dry
Let the piped macarons sit at room temperature for 8 minutes to 1 hour, depending on humidity, until they form a skin. You’ll know they’re ready when the tops are dry to the touch and do not stick to your finger. This drying process is essential for achieving that perfect macaron texture.
Step 6: Bake
Preheat your oven to 300°F (or 275°F for convection). Bake the macarons for 15-20 minutes, keeping an eye on them as oven times may vary. They should rise slightly and develop a firm shell but remain soft inside. Let them cool slightly on the tray before transferring them to a wire rack.
Step 7: Cool Completely
After baking, allow the Birthday Cake Macarons to cool fully on the wire rack. This cooling step is crucial for preventing any sogginess and ensuring they retain their beautiful shape. Once cool, gently lift them off the parchment, being careful to maintain their intact shells.
Step 8: Make Buttercream
To prepare the filling, heat-treat the boxed cake mix in the microwave for 1-2 minutes until it reaches 160°F (71°C); allow it to cool completely afterwards. In a mixing bowl, beat the unsalted butter until fluffy, then gradually mix in the cooled cake mix and confectioners sugar. Add the heavy cream and a few drops of pink food coloring, blending until smooth and creamy.
Step 9: Assemble Macarons
Pipe a generous dollop of the birthday cake buttercream filling onto the flat side of half the macaron shells. Top each with the remaining shells, pressing gently to sandwich the filling. To let the flavors meld together and enhance the texture, refrigerate the assembled macarons for at least 30 minutes before serving.

What should I do if my macaron shells crack during baking?
Very good question! Cracking is usually a sign that there was too much moisture or not enough drying time.
