1. Precisely weigh and sift the almond flour and powdered sugar together at least twice.

2. In a clean bowl, whisk egg whites and cream of tartar until foamy, then gradually add granulated sugar and beat on high until stiff, glossy peaks form.

3. Gently fold the dry ingredients into the meringue in three parts until the batter flows like slow-moving lava.

4. Divide the batter if using multiple colors, gently fold in gel food coloring, and transfer to a piping bag with a small round tip.

5. On a lined baking sheet, pipe a circle for the head and two elongated ovals for ears, then tap the sheet firmly to release air bubbles.

6. Let the piped macarons rest at room temperature for 30-60 minutes, until a dry skin forms.

7. Preheat the oven to 300-325°F (150-163°C) and bake for 12-15 minutes until the shells are firm.

8. Let the macaron shells cool completely on the baking sheet before removing.

9. Prepare your desired filling, such as vanilla buttercream or white chocolate ganache.

10. Pipe filling onto the flat side of one macaron shell and sandwich with another.

11. Decorate the bunny faces using an edible ink pen and add pink luster dust to the ears if desired.
