Step-by-Step Frankenstein Cookies Recipe

1. Make the Macaron Shells

Line two baking sheets with parchment paper.
Sift powdered sugar and almond flour together into a bowl.
In another bowl, beat egg whites until foamy. Gradually add granulated sugar and beat until stiff, glossy peaks form.
Add green gel food coloring and gently fold in the almond flour mixture until smooth and flows like lava (the batter should slowly drip off a spatula).
Pipe small circles onto baking sheets. Tap trays on the counter to release air bubbles.
Let them sit for 30–60 minutes until the tops are dry to the touch.
Bake at 300°F (150°C) for 15–17 minutes. Allow to cool completely before filling.

2. Make the Filling

Beat butter until creamy.
Add powdered sugar, vanilla, and cream/milk. Mix until smooth and fluffy.
Pipe onto half of the cooled macaron shells, then sandwich with the other half.

3. Decorate Frankenstein Faces

Use black decorating gel or melted chocolate to add hair, stitches, and mouths.
Stick candy eyes on with a dab of icing.
Let set before serving.

Tips for Success

Use gel food coloring instead of liquid so it doesn’t thin your macaron batter.
Resting the shells before baking is essential to avoid cracks.
If you’re short on time, you can also decorate store-bought macarons or sandwich cookies instead of making them from scratch.

These Frankenstein Cookies are a spooktacular way to celebrate Halloween. They’re bright, fun, and guaranteed to impress both kids and adults. Whether you bake your macarons from scratch or decorate ready-made cookies, these little green monsters will be the hit of your Halloween spread.

So grab your piping bag, whip up some buttercream, and bring Frankenstein to life – in the sweetest way possible.
