👩‍🍳 Instructions

Step 1: Bake the Cake Layers

Preheat oven to 350°F (175°C). Grease and flour two 8-inch round cake pans. In a bowl, whisk flour, baking powder, and salt. In a separate bowl, beat butter and sugar until fluffy. Add eggs one at a time, then vanilla. Mix in dry ingredients alternately with milk. Divide batter into pans and bake 25–30 minutes. Cool completely.

Step 2: Make the Buttercream

Beat butter until creamy. Gradually add powdered sugar, vanilla, and milk until smooth. Tint with green gel food coloring until you get the Ninja Turtle green you like.

Step 3: Frost the Cake

Level cake layers if needed. Spread frosting between layers, stack, then crumb coat. Chill 20 minutes. Apply final layer of green buttercream, smoothing with spatula.

Step 4: Make Fondant Faces

Roll out green fondant and cut into circles for turtle heads. Use colored fondant for each bandana (red, orange, blue, purple). Add white fondant eyes and black pupils. Attach to cake sides with a dab of frosting.

Step 5: Decorate & Serve

Add pizza slice fondant toppers or piped “Happy Birthday” on top. Chill until serving.

🧊 Leftovers & Storage

Bring to room temp before serving for best texture.
Fondant decorations keep best in a cool, dry place.
