Why This Dinosaur Birthday Cake Stands Out

Recipe: How to Make the Dinosaur Birthday Cake
Prep Time: 20 minutes | Cook Time: 30 minutes | Total Time: 1 hour 50 minutes | Servings: 12
Ingredients
- See above for full ingredient list.
Instructions
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
- In a medium bowl, whisk together flour, baking powder, and salt.
- In a large bowl, beat butter and sugar until light and fluffy, about 3 minutes.
- Add eggs one at a time, beating well after each addition. Stir in vanilla.
- Gradually add the flour mixture to the butter mixture, alternating with milk, beginning and ending with flour. Mix until just combined.
- Divide batter evenly between prepared pans. Bake for 28-32 minutes, or until a toothpick inserted in the center comes out clean.
- Cool cakes in pans for 10 minutes, then turn out onto a wire rack to cool completely.
- For the frosting, beat butter until creamy. Gradually add powdered sugar, milk, and vanilla, beating until smooth. Tint with green and a touch of brown food coloring to create a muddy green shade.
- Place one cake layer on a serving plate. Spread a thin layer of frosting on top. Add the second layer and frost the entire cake.
- Press crushed chocolate cookies onto the sides of the cake for a dirt effect. Top with green sprinkles and arrange dinosaur toys on top.
Tips
- For a chocolate version, replace ½ cup flour with ½ cup cocoa powder.
- Use a serrated knife to level cake layers for a professional look.
- If using fondant dinosaurs, make them a day ahead and let them dry.
