Ingredients
Method
- Beat butter, oil, and sugar until fluffy, about 3 minutes. Add eggs one at a time, then vanilla. Whisk flour, baking powder, baking soda, and salt separately. Add dry mixture alternately with buttermilk, starting and ending with dry. Fold in sprinkles.
- Preheat oven to 350°F (175°C). Grease two 8-inch round pans, line with parchment. Divide batter, smooth tops. Bake 25-30 minutes until a toothpick comes out clean. Cool 10 minutes in pans, then turn out onto a rack to cool completely.
- For the buttercream, beat butter until creamy. Gradually add powdered sugar, then milk and vanilla. Beat until fluffy. Tint as desired.
- Level cakes if needed. Spread filling between layers, then apply a thin crumb coat with green frosting. Chill 15 minutes.
- Spread a final green coat. Pipe or smear animal prints with brown, yellow, and dark brown frosting. Decorate with toy animals and a candle.
Notes
If the frosting feels too soft during decorating, pop the cake back in the fridge for 10 minutes. For a neater finish, use an offset spatula dipped in hot water and wiped dry to smooth the final coat. The cake is easiest to slice when it’s at cool room temperature.
