Prep and Cook Time
Prep: 45 minutes | Cook: 30 minutes | Chill: 2 hours
Yield
Serves 10-12 slices
Difficulty Level
Medium – perfect for home bakers ready to impress with layered techniques and textural contrasts
Ingredients
- 1 ¾ cups (230g) cake flour, sifted
- 1 ¼ cups (250g) granulated sugar
- 1 tsp baking powder
- ½ tsp baking soda
- ½ tsp kosher salt
- 1 cup (240ml) buttermilk, room temperature
- ¾ cup (170g) unsalted butter, softened
- 3 large eggs, room temperature
- 2 tsp vanilla extract
- ½ cup rainbow sprinkles (jimmies recommended for best texture)
- For the frosting:
- ½ cup unsalted butter, softened
- 1 ½ cups powdered sugar, sifted
- 1 tbsp milk
- 1 ½ tsp vanilla extract
- Pinch of salt
- Optional: Extra sprinkles for garnish
- For the crunch layer:
- 1 cup crushed cornflakes
- 3 tbsp granulated sugar
- 2 tbsp melted unsalted butter
- ¼ tsp salt
Instructions
- Preheat the oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment paper. This ensures a clean release and perfect shape.
- Prepare the Birthday Cake Crumb: In a large mixing bowl, sift together cake flour, granulated sugar, baking powder, baking soda, and salt. In a separate bowl, whisk buttermilk, softened butter, eggs, and vanilla extract until fully combined.
- Slowly add the wet ingredients into the dry mixture,stirring gently to prevent overmixing (which can toughen the crumb). Fold in the rainbow sprinkles just before transferring the batter evenly into the prepared pans.
- Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Avoid opening the oven door early to prevent collapse. Let the cakes cool in the pans for 10 minutes, then turn out onto wire racks to cool entirely.
- While the cake cools, prepare the confetti crunch: In a bowl, combine crushed cornflakes, sugar, melted butter, and salt, spreading the mixture evenly on a parchment-lined baking sheet. Bake at 350°F (175°C) for 10 minutes until crunchy and lightly golden. Let cool.
- Make the frosting: Using a hand mixer, beat softened butter, powdered sugar, milk, vanilla extract, and salt until soft and creamy. Adjust milk quantity to achieve a smooth spreading consistency.
- Assemble the cake: Level the cooled cake layers with a serrated knife for even stacking. On your serving plate, place one layer of cake, spread a generous layer of frosting, then sprinkle a hearty layer of crunch. Repeat with the second cake layer and finish with frosting on top and sides.
- Chill the assembled cake for at least 2 hours before serving.This step lets the frosting set and the crunch meld beautifully with the moist crumb.
- Just before serving,garnish with extra rainbow sprinkles for that iconic Milk Bar look and joyful pop of color.
Tips for Success
- For the most authentic Birthday Cake flavor, use jimmie-style sprinkles rather than nonpareils-nonpareils can bleed color and alter texture.
- If buttermilk isn’t on hand, make your own by adding 1 tbsp lemon juice or vinegar to 1 cup milk and letting it sit for 5 minutes.
- Don’t skip pressing the crumb firmly when assembling to achieve the balanced texture Milk Bar’s cake is known for.
- Make the crunch up to two days ahead and store in an airtight container for fresh crunchiness.
- To keep your frosting beautifully smooth,beat the butter until completely softened but not melted.
Perfect Pairings and Serving Tips
This cake pairs exquisitely with a tall glass of classic vanilla milkshake-both iconic birthday treats in one sitting. For an adult twist,serve alongside a lightly chilled sparkling rosé or prosecco,whose bubbles cut through the buttercream richness elegantly.
For presentation, slice with a clean sharp serrated knife dipped briefly in hot water to ensure those rainbow sprinkles stay intact, revealing the layered magic inside. Add a few fresh berries or edible flowers to the serving platter for an extra festive flourish.
