Instructions

Let’s bring this colorful masterpiece to life:

Preheat Your Equipment:

Preheat your oven to 350°F (175°C). Proper preheating ensures even baking and a golden crumb topping.

Prepare the Crumb Topping:

In a small bowl, whisk together flour, sugar, baking powder, and salt. Stir in vanilla extract, melted butter, and sprinkles until combined. Set aside—the topping is ready to go on top of your cake batter.

Make the Cake Batter:

In a medium bowl, whisk together flour, sugar, baking powder, baking soda, and salt. In a separate bowl, cream the softened butter and egg until smooth. Add sour cream, milk, and vanilla extract, mixing until fully incorporated. Gradually fold in the dry ingredients until just combined—don’t overmix. Gently fold in rainbow sprinkles.

Prepare Your Baking Pan:

Grease your baking pan or line with parchment paper for easy removal. Proper preparation prevents sticking and ensures clean edges.

Assemble the Cake:

Pour the cake batter into the prepared pan, smoothing the top with a spatula. Evenly sprinkle the funfetti crumb topping over the batter. Press lightly if needed to help it adhere.

Cook to Perfection:

Bake for 40–45 minutes or until a toothpick inserted into the center comes out clean. The cake should be golden and the crumb topping slightly crisp.

Finishing Touches:

Let the cake cool in the pan for 10–15 minutes, then transfer to a wire rack to cool completely. This step ensures the topping sets without falling apart.

Serve and Enjoy:

Slice into squares or rectangles and serve! Each piece is a delightful combination of soft, buttery cake and crunchy, sweet topping—perfect for breakfast, brunch, or dessert.
