Tips for Success

Use room-temperature butter, eggs, and milk for a smooth batter.
Cream the butter and sugar thoroughly until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Do not overmix the batter after adding the flour.
Sift the powdered sugar for an extra-smooth icing.
Allow the cake to cool completely before frosting.
Adjust the icing consistency with additional milk or powdered sugar if needed.
Add the sprinkles immediately after spreading the icing so they adhere well.
Store the cake tightly covered to keep it moist.
For the cleanest slices, chill the cake for 15–20 minutes before cutting.

Instructions

Step 1: Prepare the Cake

Preheat the oven to 350°F (175°C).
Grease and line a 9 × 13-inch (23 × 33 cm) baking pan with parchment paper.
In a medium bowl, whisk together the flour, baking powder, and salt.
In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy, about 3–4 minutes.
Add the eggs one at a time, beating well after each addition.
Mix in the vanilla extract.
Alternately add the dry ingredients and the milk, beginning and ending with the dry ingredients. Mix just until combined.
Spread the batter evenly into the prepared baking pan.
Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool completely.

Step 2: Prepare the Vanilla Icing

In a medium bowl, whisk together the powdered sugar, milk or heavy cream, and vanilla extract until smooth.
Adjust the consistency as needed by adding a little more milk or powdered sugar.

Step 3: Decorate

Spread the icing evenly over the cooled cake.
Immediately sprinkle the rainbow sprinkles evenly across the top.
Allow the icing to set before slicing into squares.
