# Step-by-Step Guide:

01 - Preheat oven to 350°F (175°C). Grease and line two 8-inch (20 cm) round cake pans with parchment paper.
02 - In a bowl, whisk together flour, baking powder, and salt.
03 - In a large bowl, cream butter and sugar until light and fluffy. Beat in eggs one at a time, then add vanilla.
04 - Alternately fold in the flour mixture and milk in three additions, beginning and ending with flour. Gently fold in the sprinkles.
05 - Divide batter evenly between pans. Bake for 28–32 minutes, or until a toothpick inserted comes out clean. Cool in pans for 10 minutes, then transfer to a wire rack to cool completely.
06 - Beat cream cheese and butter together until smooth. Gradually blend in powdered sugar. Add vanilla, milk, and sprinkles. Mix until creamy and light. Chill until ready to use.
07 - Place one cake layer on a platter. Spread a thick layer of funfetti dip on top. Add the second cake layer. Frost the top and sides with more funfetti dip.
08 - Decorate generously with sprinkles and spring candies. Chill at least 30 minutes before slicing.
