Instructions
Funfetti Cake
- Preheat the oven to 350F degrees. Then grease and flour a 9x13 inch baking pan.
- In a large bowl sift together the flour, baking powder, baking soda, and salt.
- In a separate large bowl beat the butter and sugar together until fluffy (about 2 minutes).
- Add in the vanilla extract, then beat in the eggs 1 at a time.
- With the mixer on low speed, beat in the sour cream followed by about 1/2 of the flour mixture. Turn off the mixer and scrape down the sides of the bowl as necessary.
- Then mix in the milk, followed by the rest of the flour mixture.
- Turn off the mixer and gently stir in the sprinkles using a large rubber spatula.
- Pour the batter into the prepared pan and bake for 25-30 minutes, or until an inserted toothpick comes out clean.
Vanilla Frosting
- In a large bowl beat the butter until fluffy.
- Beat in 3 cups of powdered sugar, starting with the mixer on low speed then gradually increasing the speed as it begins to incorporate.
- Then add in the salt. Mix in the rest of the powdered sugar about 1/2 cup at a time, alternating with a tablespoon or 2 of cream until the desired sweetness level is reached.
- Frost the cooled cake and decorate with sprinkles
Notes
*Room temperature ingredients preferred.
**Depending on how much frosting you like, there may be some leftover.
***Store leftovers in an airtight container at room temperature. Unfrosted cake can be wrapped tightly and frozen. Then thaw overnight in the fridge, and frost when ready to serve.
