This Funfetti Wacky Cake has all the fun and none of the dairy! With no milk, eggs, or butter, this cake uses a minimum of ingredients with maximum flavor! If you don't want to use the butter for buttercream, this cake would also be delicious with just a dusting of powdered sugar!
Preheat oven to 350° F. Grease an 8" x 8" pan and set aside.
In a large bowl, combine the dry ingredients (flour, sugar, baking powder, baking soda, and salt). Add the water, oil, vinegar, and vanilla bean paste (see note). Mix until just combined. Fold in sprinkles.
Pour batter into prepared pan and bake 30-35 minutes, or until a toothpick inserted in the center comes out with just a few crumbs attached. Place on a wire rack to cool completely.
For Buttercream (see note):
Cream the butter and sugar in the bowl of a stand mixer until smooth. Add vanilla bean paste (see note) and mix to combine. Add milk or water one teaspoon at a time until you reach the desired consistency.
Frost the cooled cake with the buttercream, topping with more sprinkles, if desired.Enjoy!
Notes
Note on vanilla bean paste: The vanilla is the only flavor to this cake and the buttercream, so I went for the added flavor punch of using vanilla bean paste. Plus you know it's my fave ingredient. If you're looking to get some for yourself, you can find it [here]. You can also substitute an equal measure of vanilla extract.Note on buttercream: If you don't want to use butter for the buttercream, the cake is still delicious with just a dusting of powdered sugar!
