If you shouldn’t judge a book by its cover, maybe you also shouldn’t judge cakes by their icing. Especially this one. By only looking at it, you might think it’s a plain vanilla cake. Though this gluten-free recipe contains classic ingredients, sprinkles added to the batter make it a lot more fun than a traditional cake. Whether you’re celebrating at a birthday party or surprising someone you love, serve them this extraordinary dessert.

1 pkg. (19 oz.) Bob’s Red Mill Gluten-Free Vanilla Cake Mix
1/2 cup gluten-free sprinkles or jimmies
1 tsp. vanilla extract
1/2 cup oil
1/2 cup water
1/4 tsp. almond extract, optional
3 eggs


6-3/4 cups powdered sugar
1/4 tsp. almond extract
2-1/4 cups butter, softened
1 tsp. vanilla extract
4 – 6 Tbsp. milk or cream, if needed
Sprinkles, for decorating


  1. Preheat oven to 325 degrees F. Spray two 9-inch cake pans with cooking spray and line bottom of pan with parchment paper.
  2. In the bow of a stand mixer or in a large bowl with a hand mixer, beat eggs on medium-low for 30 seconds. Add cake mix, vanilla extract, oil, water and almond extract and beat for an extra minute. Add sprinkles and mix until well distributed in batter.
  3. Transfer batter evenly to cake pans and smooth tops with a spatula. Bake for 30-40 minutes or until a toothpick comes out clean.
  4. Meanwhile, prepare frosting. In a large bowl with hand mixer, mix powdered sugar and butter for 1 minute on low, then increase speed to medium and mix for about 5 minutes or until light and fluffy. Add vanilla extract, almond extract and milk or cream if needed and mix for another minute.
  5. When cake is done baking, let cool for 15 minutes in pans before transferring to separate plates to fully cool. Once cool, you can begin frosting.
  6. If desired, cut cakes in half to make 4-layer cake. Frost each layer and stack on top of each other. Frost outside of cake and decorate as desired.
