  • Total Time: 45 minutes
  • Yield: 9 servings

Ingredients

Cake:

  • 1½ cups flour
  • 1 cup sugar
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 5 tablespoons oil (such as vegetable oil or canola oil)
  • 1 tablespoon vinegar
  • 1 teaspoon vanilla
  • 1 cup water
  • ¼ cup sprinkles (use jimmies for best results)

Frosting:

  • ¼ cup (4 tablespoons) softened butter (substitute non-dairy butter if desired)
  • 2 cups powdered sugar
  • 12 tablespoons milk (substitute non-dairy milk if desired)
  • 1 teaspoon vanilla paste
  • Additional jimmies (sprinkles) for the top

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to ensure it reaches the perfect baking temperature for the cake.
  2. Combine Dry Ingredients: In an ungreased 8×8-inch baking pan, place the flour, sugar, baking soda, and salt. Stir them together using a fork to evenly combine all the dry ingredients.
  3. Add Wet Ingredients Separately: Make three small wells in the flour mixture. Pour the vanilla into one well, the vinegar into the second well, and the oil into the third well to keep them separated initially.
  4. Mix Batter: Pour the water evenly over the entire mixture, then use a fork to stir everything together, making sure to scrape the edges so no dry flour remains. Mix just until combined.
  5. Fold in Sprinkles: Gently stir in the ¼ cup of sprinkles to distribute them throughout the batter without overmixing.
  6. Bake the Cake: Place the baking pan in the preheated oven and bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean, indicating the cake is fully baked.
  7. Prepare Frosting: In a large bowl, combine the softened butter, powdered sugar, vanilla paste, and 1 to 2 tablespoons of milk. Use a hand mixer to beat the mixture until it is light and fluffy, creating a smooth frosting.
  8. Frost and Decorate: Once the cake has cooled completely, spread the vanilla frosting evenly over the top. Sprinkle additional jimmies (sprinkles) on top for a festive finish.

Notes

  • Use jimmies sprinkles rather than nonpareils to avoid bleeding colors in the batter.
  • The vinegar reacts with the baking soda to help the cake rise without eggs.
  • This cake is naturally dairy-free in the batter, but you can choose to use dairy or non-dairy butter and milk for the frosting based on preference.
  • Make sure the cake has completely cooled before frosting to prevent melting.
  • Store leftovers covered at room temperature for up to 3 days or refrigerate for up to a week.
