  • 1/4 cup oat milk
  • 1 teaspoon white distilled vinegar
  • 3/4 cup all-purpose flour
  • 3/4 teaspoon baking powder
  • 1/4 teaspoon kosher salt
  • 1/4 cup plus one tablespoon Country Crock® Plant Butter with Avocado Oil Stick room temperature
  • 1/4 cup plus 3 tablespoons granulated sugar
  • 1 teaspoon pure vanilla extract
  • 1/8 teaspoon almond extract
  • 1 large egg white, room temperature
  • 3 tablespoons rainbow sprinkles (we recommend only the long sprinkles that contain corn starch and not nonpareil sprinkles as those tend to bleed in the batter)
  • 6 tablespoons Country Crock® Plant Butter with Avocado Oil Stick, room temperature
  • 1 3/4 cups confectioners' sugar, sifted
  • 1 1/2 teaspoons pure vanilla extract
  • 2 to 3 tablespoons oat milk

  1. Preheat the oven to 325°F and line a muffin tin with 6 cupcake liners.
  2. Combine the oat milk and vinegar in a small cup and set aside.
  3. In a medium mixing bowl, sift together flour, baking powder, and salt. Set aside.
  4. In a large mixing bowl with an electric mixer or the bowl of a stand mixer, cream the Country Crock Plant Butter and sugar together until fluffy, about 2 minutes. Scrape down the sides.
  5. With the mixer on low, add the vanilla extract, almond extract, and egg white, and mix until just combined, scraping down the sides as needed.
  6. With the mixer on low, add the dry ingredients in two parts, alternating with the oat milk, scraping down the sides as needed and mixing until just combined (do not overmix - a few lumps are okay).
  7. Add the rainbow sprinkles and gently fold in with a rubber spatula.
  8. Divide the batter between the six cupcake liners and bake on the middle rack for 32-35 minutes, until the center springs back when poked and a toothpick comes out clean or with just a few crumbs. Transfer to a wire rack to cool completely before frosting.
  9. In the bowl of a stand mixer or a large mixing bowl with an electric mixer, cream the Plant Butter until smooth. With the mixer on low, slowly add the powdered sugar, mixing until combined. Add the vanilla and a tablespoon of oat milk at a time, mixing until smooth and spreadable. Fold in a few drops of gel food coloring, as desired.
  10. Using a large star piping tip, pipe the frosting onto the cooled cupcakes and top with more sprinkles.
