directions

Preheat the oven to 350°F (175°C) and line a cupcake pan with paper liners.

In a small bowl, mix plant-based milk with apple cider vinegar or lemon juice to create a vegan “buttermilk.” Let sit for 5 minutes.

In a large mixing bowl, whisk together flour, baking powder, salt, and sugar.

Add the vegan buttermilk, oil, and vanilla extract to the dry ingredients. Stir until just combined.

Divide the batter evenly into six bowls and mix each with a different food coloring to create rainbow colors.

Layer each colored batter into the cupcake liners in rainbow order (starting with purple or red on the bottom).

Bake for 18–22 minutes, or until a toothpick inserted comes out clean. Let cool completely.

For the frosting, beat vegan butter until creamy, then gradually add powdered sugar and vanilla. Add a small splash of milk if needed for texture.

Frost the cooled cupcakes and decorate with sprinkles, edible gold dust, or mini marshmallows to resemble clouds.
