Ingredients

Spider Cupcakes

  • 1 cup all-purpose flour
  • 1 cup granulated sugar
  • 1/2 cup unsweetened cocoa powder
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1/2 cup milk (or any plant milk)
  • 1/4 cup vegetable oil (or melted coconut/avocado oil)
  • 2 large eggs
  • 2 tsp vanilla extract
  • 1/2 cup boiling water

Classic Buttercream Frosting

  • 1 cup (2 sticks) unsalted butter, softened
  • 4 cups powdered sugar, sifted
  • 3 tbsp milk
  • pinch of salt

Instructions

1. Make the Spider Cupcakes

    1. Preheat oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.

    2. In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.

    3. Add milk, oil, eggs, and vanilla. Beat until smooth.

    4. Carefully mix in the boiling water — the batter will be thin, but that’s okay.

    5. Fill cupcake liners about 2/3 full. Sprinkle chocolate chips on top if using.

    6. Bake 22 minutes or until a toothpick inserted in the center comes out clean.

    7. Cool in pan 5 min, then transfer to a wire rack to cool completely before frosting.

 2. Make the buttercream frosting

  1. In a large bowl, beat butter with a hand or stand mixer on medium speed until creamy (2–3 minutes).
  2. Add powdered sugar gradually, 1 cup at a time, mixing on low speed until combined.
  3. Mix in a pinch of salt.
  4. Add milk, 1 tablespoon at a time, until the frosting is light and spreadable.
  5. Increase to high speed and whip for 2–3 minutes, until the frosting is fluffy and airy.

3. Serve Together

  1. Frost each cooled cupcake generously with buttercream.
  2. Using chocolate syrup, draw four lines across the frosting to create eight spider legs.
  3. Place half of an Oreo cookie on top to form the spider’s body.
  4. Add two candy eyes to the cookie to complete the spider design.
