Chewy chocolate cookies, velvety chocolate buttercream, finely crushed Oreos and fruity gummy worms make these Dirt Cookie Cups a Halloween sensation! They’re super easy to make and fun to decorate.


For the Chocolate Cookie Cups

  • 3/4 cup (168g) unsalted butter, room temperature
  • 1 cup (207g) sugar
  • 1 large egg
  • 1 tsp vanilla extract
  • 1 1/4 cups (163g) all purpose flour
  • 1/2 cup (57g) natural unsweetened cocoa powder
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 2 tsp cornstarch

For the Chocolate Buttercream

  • 1/2 cup (112g) unsalted butter, room temperature
  • 1 3/4 cups (201g) powdered sugar
  • 1/4 cup (29g) natural unsweetened cocoa powder
  • 1/2 tsp vanilla extract
  • 24 tbsp (30-60ml) heavy whipping cream (or water)
  • 1/8 tsp salt

For the Toppings

  • 8 Oreos
  • 34 gummy worms


  1. Spray cupcake pan with non-stick cooking spray. Preheat oven to 350 degrees.
  2. Cream butter and sugar together for 3-4 minutes, until light in color and fluffy in texture.
  3. Add the egg and vanilla and beat until well combined.
  4. Add the dry ingredients to the wet ingredients and mix just until well combined. Dough will be a little sticky.
  5. Make balls of about 2 tablespoons of cookie dough. Press cookie dough into the bottom and about 1/2 way up the sides of each cupcake cup, forming a cup shape.
  6. Bake for 10-12 minutes.
  7. Remove from oven and allow to cool for about 5 minutes. The centers should fall a bit while cooling, but if the centers aren’t cupped enough to add filling, use the underside of a measuring tablespoon to press the center down a bit.
  8. Remove to cooling rack to finish cooling.
  9. When the cookie cups are cool, make the buttercream. Add the butter to a large mixer bowl and beat until smooth and creamy.
  10. Add about half of the powdered sugar and mix until smooth and well combined.
  11. Add the cocoa powder and mix until well combined and smooth.
  12. Add the vanilla extract and 2 tablespoons of water or cream and mix until smooth and well combined.
  13. Add the remaining powdered sugar and mix until smooth and well combined.
  14. Add more water or cream until desired consistency is reached, then add salt. Set aside.
  15. Add the Oreos to a food processor (leave the filling in the Oreo) and grind into crumbs. Set aside.
  16. Place one gummy worm into each cookie cup.
  17. Fill the centers of the cookie cups with chocolate buttercream, leaving the head of the worm inside sticking out. I prefer using a piping bag so that it’s quick, easy and looks clean.
  18. Sprinkle Oreo crumbs over the buttercream, covering it completely, then add another worm on top.
  19. Store cookie cups in an airtight container. They are best eaten within 2-3 days.
