• Preheat oven to 350F (175C) and line baking sheets with parchment paper. Set aside.
• In a large mixing bowl, use an electric mixer to cream butter and sugars together until creamy and well combined.
  1 cup (226 g) unsalted butter, 1 cup (200 g) granulated sugar, ¾ cup (150 g) light brown sugar
• Add egg, egg yolk, and vanilla extract and stir until combined.
  1 large egg + 1 large egg yolk, 1 teaspoon vanilla extract
• In a separate, medium-sized bowl whisk together flour, cocoa powder, baking powder, baking soda, and salt.
  2 ¼ cups (280 g) all-purpose flour, ½ cup (50 g) natural cocoa powder, 1 teaspoon baking powder, ¼ teaspoon baking soda, ¾ teaspoon salt
• Gradually add dry ingredients to wet ingredients, stirring until completely combined.
• Scoop cookie dough by 2 Tablespoon-sized scoops and roll between your palms to make a smooth ball. Place on baking sheet, spacing cookies at least 2” (5cm) apart and bake in 350F (175C) oven for 10-11 minutes.
• Within one minute of removing cookies from the oven, gently flatten the surface of the cookie using a 1-cup measuring cup (this will give you a smooth surface for decorating the cookie). While cookies are cooling, prepare your frosting.

For the frosting

• Combine cream cheese and butter in a large mixing bowl and use an electric mixer to beat until smooth and creamy.
  6 oz (170 g) cream cheese, 6 Tablespoons (85 g) unsalted butter
• Add vanilla extract and salt, stir until combined.
  ¾ teaspoon vanilla extract, ⅛ teaspoon salt
• With mixer on low speed, gradually add powdered sugar until completely combined.
  2 ⅔ cups (333 g) powdered sugar
• Add cocoa powder and stir until completely incorporated and frosting is uniform.
  ½ cup (50 g) natural cocoa powder

Assembly

• Spread or pipe frosting onto cooled cookies (I like to use a piping bag fitted with an open tip to pipe the frosting then smooth it with an offset spatula).
• Sprinkle cookie crumbs evenly over the frosting then gently nestle 1-2 gummy worms on top of the frosting. Enjoy!
