Ingredients & Supplies

Prep Time: 30 Minutes
Bake Time: 35-40 Minutes
Yields: 8 dirt cups

  • 1/2 teaspoon ARM & HAMMER™ Baking Soda
  • 3/4 cup unsweetened cocoa powder
  • 2/3 cup vegetable oil, divided
  • 1/2 cup boiling water
  • 2 cups white sugar
  • 2 eggs
  • 1 1/3 cups all-purpose flour
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • 8 clear cups
  • Quart-size zip-top bag
  • Green food coloring
  • Toppings: chocolate pudding, chocolate chips, coconut flakes, gummy worms, crushed up crème-filled chocolate cookies


  1. Preheat oven to 350°F to make your brownie base.
  2. In a large bowl, stir together cocoa powder and ARM & HAMMER™ Baking Soda. Add 1/3 cup vegetable oil and boiling water. Mix well.
  3. Stir in sugar, eggs, and another 1/3 cup vegetable oil.
  4. Add flour, vanilla extract and salt; mix well. Use non-stick spray on a 9” x 13” pan. Pour into pan and bake for about 35 minutes, or until a toothpick inserted comes out clean. Allow to cool before using.
  5. While that bakes, it’s time to make the grassy surface. Spoon coconut flakes into a zip-top bag, add 6 drops of green food coloring. Seal the bag, then shake and knead to evenly distribute color into the coconut. Set aside.
  6. Let the kids arrange all ingredients in layers (aka, your time to kick back). Bedrock layer: chocolate chips. Subsoil layer: crumbled brownie and pudding. Topsoil layer: crushed crème-filled sandwich cookies. Final layer: green-colored coconut flakes and gummy worms.
