Ingredients

Scale

For the Brownies:

  • 1 cup sugar
  • 1/2 cup vegetable oil
  • 3 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1/2 cup cocoa powder
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt

For the Cookie Dough Layer:

  • 1 cup unsalted butter, softened
  • 1 1/2 cups brown sugar, packed
  • 2 cups all-purpose flour (heat-treated for safety)
  • 2 tablespoons milk
  • 1 1/2 teaspoons vanilla extract
  • 1 cup mini chocolate chips

For the Ganache:

  • 1 cup semi-sweet chocolate chips
  • 1/2 cup heavy cream

Instructions

  1. Prepare the Brownies:

    • Preheat oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment.
    • In a large bowl, whisk sugar and oil until smooth. Add eggs and vanilla, mixing until well combined.
    • In a separate bowl, combine flour, cocoa powder, baking powder, and salt. Gradually add dry ingredients to the wet ingredients, stirring until just combined.
    • Divide batter evenly among prepared pans and bake for 20-25 minutes, or until a toothpick inserted comes out with moist crumbs. Let cool completely.
  2. Make the Cookie Dough:

    • In a large mixing bowl, beat butter and brown sugar until light and fluffy. Mix in vanilla.
    • Gradually add heat-treated flour, mixing until fully incorporated, then add milk until dough is smooth.
    • Stir in mini chocolate chips.
  3. Prepare the Ganache:

    • In a microwave-safe bowl, heat the heavy cream until steaming (about 45 seconds).
    • Pour cream over chocolate chips in a separate bowl. Let sit for 1 minute, then stir until smooth and glossy.
  4. Assemble the Cake:

    • Place one brownie layer on a serving plate. Spread half of the cookie dough over the brownie.
    • Top with a second brownie layer, followed by the remaining cookie dough.
    • Place the final brownie layer on top. Pour ganache over the cake, allowing it to drip down the sides.
    • Refrigerate for at least 30 minutes to set.
  5. Serve and Garnish:

    • Before serving, add extra mini chocolate chips or a drizzle of ganache on top for garnish.

Notes

  • Safety Tip: Heat-treat flour before using to eliminate any bacteria (bake at 350°F for 5-10 minutes).
  • Storage: Store any leftovers in an airtight container in the refrigerator for up to 5 days.
  • Make Ahead: You can make the brownies a day in advance to save time.
