Ingredients

Scale

Brownie Base

  • 1 cup brown sugar
  • 1 cup sugar
  • 2 tsp vanilla extract
  • 1/2 tsp salt
  • 2 whole eggs
  • 2 egg yolks
  • 8 oz semi-sweet chocolate chips (melted)
  • 1/2 cup butter
  • 1/2 cup vegetable oil
  • 1 1/4 cup all-purpose flour
  • 1/4 cup cocoa powder
  • 12 Mint Oreos

Ganache Topping

  • 12 oz white chocolate chips
  • 3/4 cup heavy cream
  • Green food coloring
  • Red and heart sprinkles

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and line a 9×13 inch baking dish with parchment paper for easy removal.
  2. Mix Sugar and Eggs: In a large bowl, combine brown sugar, granulated sugar, vanilla extract, salt, whole eggs, and egg yolks. Whisk until the mixture is smooth and slightly fluffy.
  3. Melt Chocolate and Butter: Using a double boiler, melt the semi-sweet chocolate chips together with the butter, whisking until fully combined and smooth.
  4. Add Oil to Chocolate Mixture: Whisk the vegetable oil into the melted chocolate and butter mixture until incorporated.
  5. Combine Mixtures: Pour the chocolate mixture into the sugar and egg mixture. Stir together until fully combined.
  6. Fold in Dry Ingredients: Gently fold in the all-purpose flour and cocoa powder, being careful not to overmix to keep the brownies tender.
  7. Prepare for Baking: Pour the brownie batter evenly into the prepared baking pan. Place the 12 Mint Oreos evenly spaced on top of the batter and gently press them down so they become partially engulfed.
  8. Bake Brownies: Bake in the preheated oven for 35 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs but no raw batter.
  9. Prepare Ganache: Place the white chocolate chips in a heat-proof medium bowl. Heat the heavy cream on the stovetop over medium heat until it just starts to simmer; do not boil.
  10. Make Ganache: Pour the hot cream over the white chocolate chips and let sit for three minutes. Stir gently until smooth and creamy. Add green food coloring a few drops at a time and stir thoroughly until you achieve the desired vivid green color.
  11. Apply Ganache: Pour the green ganache over the cooled brownies and use a knife or spatula to spread it evenly across the surface.
  12. Add Sprinkles: Sprinkle red and heart-shaped sprinkles generously over the ganache, ensuring each brownie piece will have decoration when sliced.
  13. Set and Serve: Allow the brownies to rest for at least one hour at room temperature so the ganache can set completely. Carefully lift the brownies using the parchment paper and cut into squares as desired before serving.

Notes

  • Ensure the butter and chocolate are fully melted but not overheated to maintain a smooth consistency.
  • Press the Oreos lightly into the batter so they don’t sink entirely but integrate into the brownies.
  • Allow the brownies to cool completely before adding ganache for best results.
  • You can adjust the intensity of the green food coloring to your preferred shade.
  • Store leftover brownies in an airtight container at room temperature for up to 3 days or refrigerated for up to a week.
