Ingredients
- 1 cup Unsalted Butter (melted)
- 1 cup Granulated White Sugar
- 1 cup Brown Sugar (packed)
- 2 tsp Vanilla Extract
- 4 large Eggs
- 1.25 cup All-Purpose Flour
- 1 cup Unsweetened Cocoa Powder
- 1 tsp Salt
- 1 tsp Baking Powder
- 2 tbsp Cornstarch
- 0.5 cup Whole Milk
- 8 oz Semi‑Sweet Chocolate Chips
- 4 oz Milk Chocolate Chips
- 1 cup Heavy Cream
- 0.5 cup Mini M&M's (Chocolate Sprinkles) (or any chocolate sprinkles)
Instructions
Cream Butter and Sugars
In a large mixing bowl, combine melted butter, granulated sugar, brown sugar, and vanilla extract. Using a hand mixer (or whisk), beat on medium speed until the mixture is light, fluffy, and pale in color, about 2 minutes.
Time: PT2M
Incorporate Eggs
Add the eggs one at a time, mixing well after each addition before adding the next.
Time: PT1M
Mix Dry Ingredients
In a separate bowl, whisk together all‑purpose flour, unsweetened cocoa powder, salt, baking powder, and cornstarch until fully combined and free of lumps.
Time: PT1M
Combine First Half of Wet and Dry
Add half of the dry ingredient mixture to the butter‑sugar mixture, followed by half of the milk. Mix on low speed until just incorporated; the batter will look slightly thick.
Time: PT2M
Finish the Batter
Add the remaining dry ingredients and the remaining milk. Stir until the batter comes together into a thick but spreadable consistency.
Time: PT2M
Prepare Pan and Transfer Batter
Line a 13×9‑inch baking pan with aluminum foil, allowing excess foil to hang over the sides for easy removal. Pour the batter into the pan and spread evenly with a spatula.
Time: PT1M
Bake Brownies
Place the pan in a pre‑heated oven and bake at 350°F for 18–20 minutes. Test with a toothpick inserted into the center; it should come out with a few moist crumbs but no wet batter.
Time: PT20M
Temperature: 350°F
Cool in Pan
Allow the brownies to cool in the pan for about 10 minutes before handling the ganache.
Time: PT10M
Prepare Chocolate Ganache
In a microwave‑safe bowl, combine the semi‑sweet chocolate chips, milk chocolate chips, and heavy cream. Microwave on high for 60–90 seconds, stopping to stir every 20 seconds, until the chocolate is fully melted and the mixture is smooth.
Time: PT2M
Spread Ganache Over Brownies
Using a spatula, spread the warm ganache evenly over the cooled brownies.
Time: PT1M
Add Sprinkles
Scatter mini M&M's (or chocolate sprinkles) over the ganache for a colorful crunch.
Time: PT0.5M
Set and Serve
Let the brownies sit for about 5 minutes to allow the ganache to set, then lift out using the foil and cut into 12 squares.
Time: PT5M
