Ingredients
Brownie Batter
- 1 cup (220g) unsalted butter, melted
- 2 tbsp vegetable oil
- 1/2 cup (50g) unsweetened cocoa powder
- 1/2 tsp salt
- 2 cups (265g) all purpose flour
- 1 cup (200g) granulated sugar
- 1 cup (200g) dark brown sugar, packed
- 4 large eggs, room temperature
- 1 tbsp vanilla extract
Chocolate Frosting
- 1/4 cup (55g) unsalted butter, softened
- Pinch of salt
- 1/4 cup (25g) unsweetened cocoa powder
- 2 1/2 cups (270g) powdered sugar
- 1/4 cup (55g) milk
- 1 tsp vanilla extract
- Rainbow sprinkles, as desired
Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C) and grease either a 10×15 inch jelly roll pan or a 9×13 inch baking pan to prevent sticking.
- Mix Butter, Oil, and Cocoa: In a large bowl, whisk together the melted butter, vegetable oil, and unsweetened cocoa powder until fully combined and smooth.
- Add Dry Ingredients: Stir in the salt, all-purpose flour, granulated sugar, and dark brown sugar until evenly mixed into the cocoa butter mixture.
- Incorporate Eggs and Vanilla: Whisk in the room temperature eggs and vanilla extract to create a luscious, consistent batter.
- Prepare for Baking: Pour the prepared batter into the greased pan and spread it evenly for uniform baking.
- Bake the Brownies: Bake in the preheated oven for 15-20 minutes if using the jelly roll pan or 25-30 minutes for the 9×13 inch pan. The brownies are done when the surface looks matte and bubbly, and the center feels bouncy to the touch.
- Prepare Frosting: Immediately after removing the brownies from the oven, prepare the frosting by mixing softened butter, a pinch of salt, and cocoa powder in a bowl using a hand or stand mixer with a paddle attachment.
- Add Powdered Sugar and Liquids: Gradually add powdered sugar, one cup at a time, then mix in the milk and vanilla extract until smooth and creamy.
- Frost Brownies: Spread the warm chocolate frosting evenly over the brownies and finish by sprinkling rainbow sprinkles on top to add a fun, colorful touch.
- Cool and Serve: Let the brownies cool completely to set the frosting before slicing into 24 servings and enjoying your delightful treat.
Notes
- Using room temperature eggs helps the batter combine more smoothly.
- You can substitute milk with any plant-based milk to make the recipe dairy-free.
- Adjust baking times depending on your oven and pan thickness; watch for the matte and bouncy texture as your doneness indicator.
- For extra fudginess, slightly underbake the brownies and allow them to finish setting as they cool.
- Store brownies in an airtight container at room temperature for up to 4 days or refrigerate for up to a week.
