Ingredients
Brownies
- ½ cup butter room temperature
- ¼ cup neutral-flavored oil such as canola or avocado
- 5 ounces dark chocolate chips about ¾ cup
- 1 cups granulated sugar
- 2 teaspoons vanilla extract
- 3 large eggs
- 1 cup all-purpose flour
- ¼ cup cocoa powder
- ¼ teaspoon baking powder
- ½ teaspoon salt
- 1 cup roasted salted peanuts optional
Frosting
- ½ cup natural peanut butter
- 2 tablespoons salted butter room temperature
- ½ cup powdered sugar
- 1 teaspoon vanilla extract
- 1-2 tablespoon whole milk
Ganache
- 5 ounces dark chocolate
- ½ cup heavy cream
Instructions
- Preheat your oven to 350 degrees Fahrenheit. Line a 9x9 inch square baking pan with parchment paper and grease it with butter. Place the butter and chocolate in a mixing bowl and microwave for 1 minute. Stir the chocolate until it's melted and smooth. Add the sugar, oil, and vanilla to the chocolate and whisk to combine. Add the eggs and whisk again.
- In a medium-sized bowl, whisk the flour, cocoa powder, salt, and baking powder. Mix the dry ingredients with the wet ingredients. If using, fold the peanuts into the batter.
- Pour the batter into the baking dish and smooth the top. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
- When the brownies are mostly cool, make the frosting. Use electric beaters to beat the peanut butter, butter, powdered sugar, and vanilla. Add 1 tablespoon of the milk and beat again. If you'd like a thinner frosting, add the second tablespoon. Spread the frosting over the brownies in the pan.
- To make the chocolate topping, add the chocolate and cream to a medium-sized bowl and microwave for 1 minute. Stir until the chocolate is melted and smooth then pour it over the brownies. (Make sure that it's not hot when you pour it over!) Set the brownies aside for at least 30 minutes for the chocolate to set. Sprinkle a little sea salt over top then cut the brownies into 16 pieces.
