Description

Chocolate brownies loaded with chocolate and peanut butter chips have gobs of creamy peanut butter swirled into the batter, surely making them a contender for best-ever brownies.

Ingredients

6 (1 ounce) squares unsweetened baking chocolate, coarsely chopped
1/2 cup unsalted butter
2 (1 ounce) squares semisweet baking chocolate, coarsely chopped
1 3/4 cups white sugar
3 large eggs
2 teaspoons vanilla extract
1 cup all-purpose flour
3 tablespoons all-purpose flour
1 cup dark chocolate chips
1 cup peanut butter chips
4 tablespoons peanut butter

Directions

1 Preheat the oven to 350 degrees F (175 degrees C). Line an 8-inch square baking pan with parchment paper.
2 Place unsweetened chocolate, butter, and semisweet chocolate in the top of a double boiler over simmering water. Stir frequently, scraping down the sides with a rubber spatula to avoid scorching, until chocolate is melted, about 5 minutes. Remove from the heat and cool to room temperature, about 10 minutes.
3 Whisk sugar, eggs, and vanilla extract together in a large bowl. Whisk in cooled chocolate mixture. Stir in flour with a spoon until incorporated. Stir in dark chocolate chips and peanut butter chips.
4 Spread 1/2 of the batter in the prepared baking pan. Take 1/2 of the peanut butter and put it in small dots over top of the batter, then use a knife to spread it into a marble-like pattern. Top with remaining batter, dot with remaining peanut butter, and swirl again.
5 Bake in the preheated oven until a toothpick inserted into the center comes out clean, 25 to 35 minutes. Let cool completely before slicing.
