• 份量: 16 bars

食材

1 cup (128g) all purpose flour, sifted (plus 1 teaspoon for the chocolate chips)

2 tablespoons (20g) cornstarch

1 teaspoon baking powder

1/4 teaspoon fine sea salt

1/4 cup (57g) unsalted butter, room temperature

1/2 cup (128g) creamy peanut butter

3/4 cup (150g) packed brown sugar

1/4 cup (50g) granulated sugar

2 large eggs, room temperature

1 1/2 teaspoons pure vanilla extract

1 cup (170g) semisweet chocolate chips

1/2 cup (71g) semisweet chocolate, chopped

2 tablespoons (28g) unsalted butter

1 teaspoon light corn syrup

步驟

Preheat the oven to 350ºF (180ºC). Line the bottom of an 8-inch square baking pan with parchment paper. Grease and flour the insides.

In a medium-size bowl, whisk together the flour, cornstarch, baking powder, and salt until well combined.

In a large bowl, beat the butter and peanut butter together, with an electric mixer, until smooth and well blended. Add the brown sugar and granulated sugar. Beat until combined. Beat in the eggs and vanilla extract in 3 separate additions, making sure each one is incorporated before adding the next. Stir in the flour mixture just until combined.

In a small bowl, toss the chocolate chips with 1 teaspoon of flour then fold them into the batter. Transfer the batter to the baking pan. Smooth the top with a spatula. Bake until the top is golden brown and a toothpick inserted into the center of the bars comes out with a few moist crumbs on it, about 20-25 minutes. Let cool in the pan. Spread the chocolate glaze over the cooled bars.

Combine the glaze ingredients in a heat-safe bowl set over a pan of gently simmering water, making sure the water doesn't touch the bottom of the bowl. Stir occasionally until melted and smooth.
