Ingredients:
Batter
1 cup unsifted bleached all-purpose flour
1/4 teaspoon baking soda
1/8 teaspoon salt
2 large eggs
2/3 cup plus 1 tablespoon firmly packed light brown sugar
5 tablespoons granulated sugar
10 tablespoons (1 stick plus 2 tablespoons) unsalted butter, melted and cooled to warm
3 tablespoons smooth (creamy) peanut butter
2 teaspoons vanilla extract
1 1/4 cup milk chocolate-covered peanut butter cup chunks
2/3 cup lightly salted roasted and skinned peanuts
1/3 cup semisweet chocolate chips
1 cup unsifted bleached all-purpose flour
1/4 teaspoon baking soda
1/8 teaspoon salt
2 large eggs
2/3 cup plus 1 tablespoon firmly packed light brown sugar
5 tablespoons granulated sugar
10 tablespoons (1 stick plus 2 tablespoons) unsalted butter, melted and cooled to warm
3 tablespoons smooth (creamy) peanut butter
2 teaspoons vanilla extract
1 1/4 cup milk chocolate-covered peanut butter cup chunks
2/3 cup lightly salted roasted and skinned peanuts
1/3 cup semisweet chocolate chips
Directions:
Preheat the oven to 350 degrees F.
Film the inside of a fluted 8 1/2 to 9-inch false-bottomed tart pan (2 inches deep) with softened unsalted butter.
For the batter, sift the flour, baking soda, and salt onto a sheet of waxed paper.
Whisk the eggs in a medium-size mixing bowl to blend. Add the light brown sugar and whisk for 45 seconds. Add the granulated sugar and whisk just to combine, about 30 seconds. Blend in the melted butter, peanut butter, and vanilla extract. Resift the flour mixture over the butter and sugar mixture. Whisk slowly to form a batter, scraping down the sides of the mixing bowl with a rubber spatula to keep the batter even-textured. Stir in the chunks of peanut butter cups, the peanuts, and chocolate chips. The batter will be fairly thick and heavy.
Scrape the batter into the prepared pan. Smooth the top with a flexible palette knife.
Bake the sweet in the preheated oven for 30 to 35 minutes, or until just set. The top will puff slightly, then retreat a little on cooling. The top will be golden in between the nubbins of chocolate chips, candy chunks, and peanuts.
Avoid over baking or the cake will be dry
instead of moist. Cool the sweet in the pan on a cooling rack for 20
minutes. Carefully lift the cake by the bottom, pushing it up and out to
unmold, and remove the fluted ring. Cool completely. Cut the cake into pie-shape wedges and remove from the pan, using a small offset metal spatula. Store in an airtight tin.
