Peanut butter chocolate bars are ultra-thick, chewy, sticky and filled with tons of sweet, chocolate-flavored peanut butter.
Ingredients
1 stick (113 grams) of unsalted butter
1 3/4 (350 gram) cups light brown sugar
1/2 cup (135 grams) soft peanut butter
2 eggs plus one egg yolk
1 teaspoon vanilla extract
2 1/4 cups (286 grams) all-purpose flour
1 teaspoon baking powder
1/4 teaspoon baking soda
1/2 teaspoon salt
6 ounces (170 grams) of semi-sweet chocolate chips
Directions
Preheat the oven to 350°F. Line an 8-inch by 8-inch metal baking sheet with parchment or aluminum foil.
In a saucepan over medium heat, melt the butter. Add brown sugar, stirring until smooth. Remove from heat and add peanut butter. Allow cooling.
In a large mixing bowl, combine the flour, baking powder, baking soda and salt.
Once the butter mixture cools, add the eggs and yolk, one by one, until well combined. Add the vanilla extract. Pour the mixture into the prepared dry ingredients, and stir to create a very thick dough. Fold 3/4 of the chocolate pieces, reserving the rest to sprinkle on top.
Transfer the dough to the prepared tray, spreading it evenly to the edges. Sprinkle with the remaining chocolate chunks, pressing them lightly into the dough.
Bake for 30 minutes, or until top is golden and edges are lightly browned. Allow to cool in the pan. Use the parchment to remove the bars before cutting them into squares and serving. Store in an airtight container at room temperature for up to 3 days.
