You’ll need basic baking ingredients like butter, sugar, flour, eggs, vanilla extract, and baking soda. Plus, peanut butter cups (chopped), peanut butter, and chocolate chips for the gooey filling.
Prepare a rich cookie dough by mixing together butter, sugar, eggs, flour, and baking soda. This dough will form the bottom and top layers of the bars.
For the gooey middle, melt together peanut butter and chocolate chips, or you can use a creamy peanut butter filling to spread between the cookie dough layers.
Cut your peanut butter cups into small pieces to fold into the cookie dough or sprinkle over the bars for added texture and flavor.
Spread half of the cookie dough in the bottom of the baking pan, then layer with the melted peanut butter chocolate mixture, and finally top with the remaining cookie dough.
Bake the bars in a preheated oven, typically around 350°F (175°C), for about 25-30 minutes until golden and set but still slightly gooey in the center.
Let the bars cool completely before cutting into squares. Enjoy the perfect balance of chewy, gooey, and chocolatey goodness!
