Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish and line it with parchment paper, leaving overhang on the sides for easy removal.
In a large mixing bowl, cream together the butter, granulated sugar, and brown sugar until light and fluffy, about 2-3 minutes.
Add the peanut butter and mix until fully incorporated. Then mix in the eggs and vanilla extract until smooth.
In a separate bowl, whisk together the flour, quick oats, baking powder, and salt.
Gradually add the dry ingredients to the wet ingredients and mix until just combined. Avoid overmixing.
Spread the dough evenly into the prepared baking dish using a spatula or your hands.
Bake in the preheated oven for 20 minutes, or until the edges are golden and the center is set. Avoid overbaking for softer bars. Let the bars cool completely in the pan.
Once the bars are cool, gently heat the additional peanut butter in the microwave in 20-second intervals until smooth and spreadable. Spread it evenly over the bars.
Melt the chocolate chips in a microwave-safe bowl in 30-second intervals, stirring after each to prevent burning. Spread the melted chocolate over the peanut butter layer.
Let the chocolate set completely at room temperature or in the refrigerator before slicing into bars. Use the parchment paper to lift the bars out of the pan for easy cutting.
Serve and enjoy these rich and nostalgic peanut butter bars!
