A delightful twist on classic blondies, these bars are rich, nutty, and perfect for any occasion.
Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking pan.
Ensure the oven is fully preheated before placing the batter inside for even baking.
In a mixing bowl, beat the butter, brown sugar, and white sugar until creamy and smooth.
Use room temperature butter for easier mixing and a smoother texture.
Add the eggs, peanut butter, and vanilla extract to the mixture and beat until well combined.
Scrape down the sides of the bowl to ensure all ingredients are evenly mixed.
In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add this to the wet mixture, stirring until just combined.
Avoid overmixing to keep the batter light and fluffy.
Fold in the chopped peanuts to the batter.
Reserve some peanuts to sprinkle on top for added texture.
Spread the batter evenly into the prepared baking pan.
Use a spatula to smooth out the top for even baking.
Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Check the bars a few minutes before the end of the baking time to avoid overbaking.
Allow the bars to cool completely in the pan before cutting into squares.
Use a sharp knife for clean cuts and wipe it between slices.
