Method
Step-by-Step
- Heat the oven to 350°F (175°C) and grease a 13 x 9-inch baking pan.
- Cream the softened butter, granulated sugar, and packed light brown sugar until light and fluffy.
- Beat in the eggs one at a time, then mix in the creamy peanut butter and vanilla extract until smooth.
- In a separate bowl, whisk together the all-purpose flour, baking powder, and salt.
- Gradually add the dry ingredients to the peanut butter mixture, mixing only until combined.
- Spread the thick batter evenly in the prepared pan.
- Bake for 25–30 minutes, until the edges are lightly golden and a toothpick inserted near the center shows moist crumbs rather than wet batter.
- Cool for at least 20–30 minutes before slicing; the brownies become firmer and chewier as they cool.
Notes
Use regular creamy peanut butter rather than separated natural-style peanut butter for the most consistent batter. Do not overbake; a toothpick with a few moist crumbs is the best sign that the brownies are ready.
