Preheat the oven to 350°F (175°C) and grease a 9x9-inch baking pan.
In a mixing bowl, cream together the peanut butter and softened margarine until smooth. Add the white sugar, brown sugar, eggs, and vanilla, then mix until the batter becomes light and fluffy.
In a separate bowl, combine the flour, baking powder, and salt.
Add the dry ingredients to the peanut butter mixture and stir until a smooth batter forms.
Spread the batter evenly into the prepared pan and sprinkle peanuts on top if desired.
Bake for 30–35 minutes, until the top springs back lightly when touched. Let the brownies cool, then cut into 16 squares.
Notes
For an extra indulgent treat, spread chocolate frostingover the cooled brownies.
Allow the brownies to cool completely before slicing for the cleanest cuts and best chewy texture.
