AllRecipes.com has a Chewy Peanut Butter Brownie Recipe with over 600 reviews that average over four stars out of five. Including prep and baking times, the brownies are ready in about 40 minutes.
To complete this recipe, the baker needs 1/2 cup of peanut butter and 1/3 cup of softened margarine for the first mixing step. The second step requires 2/3 cup of white sugar, 1/2 cup packed brown sugar, two eggs and 1/2 teaspoon vanilla extract. The final step calls for 1 cup of flour, 1 teaspoon baking powder and 1/4 teaspoon salt.
The first step is to preheat the oven to 350 Fahrenheit. A 9-by-9-inch baking pan also needs to be greased. In a mixing bowl, the peanut butter and margarine are stirred or beaten with an electric mixer until creamy. The sugar, vanilla and eggs are then added to the peanut butter mixture. These ingredients are blended until fluffy. The next step is to add the flour, salt and baking powder, and stir until well mixed.
The brownie batter is poured into the greased baking dish and placed into the preheated oven for 25 to 35 minutes. The brownies are cooked when the top springs back after being touched. Once the brownies are done, they can be removed from the oven and allowed to cool before frosting or eating.
