Prep & Cook Time
- Prep Time: 10 minutes
- Cook Time: 22 minutes
- Total Time: 32 minutes
- Servings: 24 bars
Ingredients
- 1 3/4 cups all purpose flour
- 3/4 teaspoons baking soda
- 1/4 teaspoons salt
- 3/4 cup unsalted butter (1 1/2 sticks (softened))
- 1 cup creamy peanut butter
- 1/2 cup sugar
- 1/2 cup packed light brown sugar
- 1 large egg
- 1 teaspoon vanilla
- 12 oz chopped semi sweet chocolate (or a bag of chocolate chunks or chips)
Instructions
- Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on two sides for easy removal.
- In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Set aside.
- In a large mixing bowl, use an electric mixer to cream together the softened unsalted butter, creamy peanut butter, sugar, and packed light brown sugar until smooth and fluffy, about 2-3 minutes.
- Beat in the large egg and vanilla extract until fully incorporated.
- Use a spatula to fold in the chopped semi-sweet chocolate (or chocolate chunks/chips) until evenly distributed.
- Transfer the dough to the prepared baking pan. Press it into an even layer, pushing it into the corners.
- Bake for 20-22 minutes, or until the edges are lightly golden and the center appears set. The bars will continue to firm up as they cool.
- Let the pan cool completely on a wire rack. Once cool, use the parchment overhang to lift the slab out of the pan. Cut into 24 squares.
Variations
- Fudgy Swirl: Before baking, warm 1/4 cup of extra peanut butter and drizzle it over the dough, then swirl gently with a knife for a marbled effect.
- Salted Caramel Finish: Immediately after baking, sprinkle the top lightly with flaky sea salt for a sweet and salty contrast.
- Blondie-Style: Bake in a 9×9 inch pan for a thicker, denser bar, adjusting the bake time to 25-28 minutes.
- Ice Cream Sandwiches: Let bars cool completely, then sandwich a scoop of vanilla ice cream between two bars and freeze.
Tips for Success
- Ensure your butter is properly softened to room temperature for easy creaming and a uniform texture.
- For extra chewy bars, avoid overbaking; remove them from the oven when the center still looks slightly soft.
- Use a sharp knife to cut clean bars, wiping it clean between cuts for neat edges.
- If using natural peanut butter, stir it very well first to incorporate any separated oil.
Storage & Reheating
Store cooled bars in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months. To enjoy warm, place a bar on a microwave-safe plate and heat for 10-15 seconds until the chocolate is slightly melted.
FAQ
Can I use chunky peanut butter?
Yes, chunky peanut butter works perfectly and will add a bit of peanut texture to the bars.
Can I make these gluten-free?
You can substitute the all-purpose flour with a 1:1 gluten-free baking blend, though the texture may be slightly more crumbly.
Why are my bars dry or crumbly?
This is usually due to overmeasuring the flour. For best results, spoon the flour into the measuring cup and level it off with a knife.
Can I use dark or milk chocolate instead?
Absolutely. You can substitute the semi-sweet chocolate with an equal amount of dark chocolate chips, milk chocolate chunks, or even white chocolate.
Do I have to use a mixer?
While a mixer makes creaming easier, you can mix the dough by hand with a sturdy spatula and some elbow grease.
How do I know when the bars are done baking?
The edges should be lightly browned and pulling away from the pan slightly, and the center should no longer look wet or jiggle. A toothpick inserted will have a few moist crumbs.
