Get ready to experience peanut butter in a whole new light!
Ingredients:
- 1 cup (2 sticks) unsalted butter, softened
- 1 cup granulated sugar
- 1 cup packed brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup creamy peanut butter
- 2 1/2 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1 cup milk chocolate chips
- 1 cup peanut butter chips
Preparing the Dough:
- Cream the butter and sugars: In a large bowl, or the bowl of your stand mixer fitted with the paddle attachment, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. This usually takes about 3-5 minutes. Make sure to scrape down the sides of the bowl occasionally to ensure everything is evenly mixed. You don’t want any lumps of butter hiding at the bottom!
- Incorporate the wet ingredients: Beat in the eggs one at a time, mixing well after each addition. Then, stir in the vanilla extract and peanut butter until everything is well combined and smooth. The peanut butter might make the mixture a little stiff, but that’s perfectly normal.
- Combine the dry ingredients: In a separate medium bowl, whisk together the flour, baking soda, baking powder, and salt. Whisking is important to distribute the baking soda and baking powder evenly throughout the flour, which will help the bars rise properly.
- Gradually add the dry ingredients to the wet ingredients: Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix the dough, as this can result in tough bars. Overmixing develops the gluten in the flour, which can make the bars dense and chewy instead of soft and tender. Stop mixing as soon as the flour disappears.
- Stir in the chocolate and peanut butter chips: Gently fold in the milk chocolate chips and peanut butter chips until they are evenly distributed throughout the dough. I like to use a rubber spatula for this step to avoid overmixing.
Baking the Bars:
- Prepare the baking pan: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan. You can also line the pan with parchment paper, leaving an overhang on the sides, for easy removal of the bars after baking. This is my preferred method because it makes cleanup a breeze!
- Press the dough into the pan: Press the dough evenly into the prepared baking pan. You can use your fingers or the back of a spoon to spread the dough. Make sure the dough is evenly distributed to ensure the bars bake evenly.
- Bake the bars: Bake for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs attached. The baking time may vary depending on your oven, so keep an eye on the bars and check them frequently after 25 minutes.
- Cool the bars: Let the bars cool completely in the pan before cutting into squares. This is important because the bars will continue to set as they cool. If you try to cut them while they are still warm, they will be crumbly and difficult to handle. If you used parchment paper, you can lift the bars out of the pan and place them on a cutting board to make cutting easier.
Optional: Peanut Butter Drizzle
For an extra touch of peanut butter goodness, you can drizzle melted peanut butter over the cooled bars. Here’s how:
- Melt the peanut butter: Place about 1/2 cup of peanut butter in a microwave-safe bowl. Microwave in 30-second intervals, stirring in between, until the peanut butter is melted and smooth. Be careful not to overheat the peanut butter, as it can burn easily.
- Drizzle the peanut butter: Drizzle the melted peanut butter over the cooled bars. You can use a spoon or a piping bag to drizzle the peanut butter.
- Let the peanut butter set: Let the peanut butter set completely before cutting the bars. This will prevent the peanut butter from smearing when you cut the bars.
Cutting and Serving:
- Cut the bars: Once the bars are completely cooled, cut them into squares. The size of the squares is up to you, but I usually cut them into about 2-inch squares.
- Serve and enjoy: Serve the peanut butter sandwich bars and enjoy! These bars are perfect for a snack, dessert, or even a potluck. They are also great for packing in lunchboxes.
Tips and Variations:
- Use different types of chocolate chips: You can use any type of chocolate chips you like in these bars. White chocolate chips, dark chocolate chips, or even a combination of different types of chocolate chips would be delicious.
- Add nuts: Add chopped nuts, such as peanuts, walnuts, or pecans, to the dough for extra flavor and texture.
- Use different types of peanut butter: You can use crunchy peanut butter instead of creamy peanut butter for a more textured bar.
- Make them gluten-free: To make these bars gluten-free, simply substitute the all-purpose flour with a gluten-free all-purpose flour blend. Make sure to use a blend that contains xanthan gum, as this will help to bind the ingredients together.
- Store the bars: Store the peanut butter sandwich bars in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. You can also freeze the bars for up to 2 months.
- Don’t overbake: Overbaking will result in dry, crumbly bars. Be sure to check the bars frequently while they are baking and remove them from the oven as soon as they are done.
- Let them cool completely: Letting the bars cool completely before cutting them is important because they will continue to set as they cool. If you try to cut them while they are still warm, they will be crumbly and difficult to handle.
- For a softer bar: If you prefer a softer bar, you can reduce the baking time by a few minutes.
- For a chewier bar: If you prefer a chewier bar, you can add a tablespoon of molasses to the dough.
- Experiment with toppings: Get creative with the toppings! You can sprinkle the bars with chopped nuts, sprinkles, or even a drizzle of chocolate ganache.
Troubleshooting:
- Bars are too dry: If your bars are too dry, you may have overbaked them. Be sure to check the bars frequently while they are baking and remove them from the oven as soon as they are done. You can also try adding a tablespoon of milk or sour cream to the dough to add moisture.
- Bars are too crumbly: If your bars are too crumbly, you may have overmixed the dough. Be careful not to overmix the dough, as this can result in tough bars. You can also try adding a tablespoon of oil to the dough to add moisture.
- Bars are too dense: If your bars are too dense, you may have used too much flour. Be sure to measure the flour accurately and avoid packing it into the measuring cup. You can also try adding a teaspoon of baking powder to the dough to help the bars rise.
- Bars are too greasy: If your bars are too greasy, you may have used too much butter. Be sure to measure the butter accurately and avoid using softened butter that is too melted.
- Bars are not baking evenly: If your bars are not baking evenly, your oven may not be calibrated correctly. You can use an oven thermometer to check the temperature of your oven and adjust it accordingly. You can also try rotating the pan halfway through baking to ensure even baking.

If you’re feeling adventurous, try using a different type of nut butter, such as almond butter or cashew butter. The possibilities are endless!A Few More Ideas:
* Add a layer of jelly: Before adding the top crust, spread a thin layer of your favorite jelly (grape, strawberry, or raspberry would all be delicious) over the peanut butter filling. * Make them gluten-free: Simply substitute the all-purpose flour in the crust with a gluten-free all-purpose flour blend. * Add some spice: A pinch of cinnamon or nutmeg in the crust adds a warm, comforting flavor. * Make them vegan: Use a vegan butter substitute and a flax egg (1 tablespoon of ground flaxseed mixed with 3 tablespoons of water) in the crust.
