Ingredients

  • 1 c. peanut butter
  • 2/3 c. butter
  • 1 1/2 c. brown sugar
  • 1 1/2 c. white sugar
  • 4 eggs
  • 1 Tbsp. vanilla
  • 2 c. flour
  • 2 tsp. baking powder
  • 1 1/2 tsp. salt

Instructions

  1. Mix peanut butter, butter, brown sugar, white sugar, eggs, and vanilla until well combined.
  2. In a separate bowl, whisk together flour, baking powder, and salt.
  3. Gradually add dry ingredients to the wet mixture and mix until just combined.
  4. Spread the mixture in a greased pan and sprinkle with chocolate chips.
  5. Bake at 350° for 30 minutes.
  6. Cut into bars once cooled.

Tips & Substitutions

For a richer flavor, try using natural peanut butter instead of processed. You can also substitute half of the white sugar with coconut sugar for a healthier option. If you're looking for a gluten-free version, use a 1:1 gluten-free flour blend. Make sure to mix the batter gently to avoid overworking it, which can lead to dense bars.

Serving Suggestions

These bars are delightful on their own but pair beautifully with a scoop of vanilla ice cream for a decadent dessert. You can also serve them alongside a glass of cold milk or a cup of coffee. For a fun twist, try drizzling melted chocolate or caramel sauce over the top before serving.

Storage & Reheating

Store leftover Peanut Butter Swirl Bars in an airtight container at room temperature for up to 5 days. For longer storage, you can freeze them by wrapping individual bars in plastic wrap and placing them in a freezer-safe bag. To reheat, simply microwave for 10-15 seconds or thaw overnight in the refrigerator.

Frequently Asked Questions

Can I use creamy peanut butter instead of chunky?

Yes, you can definitely use creamy peanut butter if you prefer a smoother texture in your bars. The choice between creamy and chunky will mainly affect the texture rather than the overall flavor.

What can I use instead of eggs in this recipe?

For a vegan option, you can replace each egg with 1/4 cup of unsweetened applesauce or a flaxseed meal mixture (1 tablespoon ground flaxseed mixed with 3 tablespoons water, let sit for 5 minutes). These alternatives will help bind the ingredients effectively.

How can I make these bars more chocolatey?

To enhance the chocolate flavor, consider mixing in some cocoa powder into the batter or adding chocolate chunks instead of just chocolate chips. This will create a deliciously rich and chocolatey experience!
