How to Make Peanut Butter Chocolate Chip Bars?
Here’s your step-by-step guide to baking these delicious bars.
Step 1: Prepare the Pan
Preheat your oven to 350°F (176°C). Grease an 8×8-inch baking pan with butter or non-stick spray. Line it with parchment paper, leaving an overhang on two sides for easy lifting later.
Step 2: Mix the Dry Ingredients
Grab a medium bowl and whisk together the flour, baking soda, and cornstarch. Set this mixture aside for later. This step ensures your bars rise evenly and stay tender.
Step 3: Combine the Wet Ingredients
Melt the unsalted butter and allow it to cool slightly. Mix it with light and dark brown sugar in a large bowl. Whisk until the mixture becomes smooth and free of lumps.
Step 4: Add the Remaining Wet Ingredients
Whisk in the eggs and vanilla extract until fully incorporated. Follow this with the creamy peanut butter, which gives the bars their rich and nutty flavor.
Step 5: Combine Wet and Dry Mixtures
Slowly fold the dry ingredients into the wet mixture using a spatula. Be gentle to avoid over-mixing, which can make the bars dense. 🥄✨
Step 6: Add the Chocolate Chips
Pour in the semi-sweet chocolate chips and mix until they’re evenly distributed. You can add extras on top for a pretty finish if you like! 🍫💖
Step 7: Transfer and Bake
Spread the dough evenly into the prepared pan. Pop it into the oven for 28-35 minutes. You’ll know it’s ready when a toothpick inserted in the center comes out with a few moist crumbs. 🎂🔥
Step 8: Cool and Slice
Allow the bars to cool in the pan for 10–15 minutes. Lift them out carefully using the parchment paper and slice into squares. Serve and enjoy! 😋🎉
Tips for Making the Recipe
Get the best results with these helpful tips!
- Room Temperature Ingredients: Bring your eggs to room temperature before mixing to help create a smooth batter.
- Use the Right Peanut Butter: Stick with creamy peanut butter for the perfect texture. Natural peanut butter can make the batter too runny.
- Cooling Is Key: Wait until the bars are fully cool before slicing to prevent them from crumbling.
How to Serve Peanut Butter Chocolate Chip Bars?
These bars are perfect as-is but can be elevated with simple additions. Serve them with a cold glass of milk or a scoop of vanilla ice cream for a super indulgent treat. For a party, arrange them on a pretty platter and dust them lightly with powdered sugar or drizzle melted chocolate on top for a decorative touch.
