½ cup (1 stick) unsalted butter, melted

¾ cup creamy peanut butter
¾ cup brown sugar, packed
¼ cup granulated sugar

1 large egg
1 tsp vanilla extract

Add-ins & Toppings (Optional but Recommended):

½ cup chopped peanuts (or walnuts/pecans)

¼ cup crushed pretzels for salty crunch
Mini peanut butter cups or drizzle of melted chocolate

✅ For a gluten-free version, use a 1:1 gluten-free flour blend.

How to Make Peanut Butter Passion Bars

Step 1: Preheat & Prep

Preheat oven to 350°F (175°C).
Line an 8×8 or 9×9-inch baking pan with parchment paper or lightly grease.

Step 2: Mix the Wet Ingredients

In a large mixing bowl, whisk together melted butter, peanut butter, brown sugar, and granulated sugar until smooth.

Add the egg and vanilla, mixing until fully combined.

Step 3: Add the Dry Ingredients

In a separate bowl, whisk together flour, baking soda, and salt.
Slowly add the dry ingredients to the wet mixture and stir until just combined.

Fold in chocolate chips, nuts, or other mix-ins.

Step 4: Spread and Bake

Spread the dough evenly into the prepared pan.
Top with additional chocolate chips or chopped nuts if desired.

Bake for 22–26 minutes, or until the top is golden and a toothpick comes out mostly clean with a few moist crumbs.

⏳ Do not overbake — the bars continue to set as they cool.

Step 5: Cool and Slice

Let the bars cool in the pan for 20–30 minutes.
Lift out using parchment paper and transfer to a wire rack.

Slice into 12–16 bars and enjoy!

Tips for the Best Peanut Butter Passion Bars

✅ Use creamy peanut butter for a smooth, moist texture. Natural peanut butter works if it’s well stirred.
✅ Melted butter makes the batter easy to stir and results in fudgier bars.
✅ Don’t overmix the batter — stir just until combined.
✅ Bake just until the center is slightly underdone for gooey texture.
✅ Let them cool completely before slicing for clean edges.

Peanut Butter Passion Bar Variations

You can totally make these your own! Try some of these fun flavor ideas:

🍫 Chocolate Swirl Bars:

Add ¼ cup melted chocolate and swirl it into the top before baking.

🍓 PB&J Bars:

Swirl in ¼ cup raspberry or strawberry jam on top before baking.

🥥 Peanut Butter Coconut Bars:

Fold in ½ cup shredded coconut and top with a sprinkle of sea salt.

🥜 Chunky Monkey Style:

Add chopped bananas, walnuts, and chocolate chunks.

🥛 A cold glass of milk or dairy-free almond/oat milk
🍨 A scoop of vanilla or chocolate ice cream
☕ A hot cup of coffee or chai latte

🍓 Fresh strawberries or sliced bananas for contrast

Frequently Asked Questions (FAQs)

An 8×8-inch pan makes thicker, chewier bars; a 9×9-inch pan yields slightly thinner bars with crispier edges.

Can I double the recipe?

Yes — double all ingredients and bake in a 9×13-inch pan for 30–35 minutes.
