Imagine a brownie that’s halfway between a candy bar and a hug. The chocolate is so intense, it’s basically a cocoa bomb, while the peanut butter swirl adds this creamy, salty contrast that’s borderline illegal. Texture?

Chewy edges, fudgy centers—like a bakery-quality treat without the $8 price tag. And let’s be real: peanut butter and chocolate is the Beyoncé and Jay-Z of flavor combos. Unbeatable.

Ingredients

Grab your grocery list and prepare for glory.

The secret weapon? Brown butter. It’s like regular butter’s cooler, nuttier cousin.

Pro tip: If you’re out of peanut butter chips, chop up Reese’s cups instead (no judgment here).

• 1 cup unsalted butter, browned
• 1 ¼ cups dark chocolate chips (60% cacao or higher)
• ¾ cup creamy peanut butter (not natural—too oily)
• 3 large eggs, room temp
• 1 tbsp vanilla extract (yes, a full tablespoon)
• 1 cup granulated sugar
• ½ cup brown sugar
• ¾ cup all-purpose flour
• ½ cup cocoa powder (Dutch-processed for extra depth)
• ½ tsp sea salt (plus extra for sprinkling)

Step-by-Step Instructions

1. Brown the butter. Melt it in a saucepan over medium heat, swirling until it smells like toffee. Pour into a bowl to cool slightly. This step is non-negotiable—it’s what gives these best decadent chocolate peanut butter brownies their nutty magic.
2. Melt the chocolate. Stir chocolate chips into the warm butter until smooth.
   

   If it seizes, add a teaspoon of coconut oil to rescue it.

   
   
3. Whisk the eggs and sugars. Beat them for a full 2 minutes until pale and fluffy. This creates the crackly top we all crave.
4. Fold in dry ingredients. Use a spatula, not a whisk, to keep the batter dense. Overmixing = cakey brownies (aka sadness).
5. Swirl the peanut butter. Drop spoonfuls onto the batter, then drag a knife through for Instagram-worthy streaks.
6. Bake at 350°F for 25 minutes. The center should jiggle slightly—they’ll firm up as they cool.
   

   Cutting too soon = molten chaos.

   
   

Storage Instructions

These disappear fast, but if you’ve got leftovers (lol), store them in an airtight container. Room temp: 3 days max. Fridge: 1 week (microwave for 10 seconds to revive the fudginess). Freezer: Wrap individually in foil, then freeze for up to 3 months. Pro move: freeze half the batch before your family finds them.

Common Mistakes to Avoid

• Using cold eggs. They won’t blend smoothly, and your batter will look like a science experiment gone wrong.

• Skimping on salt. That pinch on top balances the sweetness. Don’t you dare forget it.

The world is your brownie.

FAQs

Can I freeze this?

Absolutely. Slice, wrap in parchment, and freeze in a zip-top bag. Thaw at room temp or microwave straight from frozen (15 seconds = gooey perfection).

What’s the best substitute for peanut butter?

Almond butter or sunflower seed butter work, but the flavor shifts.

Cashew butter is the closest match for creaminess.

How long does it stay fresh?

3 days at room temp, but good luck keeping them that long. For maximum freshness, store with a slice of bread—it keeps them soft.

Is this kid-friendly?

Uh, have you met children? They’ll inhale these.

Just maybe cut the espresso powder if you’re not into tiny humans bouncing off walls.

Can I prep it ahead of time?

Yes! Make the batter, pour into the pan, cover, and refrigerate for up to 24 hours before baking. Add 2-3 extra minutes to the bake time.
