Chewy REESES PIECES Peanut Butter Brownies
Brownies That’ll Make You Question Life: Chewy REESE’S PIECES Peanut Butter Brownies
Have you ever had a day where you just need *all* the chocolate? Like, existential crisis level? Yeah, me too! That’s when I whip out this little gem — my Chewy REESE’S PIECES Peanut Butter Brownies. They’re like a hug in dessert form, and honestly, who doesn’t need that?

Okay, so…
Okay, Let’s Talk Ingredients
Let’s hit the grocery store! Grab your list—oh, wait, I’ve got it right here:
– ⅔ cup butter (melted, duh)
– 1⅓ cups granulated sugar (yes, the white stuff)
– 1 cup light brown sugar (for that caramel vibe)
– 4 large eggs (get ready for some richness)
– 2 teaspoons vanilla extract (because vanilla = magic)
– 1 cup creamy or chunky peanut butter (you DO you)
– 2 cups all-purpose flour (don’t skip this part)
– 2 teaspoons baking powder (rise, baby, rise)
– ¼ teaspoon salt (just a pinch to balance it)
– ½ cup Reese’s Pieces (the star of the show!)
You got all that? Great! But don’t get overwhelmed; it’s really just a party of flavors waiting to happen!
So Here’s Why I Make This Constantly
Okay, real talk — these brownies have been my secret weapon for ages! 🤫 Every time I make them, I remember the last time I baked a batch for my best friend’s birthday. I was stressed, like, what do I even bake?! Then BAM! Peanut butter brownies popped into my head.
So, I made them, and as soon as the first tray came out of the oven, my kitchen smelled like heaven. There were literally *people* hanging around just to snag a piece. My friend took a bite, paused, and said, “I’m never leaving.” And honestly, same.

The One Trick That Changes Everything
Here’s the thing — DO NOT OVER MIX! Seriously, I can’t stress this enough. When you mix the flour into the peanut butter goodness, just fold it in until it’s combined. If you overdo it, you’ll end up with these fluffy cake-like brownies. Noooo! We want chewy, fudgy perfection!
Don’t Mess This Up (My Top Tips)
1. Parchment paper is your BFF. Line that pan so you can lift the whole batch out after and not have brownie bits stuck everywhere.
2. Check ’em early! Bake for 30-35 minutes, but start peeking at 28. You want that perfect gooey center.
3. Let them cool for at least 30 minutes — I know, it’s torture. But trust me, they’ll cut better and taste even more amazing!
How to Keep Them From Disappearing (Or, How to Store Them)
Okay, here’s the scoop: if you want them to last more than a day (good luck), just pop them in an airtight container. They’ll stay fresh for about 4-5 days… but I mean, who are we kidding? They’re probably gonna be gone in a flash.
