Reese’s Pieces Brownies from Scratch are my go to fix for that moment when you want something homemade, but you also want it to feel a little fun and candy shop special. I started making these on weekends when friends would casually drop by and I needed a quick dessert that made everyone light up. You get that deep chocolate brownie base, plus little pops of peanut butter candy crunch in every bite. It’s the kind of pan you set on the counter and somehow half of it disappears before it even cools. If you have a bag of Reese’s Pieces hanging around from movie night, this is the best way I know to use them.
Reese’s Pieces Peanut Butter Brownies Recipe
This is the brownie recipe I pull out when boxed mix feels too plain, but I still want something simple. The base is rich, chewy, and very chocolate forward, and then the candy brings that sweet peanut butter vibe without you needing to swirl in a whole jar of peanut butter. I love that you can dress these up for a party or keep them totally casual for a Tuesday night dessert.
If you’re a brownie person in general, you might also like my cozy, classic style favorites like Lunch Lady Brownies when you want that nostalgic school cafeteria chocolate hit. Different vibe, same comfort level.
My favorite way to serve them: slightly warm, with a pinch of flaky salt on top and a cold glass of milk. If you want to be extra, add a scoop of vanilla ice cream and call it a full on treat night.

About our Reese’s Pieces Brownies recipe
I’ve tested this a bunch of times because I’m picky about brownie texture. I don’t want dry cake brownies, and I also don’t want something so gooey it feels underbaked in the middle. This version lands in that happy middle: chewy edges, soft center, and the candy stays a little crunchy on top.
A quick note on trust and results, because I know recipes online can be hit or miss. I measure carefully, I keep the steps simple, and I bake these in a standard 9 by 9 inch pan so you don’t have to guess.
“I made these for my kids soccer snack day and they were gone in ten minutes. I loved how they stayed soft even the next day, and the Reese’s Pieces on top made them look bakery cute without extra work.”
If you ever want brownies with a different twist, I’m also into veggie based ones like avocado coconut sweet potato brownies. They’re surprisingly rich and great when you want something a little different in the same chocolate lane.

Soft and chewy brownies combine with crunchy Reese’s Pieces
This is the whole reason Reese’s Pieces Brownies from Scratch work so well. The brownie itself is soft and chewy, and then the Reese’s Pieces add these tiny crunchy bits that keep each bite interesting. It’s not just sweetness, it’s texture. And if you’re like me, texture is what keeps you going back for another square.
Here’s what I’ve noticed after making them a lot:
When you add the candy matters. If you mix all the Reese’s Pieces into the batter, they can bleed color and get a little soft. I like to fold in a small handful, then sprinkle most of them on top right before baking. That way you get both, some candy inside, and that pretty crunchy top.
Don’t overbake. The center should look set, but if you wait until it looks totally dry, you’ll lose the chewy magic. I start checking early and pull the pan when a toothpick comes out with moist crumbs. Not raw batter, just fudgy crumbs.
And if you’re a big fan of super fudgy brownies with barely any effort, you should peek at these Instant Pot fudgy chocolate brownies. Totally different method, but it’s another great option for chocolate emergencies.
Ingredients for rich and chewy brownies
I’m keeping this real: you don’t need fancy chocolate bars or anything complicated. These are pantry friendly, and the candy does a lot of the flavor work. For the best Reese’s Pieces Brownies from Scratch, make sure your cocoa powder smells fresh and chocolatey. Old cocoa can taste dusty and flat.
- Unsalted butter melted (gives that rich brownie taste)
- Granulated sugar for that classic crackly top
- Brown sugar for chewiness and deeper flavor
- Eggs at room temp if you can (they mix in smoother)
- Vanilla extract
- Unsweetened cocoa powder
- All purpose flour
- Salt just a little to balance sweetness
- Reese’s Pieces plus a few extra for the top
- Optional: chocolate chips if you want them extra rich
Small tip that helps a lot: if you want super clean slices, chill the brownies first. If you want the gooey, warm bite, slice them after they cool for about 30 minutes and accept that the first piece might be a little messy. That is part of the charm.
How to make the simple brownie recipe
This is the part where I tell you it’s hard, but it’s honestly not. Reese’s Pieces Brownies from Scratch are basically melt, mix, stir, bake. I use one bowl most of the time, and nobody has ever complained about that.
Step by step directions
1) Heat the oven and prep the pan. Set your oven to 350 F. Line a 9 by 9 inch pan with parchment paper or lightly grease it. The parchment makes lifting and slicing so much easier.
2) Melt butter and mix sugars. Melt the butter and let it cool for a minute so it’s warm, not piping hot. Stir in granulated sugar and brown sugar until it looks glossy.
3) Add eggs and vanilla. Mix in the eggs one at a time, then add vanilla. Stir until the batter looks smooth and a little thicker.
4) Add dry ingredients. Sprinkle in cocoa powder, flour, and salt. Stir just until you don’t see flour streaks. Overmixing can make brownies tough, so stop when it comes together.
5) Add Reese’s Pieces. Fold in a small handful, then spread batter into the pan. Sprinkle the rest of the Reese’s Pieces on top and gently press them in so they stick.
6) Bake. Bake about 22 to 30 minutes, depending on your oven and how fudgy you like them. Start checking at 22 minutes. Look for set edges and a center that doesn’t jiggle like liquid.
7) Cool before slicing. Let them cool in the pan. If you slice too early, they’ll fall apart a bit. If you can wait, you’ll get those neat squares.
If you need a gluten free option for a friend, I’ve also made versions inspired by these deliciously fudgy gluten free brownies. You can swap in a good one to one gluten free flour blend and still get that chewy vibe, just keep an eye on bake time.
Little troubleshooting notes that save a batch
If they turn out dry: they probably baked too long. Next time, pull them earlier and let carryover heat finish the middle.
If the middle seems too gooey: give them time to cool. Brownies keep setting as they cool, and the chocolate firms up.
If the candy sinks: save most Reese’s Pieces for the top and press them in lightly right before baking.
Common Questions
Can I use a 9 by 13 pan instead?
You can, but the brownies will be thinner and bake faster. If you want a full thicker pan, you should double the recipe.
Do Reese’s Pieces melt in the oven?
They soften a bit, but they mostly hold their shape. The top ones can get slightly crackly and that’s honestly my favorite part.
How do I store them?
Keep them in an airtight container at room temp for about 3 days. If your kitchen is warm, store them in the fridge so they stay chewy and fresh.
Can I freeze them?
Yes. Slice, wrap each piece, and freeze for up to 2 months. Thaw on the counter or microwave for a quick warm brownie moment.
What if I only have natural peanut butter, not Reese’s Pieces?
You can swirl peanut butter into the batter, but it will be a different texture. The candy is what gives the little crunchy pops, so it won’t be exactly the same.
