Brookies are those genius desserts that combine the best of both worlds – chewy chocolate chip cookies on the bottom and fudgy brownies on top. If you’ve never had one, you’re missing out. And if you have had one, you know exactly what I’m talking about. They’re soft, they’re rich, and they’re the kind of thing you eat standing at the counter at 10 PM telling yourself “just one more.”

But here’s where it gets even better. Take those brookies and stuff a Reese’s peanut butter cup right in the middle. Now you’ve got something that’s basically a fancy molten lava cake, except easier to make and arguably better. The peanut butter gets all melty in the center while everything bakes, and when you bite into one it’s like hitting the jackpot.

I make these whenever I need to bring dessert somewhere and want people to think I spent hours in the kitchen. The secret? It’s literally three ingredients and a muffin tin. That’s it. No fancy technique, no complicated steps. Just layer, stuff, bake, and try not to eat them all before anyone else gets there.

Why You’ll Love These Brookies

Three ingredients – Cookie dough, brownie mix, peanut butter cups. That’s the whole shopping list. You can’t get much simpler than that.

Tastes fancy but isn’t – These look and taste like you worked really hard, but you basically just assembled stuff and baked it.

Cookie and brownie together – Why choose between cookies and brownies when you can have both in one bite?

Peanut butter surprise – That melty peanut butter center is what takes these from good to “can I have the recipe?”

No mixer needed – Everything comes premade. You’re just putting things together, not actually baking from scratch.

Perfect portions – The muffin tin makes individual servings, so you don’t have to cut squares and make a mess.

Always a hit – I’ve never met anyone who didn’t like these. Kids go crazy for them, adults pretend to have self-control and then eat three.

Ingredients

• 1 package refrigerated chocolate chip cookie dough (the tube kind from the refrigerated section)
• 1 box brownie mix, prepared according to package directions (you’ll need whatever eggs, oil, and water the box calls for)
• 12 full-size Reese’s peanut butter cups, unwrapped

Directions

Get everything ready Crank your oven to 350°F and grab a 12-cup muffin tin. Spray every single cup really well with baking spray – don’t skip any or you’ll regret it later when you’re trying to get these out. While the oven’s heating up, mix up your brownie batter according to whatever the box says. Set it aside.

Make the cookie base Open up that tube of cookie dough and divide it into 12 equal pieces. Eyeball it or weigh them if you’re feeling precise, but honestly, close enough is fine. Take each piece and press it into the bottom of a muffin cup. You want to flatten it out so it covers the whole bottom – don’t just plop a ball in there. This is your cookie layer.

Add the peanut butter cups Unwrap all your peanut butter cups (this is the most annoying part, honestly). Take one and press it upside down right into the center of each cookie dough cup. Press it down a little so it sits in there and doesn’t just float around.

Top with brownie batter Now spoon that brownie batter over the top of each one. Fill them up about 3/4 of the way – they need room to rise. Make sure the peanut butter cup is completely covered with batter. It’s okay if it’s not perfect, they’ll even out as they bake.

Bake them Stick the whole muffin tin in the oven and bake for 20-25 minutes. You’re looking for the brownie tops to be set and not jiggly, and maybe a toothpick inserted into the brownie part (not the peanut butter cup) comes out with just a few moist crumbs.

Cool and remove Here’s the hard part – let them cool in the pan for at least 15-20 minutes. I know they smell amazing and you want to eat them right now, but if you try to take them out too soon they’ll just fall apart. Once they’re cool, run a butter knife around the edges of each one and gently lift them out. Serve them up and watch people’s faces when they bite into that peanut butter center.

Variations to Try

Different candy – Try Snickers, Milky Way, Rolos, or even Oreos stuffed in the middle instead of peanut butter cups.

White chocolate version – Use white chocolate chip cookie dough and blonde brownie mix for a different take.

Mint chocolate – Use mint brownie mix and top with an Andes mint instead of a peanut butter cup.

Caramel center – Stuff a Rolo or caramel square in there for a gooey caramel surprise.

Double chocolate – Use double chocolate cookie dough for even more chocolate flavor.

Topped with sea salt – Sprinkle a little flaky sea salt on top before baking for that sweet-salty thing.

Serving Suggestions

These are great on their own, but here are some ways to make them even better:

• With ice cream – Warm brookie with a scoop of vanilla ice cream melting on top is basically heaven
• Whipped cream – A dollop of whipped cream makes them feel fancy
• Chocolate sauce – Drizzle some chocolate or caramel sauce over the top
• Peanut butter drizzle – Melt some peanut butter and drizzle it over for extra peanut butter flavor
• Fresh berries – Throw some raspberries on the side to pretend you’re being healthy

Storage Tips

Room temperature – Keep them in an airtight container for 2-3 days. They’ll stay soft and chewy.

In the fridge – They’ll last about a week in the fridge if you cover them well. Let them come to room temp before eating or warm them up.

Reheating – Pop one in the microwave for 10-15 seconds to get that warm, melty center back.
