I found this peanut butter M&M cookie trick while just playing around in my kitchen last year. I wanted something yummy but smaller batch. When you mix the nutty browned butter with that soft peanut butter middle and crunchy candy shells, you get something that's totally next-level. They've become what I make when I want people to think I worked harder than I actually did.

My next-door neighbor walked in while these were sitting out and the aroma alone got her to hang around for a cup of joe. She took one bite, shut her eyes and went, "I need a moment with this cookie" before asking how to make them. It's funny how the easiest treats often get the best reactions.

Basic Components

  • Brown butter: Spending that extra minute browning makes regular butter taste like toffee and takes these cookies up a notch
  • Peanut butter: The frozen chunk in the middle turns all melty and gives that wow factor
  • Peanut Butter M&Ms: These bring fun colors, some crunch, and extra nutty flavor all at once
  • Room temperature eggs: Super important for mixing everything smoothly
  • Quality chocolate chips: Grab the good stuff here since you'll really taste the difference

Cookie Assembly

Peanut Butter Setup
Don't rush freezing those peanut butter drops. This trick keeps everything neat when you wrap dough around them. My first try with room temp peanut butter was a total disaster - it went everywhere! Now I freeze them at least 30 minutes and everything works smoother, plus you get that perfect runny center after baking.
Butter Magic
Keep an eye on your butter as it changes from yellow to gold to brown. It'll bubble up before tiny brown flecks appear at the bottom. You'll smell when it's done - goes from just buttery to almost like hazelnuts. I've ruined more batches than I can count by walking away. These days I keep the heat lower and stay put. Those brown bits are flavor gold - scrape them all in!
Cooling Down
Let that brown butter cool till it's just warm, not hot. If it's too hot when the egg goes in, you'll cook parts of it. I made that mistake once and got egg bits throughout my cookies. Now I use cooling time to get everything else ready, which makes the whole process faster.
Working With Dough
Stir this dough just until mixed. Too much mixing makes tough cookies instead of soft ones. I use a spatula instead of a mixer for the dry ingredients, which works better. The dough's a bit thicker than usual because of the brown butter, but still soft enough to scoop. If it seems too crumbly, your butter might have cooked down too much - a splash of milk fixes it.
Putting It Together
Push each ball of dough flat, drop the frozen peanut butter in the middle, then carefully fold dough around it making sure there aren't any gaps where filling could escape. Press the ball down most of the way so they spread right. I've found slightly damp hands keep the dough from sticking while you work.
Baking Right
Don't take your eyes off these cookies while they bake - they can go from perfect to overdone really fast. They should look golden on bottom but slightly soft on top when you take them out. They'll finish cooking as they cool. I start checking at 8 minutes, though 10 usually works in my oven. Don't leave them in longer or you'll lose the gooey middle.

When my kid had friends over after school recently, they wolfed these down in seconds. One actually asked if I'd show his mom how to make them - pretty much the best compliment a hungry teenager can give. It's funny how the easiest treats often turn into everyone's favorites.

Tasty Companions

These cookies taste amazing while still warm with cold milk on the side. For a fancier treat, put some vanilla ice cream between two cookies for a next-level ice cream sandwich. On game days, I put them out with salty pretzels for that sweet-salty combo everyone loves. My kids go crazy for them with hot cocoa when it's cold outside.

Flavor Twists

Switch up the filling with almond butter or cookie butter for something different. You can swap peanut butter M&Ms for caramel ones and use caramel inside instead of peanut butter for another surprise. A tiny sprinkle of fancy salt on top before baking makes all the flavors pop. Last month I threw in some chopped peanuts for extra crunch, which my friends who like more texture really enjoyed.

I've whipped up these peanut butter M&M cookies for everything from kids' snacks to dinner party desserts, and they always get raves. There's something truly special about how the nutty brown butter works with that sweet-salty peanut butter inside. My little girl now asks to make them for school sales because they "make everyone go crazy" - high praise from the playground crowd! Sometimes the cookies people remember aren't the fanciest ones - they're just the ones with a little surprise in each bite.

Frequently Asked Questions

→ Why shouldn't I chill the cookie dough?
Brown butter hardens as it cools. If you hold off baking, the dough sets too much, and your cookies won't spread properly.
→ How can I tell when the butter's ready?
It'll smell nutty and turn golden with small brown bits at the pan's bottom. Stir consistently so it doesn't burn, and take it off heat quickly.
→ Can I swap smooth peanut butter for crunchy?
Totally! Crunchy peanut butter adds nice texture. Let it sit at room temperature, so it's easier to scoop and spread.
→ Why do my cookies still look raw?
Pull them out when they're slightly undercooked. They'll continue setting up on the hot tray while cooling down.
→ Is it okay to use regular M&Ms instead?
Of course! Peanut butter M&Ms play well with the filling, but plain or even other types will still taste great.

Difficulty: Intermediate

Cuisine: American

Yield: 8 Servings (8 cookies)

Dietary: Vegetarian

Ingredients

→ Dough Base

01 ½ cup of butter (unsalted), browned
02 ½ cup + 2 tbsp dark brown sugar, packed
03 2 tbsp sugar, regular
04 1 large egg, at room temp
05 1 tsp vanilla essence
06 1⅓ cups of plain flour, leveled and lightly spooned in
07 ¼ tsp table salt
08 ½ tsp baking soda powder
09 ½ cup of milk chocolate chips, and some extras to sprinkle
10 ½ cup peanut butter M&Ms, plus a handful for topping

→ Filling & Extras

11 8 tbsp creamy peanut butter (1 tbsp per cookie)
12 A few extra M&Ms for on top
13 Additional chocolate chips for garnishing
14 Optional: Pretzels for decorating

Instructions

Step 01

Drop 8 evenly-sized scoops of peanut butter onto a parchment-lined tray or plate, then pop it in the freezer until you need them.

Step 02

Chop up your butter and toss it into a heavy pot on medium heat. Stir it as it melts down, and keep going until it turns golden brown and smells nutty (foaming is totally normal). Pour it into a bowl and let it cool.

Step 03

Preheat your oven to 350°F (175°C) once your browned butter has cooled. Lay a sheet of parchment on a baking tray to stop sticking.

Step 04

In a big bowl, whisk together your cooled browned butter, both sugars, and mix well. Add the egg and vanilla next, stirring until silky smooth.

Step 05

Sift flour, soda, and salt over the wet mix. Gently fold it all together but don’t overdo it—you just want the flour streaks to disappear.

Step 06

Throw in your chocolate chips and M&Ms. Stir until you’ve got them spread evenly throughout the dough.

Step 07

Grab about ¼ cup of dough (or use an ice cream scoop). Flatten it out, place a frozen peanut butter scoop in the center, and wrap the dough around to seal it. Give each ball a slight press for even baking.

Step 08

Dot the tops of each cookie with a few extra M&Ms and chocolate chips for that bakery-style finish.

Step 09

Bake 6 cookies per tray for about 10 minutes, just until the edges firm up and the bottoms turn golden. Don’t worry if the centers still look soft.

Step 10

While still warm, tidy up their shape using a round cookie cutter if you want perfect circles. Push on more M&Ms, chocolate chips, or pretzels while they're warm.

Step 11

Let cookies sit on the tray to cool completely. Once firm, eat right away or keep them in an airtight container.

Notes

  1. This dough can’t be stored for later. Bake it right after mixing.
  2. Cookies might look a little underbaked when they come out but will finish cooking on the hot tray.
  3. Cooking butter until it's browned brings out its deep, nutty flavor, perfect for this recipe.
