Essential Techniques

Preparing the Filling
Freeze peanut butter portions for at least 30 minutes until firm. This crucial step ensures clean assembly and perfect melted centers.
Browning the Butter
Heat butter over medium-low until golden brown with nutty aroma. Watch carefully and scrape all browned bits into mixing bowl.
Cooling Process
Allow browned butter to cool until just warm before mixing with other ingredients to prevent cooking the egg.
Mixing Method
Use gentle folding motions when incorporating dry ingredients to maintain tender texture. Dough should be soft but manageable.
Assembly Steps
Flatten each portion, wrap around frozen peanut butter, seal completely, then press to desired thickness.
Baking Guidelines
Remove cookies when edges are golden but centers look slightly underbaked. They'll continue setting as they cool.

These cookies consistently earn rave reviews from both casual snackers and dedicated dessert enthusiasts. The combination of textures and flavors creates an elevated version of classic peanut butter cookies.

Serving Suggestions

Enjoy warm with cold milk for classic comfort. Transform into decadent ice cream sandwiches using premium vanilla ice cream. Serve alongside salty snacks for entertaining or pair with hot beverages for afternoon treats.

Recipe Variations

Experiment with different nut butters or try caramel centers. Add chopped peanuts for extra crunch or finish with flaky sea salt. The basic technique works well with various flavor combinations while maintaining the signature molten center.

Frequently Asked Questions

→ Why can’t I keep the cookie dough for later?
The dough gets harder due to the brown butter solidifying, which can stop the cookies from spreading properly. It’s best to bake it right after making it.
→ How will I know the butter is browned perfectly?
You’ll see golden-brown bits at the bottom and smell a nutty fragrance. Keep stirring so it doesn’t burn, and take it off the heat when those bits first appear.
→ Can I swap smooth peanut butter for crunchy?
Totally! Crunchy works great too and adds more texture. Just make sure it’s at room temperature so scooping is easier.
→ Why do the cookies look a little undercooked?
They’re supposed to look soft in the center when you take them out of the oven. They’ll firm up as they cool on the tray.
→ Can I use other types of M&Ms instead?
Of course! Regular M&Ms or even different flavors will work. Peanut butter M&Ms just pair nicely with the peanut butter center.

Ingredients

→ Cookie Dough

01 ½ cup and 2 tablespoons of packed brown sugar
02 ½ cup unsalted butter, browned
03 2 tablespoons of regular white sugar
04 1 teaspoon of pure vanilla extract
05 1 large egg, at room temperature
06 1⅓ cups all-purpose flour, leveled and spooned
07 ½ teaspoon of baking soda
08 ¼ teaspoon of salt
09 ½ cup of milk chocolate chips, plus extra for garnish
10 ½ cup of peanut butter M&Ms, plus more for topping

→ Filling & Toppings

11 Pretzels for decorations (optional)
12 A few more chocolate chips to sprinkle on top
13 Some extra peanut butter M&Ms for decoration
14 8 tablespoons creamy peanut butter (1 tablespoon per cookie)

Instructions

Step 01

Take a parchment-lined plate and scoop out 8 tablespoons of peanut butter onto it. Freeze them until you’re ready to bake.

Step 02

Chop butter into pieces and melt it in a sturdy pan over medium heat. Keep stirring while it melts, and don’t stop stirring when it starts bubbling. Once it’s golden and smells nutty, take it off the heat and pour it into a heatproof bowl to cool.

Step 03

When your butter has cooled, set your oven to 350°F (or 175°C). Get a baking tray and line it with parchment paper.

Step 04

Take your cooled browned butter and whisk it with brown sugar and granulated sugar in a big mixing bowl. Add in the egg and vanilla, whisking until the whole thing is smooth.

Step 05

Carefully sift the flour, baking soda, and salt into your wet mixture. Fold it in gently, just enough to combine everything. Don’t overdo it.

Step 06

Stir in the peanut butter M&Ms and chocolate chips so they’re spread evenly in the dough.

Step 07

Scoop out ¼ cup-sized chunks of dough or use an ice cream scoop. Flatten each piece, place a peanut butter ball inside, and carefully fold the dough so it completely covers the peanut butter. Gently press the ball down so it’s about 75% flattened.

Step 08

Push a few extra chocolate chips and M&Ms into the tops of the cookies for decoration.

Step 09

Bake half the batch (6 cookies) at a time for about 10 minutes. Stop when the edges start setting and the bottoms turn a light golden color. The centers might not look fully baked yet.

Step 10

When you take the cookies out of the oven, and they’re still hot, you can use a large round cookie cutter or a measuring cup to reshape them if needed. While still warm, you can top each cookie with M&Ms, chocolate chips, or pretzels.

Step 11

Leave the cookies on the baking tray until they cool completely. Enjoy them once they’re cool! If there are leftovers (unlikely), keep them in an airtight container.

Notes

  1. You must bake this dough right after it’s mixed. It won’t keep for later.
  2. These cookies will look a little soft when you take them out of the oven, but they’ll continue setting on the hot tray.
  3. Brown butter adds a nutty, deep flavor that works perfectly with peanut butter and chocolate.
