Key Ingredients
- Brown butter: Creates a rich, nutty foundation that enhances all other flavors
- Peanut butter: Frozen dollops create the molten center
- Peanut Butter M&Ms: Provide color, crunch and extra peanut flavor
- Eggs: Must be room temperature for proper mixing
- Premium chocolate chips: Choose high-quality for best results

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.

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.
