Chop the butter into smaller pieces. Drop it in a sturdy pot over medium heat. Keep stirring as it melts and then turns into a lovely golden shade. A foamy layer will form—completely normal. Once it looks golden brown, take it off the stove and pour it into a bowl that's heatproof to cool.
02 -
While the butter cools down, crank the oven to 350°F (175°C). Grab your flour, baking soda, and salt. Sift them together into one bowl.

Once the browned butter is at room temperature, mix it in a big bowl with both the brown and white sugars, the egg, and your vanilla. Whip it all up until you can’t see any streaks.

Toss the sifted dry ingredients into the wet ones. Gently combine everything without overdoing it. Just stop once it's all mixed evenly.

Pour in those mini M&M's, semisweet chocolate chips, and 1/4 cup of Rice Krispies. Stir softly, so you don't smash the bits. You want it all spread out in the dough but not overworked.
06 -
Scoop up the dough using 1/3 cup or an ice cream scooper. Divide the dough into 6 chunks and roll each into a ball. Give them a little flattening with your hand.
07 -
Take one marshmallow and set it on top of each flattened dough chunk. Wrap the dough around it, but let the marshmallow’s top peek through.
08 -
Grab your set-aside portion of Rice Krispies. Dip the marshmallow end of each cookie into the cereal to coat it well.
09 -
Lay the cookies across a lined baking sheet with plenty of space in between. If you’re feeling extra, add some more chocolate chips to the tops.

Bake for about 10 minutes. The cookies should be golden underneath but still look a bit soft up top. The marshmallows will puff up slightly and brown.

While the cookies are still fresh and warm, you can press a round cookie cutter or a big measuring cup gently around them to adjust their shape. Flip and swirl the gooey marshmallow around if you’d like. Sprinkle on some extra M&M’s or Rice Krispies for a fun garnish.

Leave the cookies on the tray until fully cooled before serving them.
