Set the oven's temperature to 350 degrees Fahrenheit. Use Silpat baking mats or parchment paper to line two baking sheets.

Cream the butter, brown sugar, and sugar in the bowl of a stand mixer using the paddle attachment until it is light and fluffy.

Beat in the eggs one at a time, followed by the peanut butter, vanilla, baking soda, and salt, beating everything together until smooth.

Then add the micro M&Ms and chocolate chips after combining the oats and the addition.

Place 2- to 3-tablespoon-sized mounds of the dough, spaced at least 2 inches apart, onto the prepared baking sheets.

The cookies should be baked for 12 to 15 minutes, then they should be taken out of the oven and allowed to cool for 5 minutes on the baking sheets before being moved to a rack to finish cooling.
