You are going to love the texture of these big, soft, buttery cookies.

The dough itself has a melt-in-your-mouth kinda action and the big peanut M&M’s gives crunch appeal.

Pretty much a match made in heaven.

But the softness all comes down to the cooking time.

If you cook these babies for too long they will no longer be big softies.

How to Make Peanut M&M Cookies

First, line a cookie tray with a baking sheet and preheat your oven to 350F.

Melt the butter in the microwave until it turns into liquid (around 30-40 seconds should do it). In a large mixing bowl, add the butter, brown sugar and white sugar and beat together until it reaches a creamy consistency and pale color.

Add in the egg and vanilla extract then beat until the egg is just mixed in. Be careful not to overbeat in this step because it will make the cookie dough become stiff.

Next, sift in the flour, baking soda and salt into the mixture. Grab a wooden spoon or spatula and mix the ingredients together until they reach a crumbly texture. Now you’ll want to use your hands to knead the dough in the bowl until it’s well combined into a ball. Finally, add the peanut m&ms to the dough and knead until they’re all mixed in.

Time to start baking! Roll the dough into 12 balls and place them evenly spaced on the cookie tray not too close together. Cook them in the oven for a total time of 10-11 minutes, they should be a pale color with just a touch of tan when taken out of the oven. It’s very important not to over bake!

Allow the cookies to cool for 30 minutes on a tray and then they’re ready to devour!

How Long Will They Keep?

Peanut m&m cookies will last for a week when kept in a dry cool place in an airtight container.
