What Ingredients are in Peanut Butter M&M Cookies?

Most of these ingredients can be found in your pantry or local grocery store. The M&Ms are the star of the show, so make sure to grab a big bag of them!

  • Butter: Unsalted butter that has been softened to room temperature to ensure it mixes well with the other ingredients.
  • Light brown sugar: Light brown sugar adds a caramel-like sweetness and helps keep the cookies moist.
  • White sugar: Granulated white sugar adds sweetness and helps the cookies spread out while baking.
  • Eggs: Large eggs are used to bind the ingredients together and help the cookies rise.
  • Vanilla extract: Vanilla extract adds flavor and aroma to the cookies.
  • Creamy peanut butter – Creamy peanut butter is the star ingredient and adds richness and flavor to the cookies.
  • All-purpose flour: All-purpose flour is used to provide structure and texture to the cookies.
  • Baking soda: Baking soda helps the cookies rise and creates a light texture.
  • Salt: Salt enhances the flavor of the cookies and balances the sweetness.
  • M&Ms: M&Ms are added to the cookie dough for their chocolatey flavor and fun, colorful appearance.

Pro Tips:

  • Use room temperature butter. Softened butter will cream more easily with the sugar, resulting in a smoother cookie dough.
  • I don’t recommend crunchy peanut butter but you can use whichever kind of peanut butter you prefer.

How to Make Peanut Butter M&M Cookies

Peanut butter lover and chocolate lover unite! Here’s how to make this peanut butter cookie recipe.

  1. Blend: Cream the butter and sugars together until light and fluffy.
  2. Mix: Add in the eggs, vanilla extract, and peanut butter, and mix until well combined.
  3. Combine: In a separate large bowl, whisk dry ingredients. Then gradually mix into the wet ingredients. Fold in the M&Ms.
  4. Bake: Scoop the cookie dough balls and place them onto a lined baking sheet. Bake until the edges are golden brown.

Pro Tips:

  • Once you add the flour mixture, mix the dough until just combined. Overmixing can result in tough cookies.
  • Press a few extra M&Ms onto the top of each cookie dough ball before baking to make them extra pretty and flavorful.
  • For best results, prepare cookie sheet with parchment paper, non-stick foil, a baking mat, or cooking spray.
  • Use a stand mixer or electric mixer to save your arm the workout.

Can Dogs Eat Peanut Butter M&M Cookies?

While peanut butter is safe for dogs to eat, a chocolate m&m is not. 

Chocolate can be toxic to dogs, so it’s best to keep these cookies away from your furry friends. 

If you want to give your dog a peanut butter treat, try making some homemade peanut butter dog biscuits instead!
