One-Bowl Monster Cookies


If you thought it wasn't possible to make healthier monster cookies, think again. These peanut butter, oatmeal, chocolate chip and M&M cookies have less butter and sugar than traditional recipes, but they have just as much flavor and tenderness, thanks to more peanut butter. Even better, they're made in one bowl for easy cleanup.

Prep Time:
20 mins
Additional Time:
40 mins
Total Time:
1 hrs
2 dozen cookies


  • ¾ cup creamy natural peanut butter

  • 6 tablespoons unsalted butter, melted

  • cup packed light brown sugar

  • 2 large eggs

  • 1 teaspoon vanilla extract

  • 1 cup quick-cooking oats (see Tip)

  • ½ teaspoon baking soda

  • ¼ teaspoon salt

  • ¼ cup semisweet chocolate chips

  • cup candy-coated milk chocolate pieces


  1. Preheat oven to 350 degrees F. Coat a large baking sheet with cooking spray.

  2. Beat peanut butter, butter and sugar in a large bowl with an electric mixer until creamy. Add eggs and vanilla and beat until combined. Sprinkle oats, baking soda and salt evenly on top of the dough and beat on low speed until combined. Stir in chocolate chips. Roll level tablespoons of the dough into balls and place on the prepared baking sheet, making 12 cookies per batch. Press 3 or 4 candy-coated chocolates into the top of each cookie.

  3. Bake until barely brown on the bottom, 8 to 10 minutes. Cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely. Repeat with the remaining batter and candy-coated chocolates.


To make ahead: Store airtight at room temperature for up to 3 days.

Tip: People with celiac disease or gluten sensitivity should use oats that are labeled "gluten-free," as oats are often cross-contaminated with wheat and barley.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
