One-Bowl Monster M&M Cookies — The Snack That Holds a Toddler-Plus-Pregnancy Afternoon Together

Late May. Brayden is one hundred and thirty-eight weeks old. The pregnancy is at thirty-eight weeks. Tuesday last week was the kind of Tuesday where Brayden refused his afternoon nap and Mama was at the cafe in Sapulpa (she had driven down for the day to check in on Cody and the cafe’s expansion construction) and Dustin was on a long Tuesday at the shop. I needed a small fast win to hold the afternoon together. The win: a sheet pan of one-bowl monster M&M cookies.

The one-bowl monster M&M cookies are a small fast-easy cookie — flour, oats, brown sugar, butter, an egg, baking soda, salt, peanut butter, M&M’s, chocolate chips. Everything goes in one bowl in order, stirred together by hand or with a small spatula, scooped onto a sheet pan, baked at 350 for twelve minutes. No mixer, no chill, no creaming. The cookies come together in about fifteen minutes from start to oven.

The technique question on a one-bowl cookie is the order of operations. The wet ingredients go in first (butter melted, egg whisked in, peanut butter folded in). The dry ingredients go in second on top of the wet, with the leavening (baking soda) being whisked into the flour before the flour goes in. The mix-ins (M&M’s, chocolate chips) go in last with the smallest amount of stirring.

Sunday I made the cookies again for a less-tired reason — Brayden had asked specifically for them all weekend after the Tuesday-afternoon success. He stood on the small step-stool at the kitchen counter and “helped” with the small stirring. Mama (who had returned from Sapulpa) watched from the kitchen counter.

One-Bowl Monster M&M Cookies

Prep Time: 15 min | Cook Time: 11 min | Total Time: 26 min | Servings: 24 cookies

Ingredients

• 1 cup (2 sticks) unsalted butter, softened
• 3/4 cup granulated sugar
• 3/4 cup packed brown sugar
• 2 large eggs
• 2 teaspoons vanilla extract
• 2 1/4 cups all-purpose flour
• 1 teaspoon baking soda
• 1/2 teaspoon salt
• 1 1/2 cups M&M candies (plain or peanut)
• 1 cup old-fashioned rolled oats
• 1/2 cup semi-sweet chocolate chips (optional)

Instructions

1. Preheat the oven. Heat your oven to 375°F. Line two baking sheets with parchment paper or silicone baking mats and set aside.
2. Cream butter and sugars. In a large bowl, beat the softened butter, granulated sugar, and brown sugar together with a hand mixer or sturdy wooden spoon until light and fluffy, about 2–3 minutes.
3. Add eggs and vanilla. Beat in the eggs one at a time, then stir in the vanilla extract until fully combined.
4. Mix in dry ingredients. Add the flour, baking soda, and salt directly to the same bowl. Stir until just combined — don’t overmix.
5. Fold in the mix-ins. Gently fold in the rolled oats, M&M candies, and chocolate chips if using, distributing them evenly throughout the dough.
6. Scoop the dough. Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart. Press a few extra M&Ms onto the tops for looks if you like.
7. Bake. Bake for 9–11 minutes, until the edges are just set and lightly golden. The centers will look slightly underdone — that’s perfect. Do not overbake.
8. Cool on the pan. Let the cookies rest on the baking sheet for 5 minutes before transferring to a wire rack. They firm up as they cool and stay wonderfully chewy.
