- 1 ½ c. brown sugar, packed
- 2 whole large eggs
- 1 tbsp. vanilla extract
- 1 ½ c. all-purpose flour
- ½ tsp. baking soda
- 1 tsp. baking powder
- 2 tsp. kosher salt
- 1 ½ c. oats (either quick or regular)
- ½ c. M&M’s (more to taste)

How To Make Pioneer Woman Monster Cookies
- Preheat and Prep: Preheat your oven to 375°F (190°C). Line two baking sheets with parchment paper.
- Cream Butter and Sugars: In the bowl of a stand mixer or a large bowl with a hand mixer, cream the softened butter with the white and brown sugars until light and fluffy.
- Add Wet Ingredients: Beat in the eggs one at a time, followed by the vanilla extract.
- Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, baking powder, and kosher salt.
- Mix the Dough: With the mixer on low, gradually add the dry ingredients to the wet ingredients, mixing only until just combined.
- Fold in Mix-ins: Using a spatula, fold in the oats, M&M’s, chopped pecans, chocolate chips, and peanut butter chips.
- Add Cereal: Gently stir in the Rice Krispies last, being careful not to crush them too much.
- Scoop and Bake: Drop rounded spoonfuls of dough onto the prepared baking sheets, about 2 inches apart. Bake for 10–12 minutes, or until the edges are golden brown but the centers are still soft.
- Cool the Cookies: Let the cookies cool on the baking sheet for 2–3 minutes to set up before transferring them to a wire rack to cool completely.

Recipe Tips
- How do you keep the cookies chewy? The most important step is not to overmix the dough after you add the flour. Mix only until the flour streaks disappear. Overmixing develops gluten and results in a tougher, cakier cookie.
- How do I keep the cookies from breaking? These cookies are loaded with goodies and can be delicate when hot. Letting them cool and set on the baking sheet for a few minutes before moving them is a crucial step to prevent them from falling apart.
- Can I change the mix-ins? Absolutely! Monster cookies are meant to be customized. Feel free to swap the pecans for walnuts, use different types of chocolate chips, or add other candies like Reese’s Pieces.
- Why add the Rice Krispies last? To maintain their signature crunch, the Rice Krispies should be folded in very gently at the very end. If you mix them too vigorously, they will get crushed and lose their texture.
What To Serve With Monster Cookies
These hearty, all-in-one cookies are a perfect treat on their own. They are best served with:
- A tall glass of cold milk
- A hot cup of coffee or tea
- A scoop of vanilla ice cream for an epic cookie sandwich
How To Store Monster Cookies
- Room Temperature: Store the completely cooled cookies in an airtight container at room temperature for up to 4 days.
- Freeze: You can freeze the cookie dough balls on a baking sheet until solid, then transfer them to a freezer bag. Bake from frozen, adding 2-3 minutes to the baking time.

They get their name because they are like a Frankenstein’s monster of cookies, made up of a little bit of everything—oats, peanut butter, chocolate chips, and candy. They are also often made in a monstrously large size.
Can I make the dough ahead of time?
Yes, the cookie dough can be made and chilled in the refrigerator for up to 3 days before baking. This will also help prevent the cookies from spreading too much.
Can I make these gluten-free?
