These monster chocolate M&M cookies are chocolatey sensations. Their crisp edges–thanks to the addition of corn flakes!–chewy centers, and monstrous size make them a kid’s dream come true. (Okay, an adult’s dream, too.)
We call these monster chocolate M&M cookies “dishpan cookies” at my house because if you make the whole recipe, you need a dishpan to mix all the ingredients (or a very large bowl). These cookies traveled with my kids on many team trips and were always “winners.”–Pat Sinclair
We Interrupt This Recipe…
Put down that wooden spoon. The New York Times just reported that this Sunday’s Super Bowl XLVI will introduce yet another animated M&Ms character: Ms. Brown. The sixth member of the melts-in-your-hands-not-in-your-mouth cast, Brown will join Yellow, Orange, Red, Green, and Blue. Look for her during the first quarter commericals. (Are we the only ones who’re a little giddy about this?!)
Monster Chocolate M&M Cookies
- 3 1/2 cups all-purpose flour
- 1/2 cup unsweetened cocoa
- 2 teaspoons baking powder
- 2 teaspoons baking soda
- 1 teaspoon salt
- 2 cups (4 sticks) butter softened
- 2 cups granulated sugar
- 2 cups firmly packed brown sugar
- 2 teaspoons vanilla extract
- 4 large eggs
- 2 cups quick-cooking oats
- 2 cups cornflakes (after measuring the cornflakes, crush them lightly)
- 2 cups M&Ms, semisweet chocolate or butterscotch chips, or a combination
Make the cookies
- Heat oven to 350°F (180°C) with oven rack in middle position. Line 2 baking sheets with parchment paper or Silpat.
- Mix the flour, cocoa, baking powder, baking soda, and salt together in really, really, really large bowl or a dishpan.
- Beat the butter, granulated sugar, and brown sugar in bowl of a mixer on medium-high speed until creamy, scraping down sides of bowl once or twice. Add the vanilla and eggs and mix well.
- Reduce the mixer speed to low and add the flour mixture. Scrape down the sides of the bowl and beat just until a dough forms. Scrape the dough back into the very large bowl. Dump in the oatmeal, corn flakes, and M&Ms or chips and stir with a spoon until combined.
For jumbo cookies
- Using a 1/4 cup measure or ice cream scoop, drop the dough onto the baking sheets, making 6 cookies on each cookie sheet. Bake 15 to 20 minutes, or until set in the center and edges are lightly browned. For softer cookies, reduce baking time slightly. The cookies will still look a little moist in the center. Cool cookies 1 minute on the cookie sheets and then place them on wire cooling racks. (Store the cookies loosely covered at room temperature.)
For normal cookies
- Drop 1-tablespoon blobs of dough onto the baking sheets, spacing them 2 inches apart. Bake 10 to 13 minutes, or until set in the center and edges are lightly browned. For softer cookies, reduce baking time slightly. The cookies will still look a little moist in the center. Cool cookies 1 minute on the cookie sheets and then place them on wire cooling racks. (Store the cookies loosely covered at room temperature.)
Recipe Testers’ Reviews
Not only did the kids approve of these monster chocolate M&M cookies, but I actually HAD to hide them. If I hadn’t, we would have had three girls with big tummy aches. These are very easy to make, and the girls had fun making them with me. We used half chocolate chips, half M&M’s. The best part is that my daughters are not usually fans of oats. I think next time I will actually double the recipe and freeze the dough, so to always have some available.
I just finished baking these monster chocolate M&M cookies, and what a fun cookie recipe it is. I was skeptical about grabbing a “very large bowl” until I mixed the butter and sugar in my extra-large stand mixer. Once the flour mixture was in, the mixing bowl was pretty full.
Scraping the batter into a larger bowl gave me the room to add the oatmeal, corn flakes, and candy. I chose M&M’s, mini peanut butter cups, and chocolate chips.
The cookies spread a bit while baking, and it is difficult to tell when the edges are brown with the chocolate-colored cookie, but 15 minutes was perfect for the monster size, and 12 worked for the smaller cookie.
I wish I could say how many the recipe produced, but they were being devoured as they emerged from the oven. They’re crispy, crunchy, and lightly sweet. The corn flakes add a unique texture and pleasant flavor to the cookies. They’re a snap to make, and even easier to eat.
I made half a batch of these monster chocolate M&M cookies. It has an even number of eggs, so halving it worked great. The dough came together very quickly and easily. I made the “normal”-sized cookies and baked them for about nine minutes, noting the author’s option for a softer cookie.
The cookies spread thin and flat but remained chewy and soft after cooling. The oats and cornflakes add a little texture but don’t distract from the mellow chocolate flavor of this cookie. I added semisweet chips but would love to try the butterscotch next time for a little more contrast.
I had six teenage boys here, and the cookies were gone quickly, so next time I may have to make the whole batch.
