King Arthur Monsters with Flour

Jun 27, 2012 · Modified: Jan 2, 2023 by Anna · This post may contain affiliate links · 17 Comments

Monster Cookies are one of my all-time favorites, and the number of recipes on this blog attests to that. There's just nothing bad about Monsters -- at least the cookie type.

What Are Monster Cookies?

Monsters are very large oatmeal peanut butter cookies with loads of candy including chocolate chips and M&Ms. Most Monster recipes do not call for flour and are basically gluten-free, but not all. For instance, King Arthur Flour's recipe for Monster Cookies does have a bit of flour.

Another nice thing about Monster cookies is they can be made in one bowl and do not require an electric mixer. They are one of the most relaxing cookies to bake, and if I lived in a country that had a quota on how many cookie recipes a person could own, Monster Cookies would be among my select few. They have everything!

Below is a recipe from The King Arthur Flour Cookie Companion: The Essential Cookie Cookbook (King Arthur Flour Cookbooks). I usually scale it down and make small batch monster cookies, but a neighbor just brought home a new baby so I made their family a large batch using every kind of baking chip and candy in the house including tiny M&Ms.

Monster Cookies Without Flour

If you'd rather try some more traditional Monsters, I recommend Ann Romney's Oatmeal Peanut Butter M&M Cookies. They were contenders in Family Circle's ever popular Presidential Cookie Bake-Off, and in the end they lost to Michelle Obama's Black & White Chocolate Chip.

Ingredients
 

  • 3 large eggs
  • 1 cup regular or organic granulated sugar (200 grams)
  • 1 cup packed light brown sugar (220 grams)
  • 2 teaspoons baking soda
  • 1 teaspoon salt
  • 1 teaspoon corn syrup or maple syrup
  • 1 ½ teaspoon vanilla extract
  • 1 ½ cups peanut butter (mainstream sweetened type)** (390 grams)
  • ½ cup unsalted butter, melted and cooled (114 grams)
  • ½ cup all-purpose flour (63 grams)
  • 4 ½ cups old-fashioned rolled oats
  • ½ cup dark chocolate chips
  • ½ cup butterscotch chips
  • ½ cup white chips
  • ½ cup mini candy coated chocolates M&Ms

Instructions
 

  • Preheat the oven to 350 degrees F now, or wait and do it a little later in the process. The dough will need to sit for 30 minutes. Have ready two or three greased or nonstick foil lined baking sheets.
  • In a large mixing bowl, stir together the eggs, both types of sugar, baking soda, salt, maple syrup and vanilla. Stir in the peanut butter and melted butter. When mixed, add flour and stir until blended. Lastly, stir in the oats, all the different chips and the candies.
  • Let the dough sit for 30 minutes so that the oats can absorb some moisture. At this point, you might also want to preheat the oven.
  • Using a quarter cup measure, scoop up dough and arrange mounds about 4 inches apart on the sheets. Press the tops down slightly to flatten somewhat (you want even mounds rather than spheres). Bake at 350 degrees F for 12 to 15 minutes or until cookies appear set and lightly browned around the edges. Let cool on the baking sheet for 5 minutes, then transfer cookies to a wire rack to cool.

Notes

The recipe is supposed to make 26 cookies, but I usually get 22-24.  For the peanut butter, it's best to use a sweetened kind like Jif or Skippy.  Using unsweetened peanut butter makes the cookies a little too chewy.

    These cookies are awesome! Sturdy, crisp outside, tender inside and packed with lots of goodies. I didn't have white or butterscotch chips, but was happy with just chocolate chips and m&m's I also threw in some peanut butter chips too. I will be making these again soon. May even throw in some chopped peanuts. Or better yet peanut m&m's!

    Sarah, thanks for the review! I might make another batch for our block party this week. One thing I noticed was the batch I accidentally over-baked was crunchy and delicious despite being a little too brown. Since I like crunchy cookies, I may make another batch and try baking at a lower temperature (325) for a longer time. Hopefully slower and lower will make them crunchier without being too brown. They're good baked at 350 too, but I still want to test at 325.

    Made a half batch of the recipe last night. SO GOOD!!! We didn't have butterscotch so we added heath crunchies instead. For a half batch, we used one egg an the egg white of another egg. it made about 19 cookies. I guess my cookies aren't nearly as large as the recommended size, but they were pretty big nonetheless. Delicious, will definitely make again!

    I am going to give both recipes a try.

    Michelle Obama's recipe has to have a typo in it - no way it would need 2 cups of butter/shortening. It is just the Tollhouse recipe with different chips in it.

    I've never made or had Monsters either! Oh, and I just had to Google Michelle Obama's cookies too, of course...

    I looked and my recipe does call for corn syrup. I wouldn't have thought to put maple syrup in but now I'm wondering about that or Lyle's Golden syrup, or maybe even honey?

    I love the bake-off! I think these may replace my previous favorite (Cindy McCain's).

    Who doesn't love monster cookies!? I haven't made them in years. I wish I had more excuses to bake! I'm going to go look at my recipe. I don't remember any kind of syrup in the recipe. Do you taste it?

    For some strange reason, I already had M&M's in the cupboard (that weren't eaten with the already open bag, go figure!) 😉

    I love your humor, Anna. Your neighbor brought home a baby (hers). I laughed!

    And I know why mine turned out better (jk!)--I used Skippy Natural instead of Jif. Not sure why, but I'm a Skippy PB person. Funny I say that though, because I only buy all natural brands for me that are just peanuts. But I buy Skippy for the rest of the fam (and for baking). Your cookies do look good.

    I admit, I had to run to the store for some M&Ms.

    Caralyn, I'd be curious to see your recipe.

    oh my gosh I LOVE monster cookies! they're so good! my recipe doesn't have candy in them though -- so they're *almost* healthy enough to eat for breakfast! haha

    These sound great, and I've got everything on hand except the M&Ms!
