Monster Cookie Dough Fudge Bars (Gluten-Free!)

Monster Cookie Dough Fudge Bars

My husband is very romantic, but not in the ways people might consider stereotypical. He’s never stood outside my window with a giant boom box blasting “In Your Eyes,” nor has he borrowed his friend’s dad’s Ferrari to impress me as we cruise around downtown Chicago on a school day…

Wait. I’m confusing real life with John Hughes movies again.

Yesterday, my husband installed a much better spam filter for my site. You know, so I can stop getting comments like, “There are many women body types and depending on your shape, you will definitely get the best design that fits you perfectly.”

Say what? And that’s one that makes more sense than most. Most are not in English.

So yeah, my husband has filtered my Spam. And in return, I’ve made him another gluten-free treat. A really fun one, if I do say so myself!

Monster Cookie Dough Fudge Bars

These are a riff on one of the best cookies out there, the monster cookie. If you’re not familiar, a monster cookie is a peanut butter oatmeal cookie with M & Ms and chocolate chips. Sometimes people go crazy and put in more mix-ins. Nutty! Anyway, this bar is like monster cookies, but it’s a gluten-free, egg-free cookie dough made from oat flour!

And the top is made of…drum roll, please…PEANUT BUTTER FUDGE. Yep, you read that right. Cookie dough topped with fudge. Can we please have a moment of silence? Wait. I think I just heard chewing. Oh yeah, that’s me.

Oat flour tends to make recipes more moist, so the only catch to these bars is that they have to be kept chilled. Otherwise, they’ll be too sticky to handle. But they taste perfect. And there are little oats poking out of them, so you’ll feel super healthy eating them.

Remember to use gluten-free oats and oat flour. Otherwise, yeah. This recipe ceases to be gluten-free!

My husband deserves a lot more than just these bars, but they’re a start. Maybe I can find some really good seats at the next Orioles game to top it all off and win wife of the year.

Try these out! They’re no-bake and perfect for this hot weather!


Cookie Dough Layer:

  • 1/2 cup butter, softened to room temperature
  • 3/4 cup firmly packed brown sugar
  • 1 teaspoon vanilla
  • 2 cups oat flour
  • 1/4 cup rolled oats
  • 14 oz. can sweetened condensed milk (I used fat-free)
  • 1/2 cup mini chocolate chips
  • 1/2 cup mini M & Ms


Fudge Layer:

  • 1 bag peanut butter chips
  • 14 oz. can sweetened condensed milk (I used fat-free)
  • 2 teaspoons vanilla



In the bowl of a stand mixer, cream the butter and brown sugar until light and fluffy. Add in the vanilla and mix again. Pour in oat flour and condensed milk alternately, beating until thoroughly combined.

Stir in the mini chocolate chips and mini M & Ms. Press the mixture into the bottom of a 9 x 13-inch greased pan.

Next, make the fudge layer. Using a microwave-safe bowl, heat the condensed milk and peanut butter chips for 2 minutes. Stir until smooth, add the vanilla, and stir again. Pour the fudge layer over the cookie dough layer, being sure to spread the fudge to the edges of the pan.

Refrigerate for 2 hours. When the cookie dough fudge is firm, cut into small squares and serve! Store covered in the refrigerator for up to one week.


I fulfill many roles in life: wife, mother, teacher, everlasting learner. This site is dedicated to one role that expresses my creativity in ways that I find consistently challenging and rewarding: baker. Inventing new ways to enhance food, especially if that food involves chocolate or peanut butter (or both!), is a passion of mine. I look forward to sharing my ideas with you.
