Rainbow Fudge Cookie Bars

 Happy Birthday to my sweet and handsome hubby, Michael! These Rainbow Fudge Cookie Bars are the perfect birthday treat. Yes?

Rainbow Fudge Cookie Bars recipe with 4 simple ingredients! Soft, chewy cookies with a layer of fudge and candy!

Unfortunately, life as a food blogger can be pretty weird. And if you’re a family member to a food blogger? Well, I’m so sorry, haha!

See, if you follow me on instagram, you’ll see that two months ago I was baking with pumpkin. Two weeks ago I was baking with peppermint. Yesterday I shared another Christmas photo on instagram, of a recipe I made in my kitchen. I know. We’re like Walmart hauling out our holiday stuff way too soon.

And birthdays? Well, they aren’t always as they seem on the blog.

For instance, these Rainbow Fudge Cookie Bars would make a lovely afternoon treat for a birthday! And since today is my husband’s birthday, I’m sharing this recipe here on the blog.

But in real life, we ate these cookie bars weeks ago. They were delicious.

Tonight, for my husband’s REAL birthday, we are having one of his favorite dinners: Slow Cooker Barbacoa. For dessert…I hate to admit it (hiding my head in shame) but we are going to Dairy Queen for ice cream. I know. I should just quit food blogging. Since I am mainly a dessert blogger you would think I’d have some extravagant, DELICIOUS, over the top treat for my husbands birthday.


But to be fair, he wanted to go out for ice cream. Hmmm….what does that say about me and my treats?? Let’s just not read into it, k?

Instead, how about enjoying a batch of these Rainbow Fudge Cookie Bars in honor of his number (cough cough) birthday.

Did I mention yet that this recipe is 4 easy ingredients? I used refrigerated cookie dough as the base (don’t judge, don’t hate…just enjoy the simplicity). When the cookies came out of the oven, I whipped up the fudge layer by microwaving sweetened condensed milk with chocolate chips, until smooth and creamy. Spread that over the cookies and sprinkle with mini m&m baking pieces!

There you have it folks. My “how to” on being a successful blogger: refrigerated cookie dough and the microwave.

Kidding. Sorta.

  1. Hi, I found this on FoodGawker and was hoping I could get your permission to post the recipe on my instagram recipe page (@foodie_recipes) as it looks delicious! I will tag you in the photo and put your website address on the post! Hope this is okay, thanks 🙂 x

  2. I don’t have a problem with refrigerated cookie dough – these look fantastic! Happy birthday to your husband!

  3. I won’t judge you for using refrigerated cookie dough if you ignore my use of cake mixes and cool whip… I love the scattering of mini M&M’s on the top and the fudgy middle layer will go over well here:) Don’t feel bad; my husband would’ve picked a store-bought angel food cake with a tub of frosting smeared on it. His mom’s creation, not mine!

  4. Love these bars, the colors, so bright and cheery and perfect! Pinned.

    Birthdays. As a dessert blogger, you’d think that when a family member has a bday I’d be the first one there with a big gorgeous cake? No. Let’s open my freezer and see what frozen dough balls I can pop in the oven and bake. LOL And I was already starting with pumpkin recipes a couple months ago too and Xmas stuff…red velvet is on my agenda next week. LOL

  5. I love that these are so simple, yet fabulous looking!!! That 2 ingredient microwave fudge is a favorite here too! Happy birthday Michael! And enjoy that ice cream…that would be my hubby’s choice too! LOL!

  6. Do not read into it at all! I have the same problem. I think my family is just spoiled with the homemade stuff and they yearn for processed, packaged food.
    I’ll eat this any day! Nothing beats fudge on cookie bars, especially with M & Ms.

  7. Happy Birthday to your hubby! And mine would always pick oreo ice cream over the fanciest cake, so I say, follow the bday boy’s wishes!
