So who’s done with New Years Resolutions and ready for some sugar again??

*hand raised*

But, if you’re not, no worries. I’ve still gotcha covered: Healthy Dark Chocolate Chip Oatmeal, 100+ Weight Watchers DessertsPB Chocolate Banana Green Smoothie, Single Serve Skinny Brownie Batter Dip, and seriously a ton more!

As far as I’m concerned, I’m quite happy to have already started on my annual red velvet craze (I made Red Velvet Brookies and Red Velvet Macadamia Nut Cookies, YUM!), and I have a list of about eleventy million more recipes I’m hoping I can squeeze in between now and V-day.

But I know you’re not all Red Velvet fanatics like I am, so I thought breaking up some of the recipes with other flavors might be a good idea. …and who doesn’t love Oreos and Peanut Butter?!

This ice box comes together in about 5 minutes. Serious. However you do have to put in some wait time– that’s the hardest part. It needs to chill for a couple of hours in the fridge to soften the Oreos and then another few hours in the freezer if you like it frozen like I do (although, you could certainly just serve it right out of the refrigerator if you wanted). Either way, it needs to chill for at least 4 hours. But overnight is really best!

Peanut Butter Oreo Icebox Cake


  • 16 oz Cool Whip
  • 1 cup peanut butter (I like crunchy)
  • 16-20 Double Stuff Oreos


  1. Line a standard loaf pan with foil.
  2. Line the bottom of the pan with 8 Oreos (if you can fit more in there, go for it).
  3. Whisk together the peanut butter and the cool whip in a large bowl. Pour half of the mixture over the Oreos.
  4. Line another layer of 8 Oreos over the Cool Whip layer. Pour the remaining Cool Whip mixture over the Oreos.
  5. Optional: crumble Oreos over top, drizzle with melted peanut butter or hot fudge (or both).
  6. Cover and chill in the refrigerator for at least four hours or (preferably) overnight. If you'd like to freeze it (for easier cutting and a more ice-cream-like texture), leave it in the refrigerator for 2 hours before moving to the freezer to freeze overnight.


I recently stumbled upon this Oreo Icebox Cake recipe which recommends giving the Oreos a quick dunk in milk before layering them. This makes them even softer and looks delicious! I will definitely be trying with my next icebox cake!


**a reader emailed me and suggested freezing the cake instead! Yum!

  1. The opening pic is without a doubt my FAVORITE image I have ever seen on your site. Stunning. The contrast, the colors, it’s tack sharp, and it’s really hard to photograph frozen things and not have them melt, and get clean cuts no less through those rock hard cookies. Girl. I’ve been there. This is a stunning photo that belongs on a magazine cover. And I’m sure the recipe tastes lovely too :) pinned!!

  2. I never started, so consider me all in. Love this cake! Pinned.

  3. New Years resolutions? Bah. Bring on the sugar!

  4. I’m good with all things sugar all the time :-) I love that you added the peanut butter to this. I’ve had it with plain Cool Whip, but now all I can think about is the peanut butter goodness this must be!!!

  5. I’ve always wondered about mixing together just a few simple ingredients, sticking it in the freezer, and being able to call it an icebox cake. Intriguing! Those layers look absolutely gorgeous, I can’t wait to sink my teeth into this :)

  6. Wow!! I see this and totally forget about any resolution I ever had. Looks amazing.

  7. This makes me so happy I want to jump up and dance . . . and do cartwheels and then make and eat the entire cake!

    Ashton you have outdone yourself girlfriend. Big, big love!!!!!!!!!!!

  8. This looks delicious! I never made the sugar resolution. Just the resolution that I would bond with my treadmill more. I’m pretty much holding to that one, so all is good. Thanks for sharing this quick easy recipe :)
