The classic combination of soft oatmeal cookies and creamy marshmallow filling in a fun ice cream sandwich.

Oatmeal Cream Pie Ice Cream Sandwiches

Not only is the summer heat this year relentless, but it’s trying to destroy my marriage. Okay, not really, but it does have us sleeping in separate bedrooms.

My husband prefers to sleep in the guest bed in the basement where it is cooler, while I stay upstairs in our room because the bed is more comfortable. Before bed we kiss each other goodnight and head our separate ways. It’s terribly unromantic.

But our summer heat wave does have it’s benefits, like ice cream for breakfast, lunch, and dinner. I’ve done it, and I am not ashamed. I’ve been creating all sorts of fabulous frozen treats this year and these oatmeal cream pie ice cream sandwiches is one that I’m quite fond of.

The cookies don’t quite taste like the Little Debbie classic (probably because they’re made with real ingredients), but they are the best oatmeal cookies I’ve ever baked. Seriously.ย The marshmallow ice cream is the fun partโ€” really creamy and taste just like marshmallows. Together it’s a winning summer dessert, perfect no matter the temperature.

Rolled Oats vs. Quick Cooking Oats

You’ve seen them both at the grocery store and have had different recipes call for each, so what is the difference?

Quick cooking oats are rolled oats that have been broken up a bit, which makes the cooking process faster. To make quick cooking oats, simply pulse rolled oats in a food processor a few times.

Oatmeal Cream Pie Ice Cream Sandwiches
The classic combination of soft oatmeal cookies and creamy marshmallow filling in a fun ice cream sandwich.
Yield: About 3 dozen cookies, 1½ dozen ice cream sandwiches
  • For the cookies:
  • 1 cup (226 grams) unsalted butter, at room temperature
  • 1 cup ( grams) brown sugar
  • ½ cup sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1½ cup (170 grams) all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ¼ teaspoon cinnamon
  • 3 cups ( grams) quick cooking oats*
For the ice cream:
  • 1 cup (237 ml) whole milk
  • 2 cups (150 grams) marshmallows, about 20 large
  • 1 teaspoon vanilla extract
  • 2 cup (470 ml) heavy cream
To make the cookies:
  1. Preheat oven to 375 degrees F. Line a sheet pan with parchment paper or silicone baking mat.
  2. In the bowl of a stand mixer fitted with a paddle attachment, beat the butter and sugars together until pale and creamy. Add the egg and vanilla and mix until combined.
  3. In a separate bowl combine the flour, salt, baking soda, and cinnamon. Add to the mixer and mix until just combined. Add the oats.
  4. Shape into 1-2 tablespoon sized balls and place on prepared sheet pan. Bake until edges are golden but middle is still soft, about 10 minutes. Cool completely.
To make the ice cream:
  1. Pour the milk into a medium saucepan and place over medium heat. Add the marshmallows and stir frequently as they melt into the milk. Once smooth, remove from heat and add vanilla. Pour mixture into a medium bowl and add heavy cream. Chill completely.
  2. Once chilled, the gelatin in the marshmallows may have solidified somewhat. Simply whisk until smooth and liquid once more.
  3. Freeze in an ice cream machine using manufacturer's instructions. Scoop into a bowl or container and place in the freezer for several hours to firm up.
To assemble the ice cream sandwiches:
  1. Let the ice cream come to room temperature for about 10-15 minutes so that it's easier to work with. Place a scoop of ice cream on one cookie and place another on top. Press down gently to sandwich to two together.
  2. Serve immediately or place sandwiches in the freezer for later.
*Note: Substitute rolled oats by pulsing them a few times in a food processor to break them up.

  1. These look great and sooo refreshing, even if I’ll probably make them with another ice cream flavor since I don’t like marshmallows…
    Btw, I’ve always dreamed of eating ice cream for breakfast, lunch and dinner in the same day!

    xo, Elisa

    My husband and I aren’t terribly romantic either. We usually have a pillow separating us in bed. He can be a bit of a bed hog, so I have to mark my territory. ๐Ÿ˜‰

    Love these! Oatmeal Cream Pies are one of my favorite treats! Can only imagine they’d be even better in ice cream form!

  7. I do not think there is oatmeal cookie sandwich I have not been in love with. While I might be in winter I can see myself with a batch of these and eating them with a warm latte.

  8. Your ice cream sandwiches look delicious, Annalise! Love that you used soft oatmeal cookies and marshmallows in your ice cream. Talk about soft and squishy (in the best of ways) goodness! Love this Frozen Treats Week blog party. Thanks for sharing!

    I love that you used marshmallow ice cream in these sandwiches – such a fun twist on the classic oatmeal cream pie!!

  13. Deborah says:

    Haha – my husband and I are sleeping in 2 separate beds right now, too, because the bed is too small for us both to be comfortable. ๐Ÿ™‚ I am completely dying over the marshmallow ice cream. I need to try it asap! Thanks so much for joining the party!

  14. What a genius smooshy middle: marshmallow ice cream. Hopefully it will cool you off so things can heat up again *wink

  15. Paula D. says:

    why do you use less butter in your recipe? original recipe calls for 1 1/4 cup of butter…

  16. These look divine! I’m like your husband, sleeping in the basement; it’s cooler and the kids can’t find me there! ๐Ÿ™‚

  17. Sounds absolutely fantastic and I keep finding all of these recipes that I am going to need an ice cream maker for and I still don’t have one… saddens me to no end so until I come up with the extra cash, this will be in my super stash of wanted frozen yum yum recipes. Thanks for sharing! Oh Oatmeal cookies have ALWAYS been my favorite cookie and the marshmallow ice cream sounds fantabulous!

    • Annalise says:

      While it’s possible to make ice cream without the machine, it definitely makes it much easier and much better end product. Maybe an item to add to your next gift wishlist?? Thanks for the comment! ๐Ÿ™‚

  18. Stephanie says:

    I get in trouble if I want more than ice cream a day. In fact, I got in trouble for having ice cream every day for two weeks straight! Can you adopt me into your ice cream loving family? =(

  19. And now I really want to make coconut ice cream as well!! fabulous!
