Oatmeal Cream Pie Ice Cream Sandwiches
The classic combination of soft oatmeal cookies and creamy marshmallow filling in a fun ice cream sandwich.
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. The marshmallow ice cream is the fun part— really creamy and taste just like marshmallows. Together it’s a winning summer dessert, perfect no matter the temperature.
baking tip:The difference between steel cut, rolled, and instant oats
Steel cut oats— The whole oat is cut into pieces which look like grains of rice. These oats take the longest to cook and typically aren’t used in baking recipes.
Old-fashioned/rolled oats— The whole oat is pressed flat during processing. These oats cook much faster than steel cut oats and are the most common oats used in baking recipes.
Quick-cooking/instant oats— These oats are precooked, dried, and pressed flat. They cook very quickly, but don’t retain much of their texture. They can be used in baking recipes, but the baking time will need to be adjusted.
Oatmeal Cream Pie Ice Cream Sandwiches
Ingredients
For the cookies:
- 1 cup unsalted butter , at room temperature (226 grams)
- 1 cup packed light or dark brown sugar (213 grams)
- ½ cup granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1 ½ cup all-purpose flour (170 grams)
- 1 teaspoon baking soda
- ½ teaspoon salt
- ¼ teaspoon cinnamon
- 3 cups quick cooking oats (265 grams)
For the ice cream:
- 1 cup whole milk (237 ml)
- 2 cups marshmallows (150 grams, about 20 large)
- 1 teaspoon vanilla extract
- 2 cup heavy cream (470 ml)
Instructions
To make the cookies:
- Preheat oven to 375°F. Line a sheet pan with parchment paper or silicone baking mat.
- 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.
- In a separate bowl combine the flour, salt, baking soda, and cinnamon. Add to the mixer and mix until just combined. Add the oats.
- 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:
- 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.
- Once chilled, the gelatin in the marshmallows may have solidified somewhat. Simply whisk until smooth and liquid once more.
- 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:
- 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.
- Serve immediately or place sandwiches in the freezer for later.
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
These cookies look freaking awesome! And I say that when you can sleep in two separate beds, you know it’s real love!
Mmm such a fun summer treat! This sounds awesome!
Thanks for this yummy sounding recipe. I LOVE oatmeal cookies, and ice cream sandwiches! Don’t think I can miss with this one!

way too much deliciousness here!
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. 😉
Love these! Oatmeal Cream Pies are one of my favorite treats! Can only imagine they’d be even better in ice cream form!
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.
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 these, Annalise! Homemade ice cream sandwiches are always the best. I definitely have to try making marshmallow ice cream!
Mouthwatering!!! Now all i can think of are these oatmeal cream pies!! YUM!
Love these Annalise!! I’m a sucker for any oatmeal cookie, sandwiched with some ice cream? Yes please!!
I love that you used marshmallow ice cream in these sandwiches – such a fun twist on the classic oatmeal cream pie!!
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. 🙂 I am completely dying over the marshmallow ice cream. I need to try it asap! Thanks so much for joining the party!
What a genius smooshy middle: marshmallow ice cream. Hopefully it will cool you off so things can heat up again *wink
why do you use less butter in your recipe? original recipe calls for 1 1/4 cup of butter…
Didn’t think it needed it all, and I was right!
These look divine! I’m like your husband, sleeping in the basement; it’s cooler and the kids can’t find me there! 🙂
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…..it 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!
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! 🙂
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? =(
Your family must be CRAZY. There is absolutely nothing wrong with ice cream every day for two weeks, or for forever. 🙂
Nothing wrong at all! =)
And now I really want to make coconut ice cream as well!! fabulous!
