Recreate the iconic Little Debbie's Oatmeal Creme Pies with a healthier twist, using a few special ingredients to give authentic flavor without the added sugars or carbs. These soft, chewy cookies sandwich a creamy filling, delivering nostalgia in every bite.

Feel like a kid again with the nostalgic taste of Little Debbie’s with this recipe for soft and chewy keto oatmeal cream pies. Just like my other keto cookie recipes, like my pumpkin whoopie pies, chewy peanut butter cookies and (my favorite) keto chocolate chip cookies, you won’t miss the sugar filled originals with these low-carb versions of the classics. Two homemade oatmeal cream pies stacked on each other with a bite taken out of the top sandwich cookie. A box of Little Debbie's Oatmeal Creme Pies is in the background.

What makes them keto:

  • No rolled oats – These almond flour based sandwich cookies mimic the beloved oat flavor without actually using rolled oats. The secret lies in incorporating oat fiber, an insoluble fiber found in oat husks. Adding oat fiber to the almond flour gives our keto oatmeal cookies that hint of oat flavor without adding any additional carbohydrates since oat fiber is ZERO CARBS!
  • Molasses flavor without the sugar – Instead of molasses, which has sugar, we use a molasses flavor extract.
  • Perfectly sweetened cream filling – The cream filling stands out with its thick and creamy consistency. Unlike many keto frostings that can become overwhelmingly sweet due to an excess of powdered sugar-free sweeteners, this recipe strikes the right balance. By using a specific brand of sugar-free sweetener and oat fiber, the result is a filling that’s perfectly sweetened, with an added depth of oat flavor and a desirable texture.
  • Marshmallow cream – Do you think the Little Debbie’s version has a hint of marshmallow in the cream filling? Me too. Instead of using marshmallow fluff, a few drops of toasted marshmallow flavoring is added to the filling to give a subtle marshmallow undertone.
  • Only 1.4 g net carbs – Using the ingredients above along with a combination of brown sugar free sweetener and granulated sugar free sweetener, we are able to keep the carbohydrates very low.

Step by Step Instructions

Step by Step Instructions

1
Preheat oven

Preheat oven to 325˚F. Line a baking sheet with parchment paper and set aside.

2
Combine wet ingredients

In a large bowl, cream together softened butter, brown sugar-free sweetener and granulated sweetener. Mix until creamy. Stir in molasses flavoring, vanilla extract and eggs. Set aside.

Tip Use a brown sugar substitute that can pack and has moisture to it.
Ingredients for this step
  • 1 cup unsalted butter, softened to room temperature
  • 3/4 cup packed browned sugar free sweetener
  • 1/3 cup granulated sweetener
  • 1 teaspoon molasses extract
  • 1 teaspoon vanilla
  • 2 eggs
3
Mix dry ingredients.

In a medium bowl, whisk together almond flour, oat fiber, baking soda, salt and cinnamon.

Tip Use super fine blanched almond flour.

Scoop the dough

Using a 1.25 inch cookie scoop, place balls of cookie dough onto the prepared baking sheet, spacing about 1 1/2 inches apart.

Tip If you don't have a cookie scoop, pinch off dough and roll into a 1 inch ball. Or add to a piping bag and pipe out cookie dough. No need to flatten cookies, although it won't hurt if you do.
6
Bake

Bake in the oven at 325˚F for 9-10 minutes or until the edges start to turn golden. Remove from the oven and let the cookies sit on the cookie sheet for several minutes until you can easily slide a spatula underneath. Then transfer to a wire rack to continue cooling.

Tip The tops of the cookies may look underdone and will be soft to the touch.
7
Cream filling

In a large bowl, cream butter with an electric mixer until fluffy. Slowly mix in sugar-free sweetener until combined. Add oat fiber, nut milk or cream, vanilla extract and marshmallow flavoring if using. Continue mixing until light and fluffy.

Tip Double the cream frosting if you love extra filling in your cookies.
Ingredients for this step
  • 1 cup unsalted butter, softened to room temperature
  • 1 1/2 cup sugar free sweetener (use recommended brand above)
  • 1 tablespoon oat fiber
  • 1 tablespoon nut milk or cream
  • 1 teaspoon vanilla
  • 1 1/2 droppersful marshmallow flavoring, optional

Make sandwich cookies

Scrap frosting into a piping bag and pipe swirls of filling on the underside of one cookie. Place a second cookie on top.

Are oats keto?

Rolled oats are not keto friendly because they are high in carbs. One cup of dry rolled oats has 55 grams of carbohydrates! That’s almost twice the recommended daily carb limit for the keto diet.

The keto replacement for oats

Since we can’t have oats or oatmeal on the keto diet, to get around that use oat fiber. Oat fiber is a zero carb finely milled insoluble fiber that comes from the oat husk. Using oat fiber, you can get the oat flavor without the carbs! It also helps to enhance the texture and bulk up baked goods. Don’t confuse oat fiber with oat flour. It’s not the same. Oat flour is finely ground rolled oats into a flour consistency, so it still contains carbs.

Tricks to get sandwich cookies the same size

The key to picture perfect keto sandwich cookies is to make the cookies the same size. Here’s how:
  • Use a cookie scoop – I used a 1.25 inch cookie scoop.
  • Use a piping bag – Add dough to a piping bag and squeeze out a 1.25 inch mound of cookie dough.
  • Roll into a ball – Pinch off some cookie dough and roll in between the palms of your hands to form about a 1 inch ball.

Storage information

The good news is these cookies stay soft and chewy days after you make them! So store your cookies either at room temperature or in the refrigerator for 7-10 days or until they start to taste old. You can freeze the keto oatmeal pies in a freezer safe container or bag for up to 1 month.

Frequently Asked Questions

Can I use real molasses?

Yes, you can use 1 tablespoon of blackstrap molasses in place of the molasses flavoring. Blackstrap molasses has sugar in it but it does contain minerals offering health benefits that may supersede the ill effects of sugar.

How to tell when cookies are done?

The keto oatmeal cookies are done baking when they start to turn golden brown around the edges (takes around 10 minutes). They will still be very soft to the touch, but will continue baking as they cool on the baking tray.

Help! My cookies fell apart. What did I do wrong?

Sounds like you were impatient and really wanted to eat that cookie now. The cookies will still be very soft when they first come out of the oven. Before you can handle them, let them cool on the baking sheet until you can slide a spatula underneath to transfer to a wire rack. The cookies will continue to set for several minutes (15-20 minutes). After that, you should be able to pick them up without them crumbling.

    These turned out way better than I hoped. The texture is soft and chewy and the cream filling is delicious. I’ve tried a few keto cookie recipes but this one actually tastes like the real thing. I'm going to try more of your recipes!

    Thanks for this awesome recipe Annie. I follow you on YouTube and have had success with a lot of your recipes. The only thing I substituted in this recipe was the butter in the filling, for palm shortening. The cookies are superb, and the filling came out delicious too.
    Anticipating your next creation. :)

    I am sure you get this question quite often. Do you know a way to make this without almond flour?

    1. Annie Lampella
      Annie Oct 10, 2023

      I haven't tried to make these without the almond flour. You could try to use lupin flour. The conversion is 1 cup almond flour is equal to 1/2 cup of lupin flour. For coconut flour, the conversion is 1 cup almond flour is equal to about 1/4 cup coconut flour.
