Keto Oatmeal Cream Pies

I love a good oatmeal cream pie, but traditional oatmeal cookies are difficult to fit into a low-carb lifestyle. Rolled oats, flour, and plenty of sugar are what give the original cookies their familiar texture and sweetness.

These keto oatmeal cream pies take a different approach.

Instead of rolled oats, the cookies use almond flour and oat fiber. The oat fiber gives them that slightly rough, chewy texture that makes an oatmeal cookie feel like an oatmeal cookie, while cinnamon and vanilla bring in the warm flavor I associate with the classic treat.

Then there is the filling.

A simple whipped cream cheese filling gets sandwiched between two soft cookies, creating a homemade keto version that’s creamy, chewy, and surprisingly satisfying.

The cookies don’t require a long chilling time either, so once the dough is mixed, you can roll it out, cut your rounds, and get them into the oven.

Why You’ll Love These Keto Oatmeal Cream Pies

They have an oatmeal-like texture. Oat fiber adds a slightly textured bite that you don’t get from almond flour alone.

They’re soft and chewy. The cookies are baked just until the edges set, allowing the centers to stay tender.

The filling is light and creamy. Cream cheese, butter, powdered sweetener, and vanilla make a smooth filling that works beautifully with the cinnamon cookies.

No traditional rolled oats are needed. This recipe uses oat fiber instead of oats.

The dough is easy to work with. You can roll and cut it without a lengthy refrigeration step.

They’re great for making ahead. The cookies can be baked in advance and assembled when you’re ready.

A Quick Note About Oat Fiber

Oat fiber is important in this recipe, but oat fiber and oat flour are not the same thing.

Oat flour is made by grinding oats and contains the carbohydrates naturally found in the oat grain. Oat fiber is made from the fiber portion of the oat and is commonly used in low-carb baking to add bulk and texture.

For this recipe, look specifically for a package labeled oat fiber, not oat flour, oat bran, or ground oats.

Because nutrition information varies between brands, check the label on the oat fiber you purchase when calculating the nutrition for your particular batch.

Ingredients

For the Cookies

• 1/2 cup unsalted butter, softened
• 1/2 cup keto brown sugar substitute
• 1 large egg
• 1 teaspoon vanilla extract
• 1 1/4 cups finely ground blanched almond flour
• 1/3 cup oat fiber
• 1 teaspoon ground cinnamon
• 1/2 teaspoon baking soda
• 1/4 teaspoon fine sea salt

For the Cream Filling

• 4 ounces full-fat cream cheese, softened
• 3 tablespoons unsalted butter, softened
• 1/2 cup powdered keto sweetener
• 1 teaspoon vanilla extract

Ingredient Notes

Almond Flour

Use finely ground blanched almond flour rather than almond meal. Fine almond flour gives the cookies a more even texture and keeps them from becoming gritty.

Oat Fiber

This is the ingredient that provides much of the oatmeal-like texture.

Different brands can vary in how absorbent they are, so if your dough feels particularly dry, don’t automatically add a large amount of liquid. A teaspoon of water at a time is enough to adjust it.

Keto Brown Sugar Substitute

A brown-sugar-style keto sweetener gives these cookies a deeper flavor than plain granulated sweetener.

Allulose-based and erythritol-based blends can behave differently during baking, so use the product according to its intended substitution ratio.

Cream Cheese

Full-fat cream cheese gives the filling the richest texture. Let it soften before mixing so the filling becomes completely smooth.

How to Make Keto Oatmeal Cream Pies

Step 1: Prepare the Dough

Preheat your oven to 325°F (165°C).

Line a large baking sheet with parchment paper.

Add the softened butter and keto brown sugar substitute to a mixing bowl. Beat with a hand mixer or stand mixer until creamy.

Add the egg and vanilla and mix until combined.

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

Add the dry ingredients to the butter mixture and mix just until a soft dough forms.

Don’t continue mixing once everything is incorporated.

Step 2: Roll the Dough

Place the dough between two sheets of parchment paper.

Roll it to approximately 1/4 inch thick.

Try to keep the thickness consistent across the entire sheet. This helps the cookies bake evenly and makes it easier to match cookies together later.

Step 3: Cut the Cookies

Remove the top piece of parchment.

Use a round cookie cutter or a clean drinking glass to cut the dough into rounds.

You want approximately 16 cookies for 8 cream pies.

Transfer the rounds carefully to the prepared baking sheet.

Gather the leftover dough, gently press it together, and roll it again to cut the remaining cookies.

Step 4: Bake

Bake for 9 to 11 minutes.

The edges should be set while the centers still look slightly soft.

Don’t wait for the entire cookie to become firm in the oven. They continue to firm as they cool, and overbaking can make them dry.

Step 5: Cool

Leave the cookies on the baking sheet for several minutes.

Then transfer them to a wire rack and allow them to cool completely.

This is especially important before adding the filling. Warm cookies will soften the cream filling and can cause it to slide out.

Step 6: Make the Filling

Add the softened cream cheese and butter to a mixing bowl.

Beat until completely smooth.

Add the powdered keto sweetener and vanilla extract.

Beat again until the filling is light and fluffy.

If the filling seems too soft, refrigerate it for about 15 minutes before assembling the cookies.

Step 7: Assemble

Turn half of the cooled cookies flat-side up.

Pipe or spread an even layer of filling onto each cookie.

Place a second cookie on top and gently press until the filling reaches toward the edges.

Repeat with the remaining cookies.

Tips for the Best Cookies

Don’t Overbake Them

This is probably the most important tip.

The centers should still look a little soft when you remove the cookies from the oven. They will continue cooking from the residual heat and become firmer as they cool.

Roll Them Evenly

If some cookies are 1/8 inch thick and others are 1/4 inch thick, they won’t bake at the same rate.

Keeping the dough around 1/4 inch thick gives you soft cookies that are sturdy enough to sandwich.

Let Them Cool Completely

I know it’s tempting to fill them as soon as they’re cool enough to handle, but wait.

The cream filling needs to sit between completely cooled cookies or it can become too soft.

Use Finely Grated Ingredients

Fine almond flour and finely processed oat fiber blend more evenly into the dough, giving the finished cookies a better texture.

Chill the Filling if Needed

If your kitchen is warm, the filling may be softer than you’d like.

A short 15-minute chill makes it easier to pipe and gives the finished cream pies cleaner edges.

If the Dough Is Too Crumbly

Oat fiber absorbs moisture, and some brands are more absorbent than others.

If your dough cracks badly when you try to roll it, add 1 teaspoon of water or softened butter at a time and gently mix until the dough becomes workable.

Don’t add a large amount of liquid at once.

If the Cookies Spread

The butter may have been too warm.

Softened butter should be easy to mix but shouldn’t be melted or oily.

Also check that you measured the almond flour and oat fiber accurately.

If the dough feels unusually soft, place it in the refrigerator for 10 to 15 minutes before rolling.

If the Cookies Are Too Hard

The most common reason is overbaking.

Take them out when the edges are set and the centers still look slightly soft.

They will firm considerably as they cool.

If the Filling Is Too Soft

Make sure both the cream cheese and butter aren’t overly warm.

After mixing, refrigerate the filling for about 15 minutes before piping.

This is especially helpful during warmer weather.

Can I Make These Without a Cookie Cutter?

Absolutely.

A clean drinking glass works well as a makeshift round cutter.

Just press it straight down into the rolled dough and lift it straight back up.

Avoid twisting too aggressively because it can distort the edges of the cookies.

What to Serve With Keto Oatmeal Cream Pies

These are especially good with something unsweetened alongside them.

Coffee

The cinnamon and vanilla pair beautifully with hot coffee.

Unsweetened Almond Milk

A cold glass of almond milk makes these feel especially close to the classic snack.

Fresh Berries

Raspberries or strawberries add a fresh, slightly tart contrast to the sweet filling.

How to Store Them

Store assembled cream pies in an airtight container in the refrigerator for up to 1 week.

The filling will become firmer when chilled. If you prefer a softer texture, let a cream pie sit at room temperature for a few minutes before eating.

For longer storage, the unfilled cookies can be frozen in a freezer-safe container for up to 3 months.

Place parchment between layers to keep the cookies from sticking together.

Thaw the cookies completely before filling.
