These Oatmeal Pumpkin Creme Pies are tasty any time of year, but definitely hit the spot during those cooler fall months. Soft, chewy, and so much sweet pumpkin and cinnamon flavors.
Like a batch of pumpkin oatmeal cookies and oatmeal creme pies in one, these sandwich cookies are ready for your next fall baking day. We add pumpkin to the cream cheese frosting, so it’s a little thinner than a batch of regular cream cheese frosting. I like to use a little flour in the frosting to help thicken it up, and make sure you heat-treat it before using. (See below for details.)
You also add lots of delicious spices to the frosting including cinnamon, nutmeg, cloves, and ginger. You could absolutely replace all of these with store-bought or homemade pumpkin pie spice or just replace the nutmeg, cloves, and ginger with it (and leave the cinnamon in the recipe). Either way works.
For a totally different flavor, especially around the winter holidays, try these spiced eggnog oatmeal cream pies too!
Since pumpkin can thin out the frosting, I recommend blotting some moisture out of it before using. This is a tried-and-true trick I use when making pumpkin rice krispie treats and pumpkin snickerdoodles, too. Excess moisture is great for pumpkin muffins and pumpkin cake, but not really a frosting or cookie recipe.
How to Heat Treat Flour
Option 1 – Microwave
- You can heat treat your entire bag of flour or just treat the amount you need in a single recipe. If you’re heating just enough for the recipe, add an extra 1/2 – 1 cup to be sure you have enough.
- Place the flour in a microwave-safe bowl and heat on high for 30 seconds at a time, stopping and stirring after each. Stir well to make sure none of the flour burns. Use an instant-read thermometer to test the flour in several places to make sure it has reached 165°F (74°C). If you get a lower reading in one area, stir and heat for an additional 30 seconds until it’s all ready.
- Measure the amount of flour you need and use in the recipe, then let it cool completely.
Option 2 – Oven
- Preheat oven to 300°F (149°C). Spread more flour than the recipe calls for on an un-greased rimmed baking pan, such as a 9×13-inch baking pan or 9-inch square baking pan. Then follow a process similar to the microwave method by stirring and checking the temperature at 2 minute intervals. Be sure to check multiple spots of the flour to make sure it has all reached 165°F (74°C).
- If some flour sticks to the bottom or sides of the pan, don’t worry, just leave it there. You used more flour than needed in the recipe anyway. Don’t scrape it off because it will add small clumps to your batter/dough.
- If your flour is really clumpy, your oven might be too hot. Break it up with your fingers or pour all the flour into a bowl and whisk it. Discard any chunks if necessary.
- Measure the amount of flour you need and use in the recipe, then let it cool completely.

Ingredients
Oatmeal Sandwich Cookies
- 1/2 cup (8 Tbsp; 113g) unsalted butter, softened to room temperature
- 3/4 cup packed dark brown sugar
- 1/2 cup granulated sugar
- 1 large egg, at room temperature
- 2 teaspoons pure vanilla extract
- 1/2 teaspoon baking soda
- 1/2 teaspoon ground cinnamon
- 1 and 2/3 cups old-fashioned rolled oats
- 1 cup all-purpose flour (spooned & leveled)
Pumpkin Cream Cheese Frosting
- 4 ounces (113g) full-fat brick cream cheese, softened to room temperature
- 2 Tablespoons (28g) unsalted butter, softened to room temperature
- 1/4 cup canned pumpkin puree (see note)
- 1 teaspoon ground cinnamon
- 1/4 teaspoon each: ground ginger, ground cloves, and ground nutmeg (or 3/4 teaspoon pumpkin pie spice)
- 2 – 2 and 1/2 cups confectioners’ sugar, sifted
- 1/4 cup heat-treated all-purpose flour* (as needed to thicken)
- salt, to taste
Instructions
- Using a handheld or stand mixer fitted with a paddle attachment, beat the softened butter and sugars together on medium-high speed until smooth. Add the egg and vanilla and mix well. Scrape down the sides and bottom of the bowl as needed. In a separate bowl, whisk the baking soda, cinnamon, oats, and flour. Add the dry ingredients to the wet ingredients, then mix together until just combined. Do not overmix.
- Chill the dough for at least one hour (and up to 1 day) in the refrigerator. Cookies will be very flat if the dough is not cold, so don’t skip this step.
- Preheat oven to 325°F (163°C). Line a cookie sheet with parchment paper or a silicone baking mat. Roll 2 teaspoons of dough into a ball and place onto prepared sheet. Bake for 9 minutes and let cool on cookie sheet for a minute or two before transferring to a wire rack.
- While the cookies are cooling, prepare the pumpkin frosting. Using a handheld or stand mixer fitted with a paddle or whisk attachment, beat the cream cheese, butter, pumpkin, and spices on medium speed until creamy. Add 2 – 2 and 1/2 cups of sifted confectioners sugar depending how sweet you’d like it. If frosting is much too thin, add in the heat-treated flour to thicken it. Add salt to cut the sweetness, if you prefer.
- Spread a generous amount of frosting on the underside of a cooled cookie and sandwich another cookie on top. Cookies stay fresh for up to 5 days in an airtight container in the refrigerator.
Notes
- Make Ahead & Freezing Instructions: You can prepare the cookies and filling 2 days in advance—keep the cookies covered tightly at room temperature and the filling covered tightly in the refrigerator. Cookies freeze well, up to 2-3 months. Thaw overnight in the refrigerator before enjoying.

- Pumpkin: I find that blotting some of the moisture out of the pumpkin before using in the frosting will help the frosting stay a little thicker. There is SO much moisture in pumpkin puree and it won’t do the frosting many favors! Measure 1/4 cup of pumpkin puree and then blot it between two paper towels to absorb some moisture. Then use in the recipe as instructed.
- Spices in Frosting: You can replace the cinnamon, ginger, cloves, and nutmeg with store-bought or homemade pumpkin pie spice. You could also replace just the nutmeg, ginger, and cloves with pumpkin pie spice and leave the cinnamon in the recipe.
