They are a lovely choice for afternoon treats, lunchbox desserts, bake sales, or sharing with family and friends.

Homemade Oatmeal Cream Pies Ingredients

This recipe has two main components: the oatmeal cookies and the cream filling. Preparing both separately makes assembly easier once the cookies have cooled completely.

Oatmeal Cookie Ingredients

• Unsalted butter: One cup of softened butter provides richness and helps create the cookie texture.
• Brown sugar: One cup, packed, adds moisture and a deep caramel-like sweetness.
• Granulated sugar: Half a cup balances the brown sugar and contributes to the cookie structure.
• Molasses: One tablespoon adds a distinctive warm flavor associated with classic oatmeal cookies. Honey is listed as an alternative in the original recipe.
• Vanilla extract: Two teaspoons provide a familiar vanilla aroma.
• Eggs: Two large eggs bind the ingredients and contribute to the cookie structure.
• All-purpose flour: Two cups provide the structure needed for cookies that hold their shape.
• Cinnamon: Half a teaspoon adds gentle warmth.
• Baking soda: One teaspoon helps the cookies rise and spread.
• Salt: A quarter teaspoon balances the sweetness.
• Quick oats: Three cups give the cookies their characteristic oatmeal texture. Rolled oats are also an option according to the original recipe.

Cream Filling Ingredients

• Unsalted butter: Three-quarters of a cup forms the rich base of the frosting.
• Cream cheese: Two ounces of full-fat, brick-style cream cheese add creaminess and a slight tang.
• Powdered sugar: Three to four cups provide sweetness and help the filling reach the desired consistency.
• Vanilla extract: One teaspoon enhances the flavor.
• Salt: A quarter teaspoon balances the sweetness.
• Cream: One tablespoon, if needed, helps loosen the frosting if it becomes too thick.

Helpful Tips for the Best Oatmeal Cream Pies

Measure the flour carefully. Too much flour can make the cookies dry. The original recipe recommends whisking the flour first, then spooning it into a dry measuring cup and leveling the top, or measuring by weight.

Use softened butter. Softened butter is easier to beat with the sugars and helps create a fluffy mixture. The cream cheese for the filling should also be softened enough to blend smoothly.

Start mixing the dry ingredients slowly. Stir the flour mixture briefly by hand before turning on the mixer at low speed. This helps prevent flour from scattering.

Use a cookie scoop for consistent sizes. Portion the dough into balls of about 1 to 1.5 tablespoons. Similar-sized cookies are easier to pair when assembling the sandwiches.

Bake one sheet at a time. The original instructions recommend baking one sheet in the middle of the preheated oven. Bake for approximately 9–11 minutes, until the tops look set.

Let the cookies cool completely. Allow them to cool on the baking sheet for at least 10 minutes before transferring them to a wire rack. They need to cool fully before you add the frosting, or the filling may soften too much.

Adjust the frosting gradually. Start with 3 cups of powdered sugar and add more in increments of about half a cup until you reach your preferred sweetness and consistency. Add the tablespoon of cream if the frosting is too thick.

How to Make Homemade Oatmeal Cream Pies

Step 1: Prepare the Oven and Baking Sheets

Preheat the oven to 350°F (180°C, or 170°C fan-forced). Line cookie sheets with silicone baking mats or baking paper.

Step 2: Beat the Butter and Sugars

In a large bowl, beat 1 cup softened unsalted butter with 1 cup packed brown sugar and 1/2 cup granulated sugar until fluffy.

This step helps combine the butter and sugars evenly before the remaining ingredients are added.

Step 3: Add the Wet Ingredients

Mix in 1 tablespoon molasses, 2 teaspoons vanilla extract, and 2 large eggs. Beat until the mixture looks creamy.

Step 4: Add the Dry Ingredients and Oats

Turn off the mixer and add 2 cups all-purpose flour, 1/2 teaspoon cinnamon, 1 teaspoon baking soda, and 1/4 teaspoon salt.

Stir a few times by hand, then mix on low speed until incorporated. Stir in the 3 cups of quick oats.

Step 5: Shape and Bake the Cookies

Form the dough into balls measuring approximately 1 to 1.5 tablespoons each. Place them about 2 inches apart on the prepared baking sheets.

Bake one sheet at a time in the middle of the oven for 9–11 minutes, or until the tops look set.

Let the cookies cool on the baking sheet for at least 10 minutes before moving them to a wire rack to finish cooling.

Step 6: Make the Cream Filling

In a large bowl, beat 3/4 cup softened unsalted butter until fluffy.

Cut 2 ounces of full-fat, brick-style cream cheese into three or four pieces and beat them into the butter.

Add 1 1/2 cups powdered sugar, 1 teaspoon vanilla extract, and 1/4 teaspoon salt. Begin mixing on low speed, then gradually increase to medium until incorporated.

Continue adding powdered sugar about 1/2 cup at a time until the filling reaches your desired sweetness and consistency, using 3–4 cups in total. If the frosting is too thick, beat in 1 tablespoon cream.

Step 7: Assemble the Cookie Sandwiches

Once the cookies are completely cool, spread approximately 1 to 1.5 tablespoons of frosting onto the flat bottom of one cookie.

Place a second cookie on top, with its bottom facing down, to create a sandwich.

Repeat with the remaining cookies and filling. The recipe typically yields approximately 16 sandwich cookies, depending on the size of the cookies.

Variations and Substitutions

Use Honey Instead of Molasses

The original recipe lists honey as an alternative to the tablespoon of molasses. Honey will give the cookies a different flavor, so the finished result may not have exactly the same traditional molasses taste.

Choose Quick Oats or Rolled Oats

Quick oats are the preferred option in the original recipe, but rolled oats can also work. They may create a slightly different texture in the finished cookies.

Adjust the Cream Filling

Use between 3 and 4 cups of powdered sugar according to your preferred sweetness and frosting consistency. The recipe also allows the cream cheese to be replaced with more butter, although this will change the filling’s flavor and texture.

Make a Smaller Batch

The original recipe notes that it can easily be divided in half if you want fewer cookie sandwiches.

Serving Suggestions

Homemade Oatmeal Cream Pies are delicious served as an afternoon treat, packed for a picnic, or arranged on a dessert platter for a family gathering.

• With a dessert platter: Arrange the cookie sandwiches alongside other homemade cookies and small treats.
• For lunchboxes: Pack a cookie sandwich as an occasional sweet treat.
• For bake sales: Their individual portions make them convenient to display and serve.
• For homemade gifts: Place fully cooled and assembled cookies in a suitable container for sharing.

For the neatest presentation, allow the frosting to settle between the cookies before arranging the sandwiches on a serving plate.

Frequently Asked Questions
