How to Make Oatmeal Cream Pies
Step 1: Prepare Your Oven and Baking Sheets
Preheat your oven to 350°F (175°C). Line your baking sheets with parchment paper. This step ensures that your cookies don’t stick and helps them bake evenly.
Step 2: Mix Your Dry Ingredients
In a bowl, combine the oats, flour, cinnamon, baking soda, and salt. Whisk them together until they’re well mixed. This helps distribute the baking soda evenly so that all your cookies rise beautifully.
Step 3: Cream the Butters and Sugars
In another bowl, beat together the softened unsalted butter, brown sugar, and granulated sugar until light and fluffy. This process incorporates air into the mixture, giving your cookies that wonderful soft texture.
Step 4: Add Eggs and Flavorings
Next, mix in the eggs one at a time along with molasses and vanilla extract. Beat until everything is combined; this adds richness and depth of flavor to your cookie dough.
Step 5: Combine Wet and Dry Ingredients
Gradually add the dry ingredient mixture into the wet ingredients. Stir gently until just combined—overmixing can lead to tough cookies!
Step 6: Scoop and Bake
Using a cookie scoop or spoon, drop dollops of dough onto your prepared baking sheets. Bake for about 10 minutes or until they’re golden around the edges but still soft in the center. Let them cool completely on wire racks.
Step 7: Make the Frosting
While your cookies cool down, prepare the creamy filling by beating together softened butter with vegan marshmallows creme until smooth. Gradually add sifted powdered sugar, vanilla extract, and salt while mixing until it reaches a fluffy consistency.
Step 8: Assemble Your Oatmeal Cream Pies
Once cookies are cool, spread frosting onto one cookie half before topping it with another cookie half. Press gently together so they hold their shape.
And there you have it—your very own batch of delightful Oatmeal Cream Pies! Enjoy them fresh or share with friends; they’re bound to be a hit!
Pro Tips for Making Oatmeal Cream Pies
Creating the perfect Oatmeal Cream Pies can be a delightful experience, and with these handy tips, you’ll ensure your pies are soft, chewy, and irresistibly delicious!
- Use room temperature ingredients: Keeping your butter and eggs at room temperature helps them incorporate more easily into the dough, leading to a smoother texture in your cookies.
- Don’t overmix the dough: Mixing just until the ingredients are combined prevents the cookies from becoming tough. A light hand is key to maintaining their soft and chewy consistency.
- Chill the dough if needed: If your dough feels too sticky or soft, refrigerate it for about 30 minutes. This will make it easier to scoop and shape, resulting in perfect cookie rounds.
- Watch your baking time closely: Every oven is different! Check your cookies a minute or two before the recommended time to avoid over-baking. They should look set but still soft when you take them out.
- Experiment with add-ins: Feel free to get creative by adding chocolate chips or raisins for an extra touch of sweetness. Just remember to adjust the baking time slightly if you add more moisture.
How to Serve Oatmeal Cream Pies

- Chocolate drizzle: Drizzling melted dairy-free chocolate over the top creates a beautiful finish and enhances the flavor complexity.
Side Dishes
- Fresh fruit salad: A vibrant mix of seasonal fruits adds a refreshing contrast to the sweetness of the cookies. The natural juices help cleanse the palate between bites.
- Vegan ice cream: Pairing these pies with a scoop of vegan ice cream creates an indulgent dessert experience that’s perfect for warm days or special occasions.
- Nut butter dip: Serve alongside a small bowl of almond or peanut butter for dipping, offering both protein and richness that complements the sweetness of the pies beautifully.
