Equipment Needed
- Large mixing bowls
- Electric mixer or stand mixer
- Measuring cups and spoons
- Baking sheets
- Parchment paper
- Cookie scoop
- Cooling racks
- Offset spatula or piping bag
Step 1: Prepare Ingredients
Begin by bringing the butter and eggs to room temperature. Room-temperature ingredients blend more smoothly and create a more uniform cookie texture.
Measure all ingredients before mixing. This ensures accuracy and prevents mistakes during preparation.
Preheat the oven to 350°F (175°C). Line baking sheets with parchment paper.
Step 2: Cream the Butter and Sugars
Place softened butter in a large mixing bowl.
Add:
- Dark brown sugar
- Granulated sugar
Beat on medium speed for approximately 3–5 minutes until the mixture becomes light, creamy, and fluffy.
Proper creaming is essential because it incorporates air into the dough, creating cookies that are soft rather than dense.
Scrape down the sides of the bowl several times during mixing.
Step 3: Add Wet Ingredients
Add eggs one at a time.
Beat thoroughly after each addition.
Mix in:
- Vanilla extract
- Molasses
Continue beating until everything is completely incorporated.
The molasses contributes the signature flavor commonly associated with classic oatmeal cream pies. It also helps maintain moisture and softness.
Step 4: Mix Dry Ingredients
In a separate bowl combine:
- Flour
- Baking soda
- Baking powder
- Cinnamon
- Salt
If using optional spices, add them now.
Whisk thoroughly for at least 30 seconds to distribute the leavening agents evenly.
Step 5: Combine Wet and Dry Ingredients
Gradually add the dry mixture to the wet ingredients.
Mix on low speed until just combined.
Avoid overmixing because excess gluten development can produce tougher cookies.
Once the flour disappears, stop mixing.
Step 6: Add Oats
Add rolled oats gradually.
Mix until evenly distributed throughout the dough.
The dough will be thick and slightly sticky.
Allow the dough to rest for 10 minutes. This gives the oats time to absorb moisture and improves texture.
Step 7: Chill the Dough
Cover the bowl.
Refrigerate for 30 minutes.
Chilling helps:
- Prevent excessive spreading
- Improve flavor development
- Produce thicker cookies
- Create a chewier texture
For even richer flavor, dough may be refrigerated overnight.
Step 8: Portion the Cookies
Using a cookie scoop or spoon, portion dough into balls approximately 2 tablespoons each.
Place on prepared baking sheets.
Leave about 3 inches between cookies because they spread while baking.
Slightly flatten each dough ball with the palm of your hand.
Step 9: Bake the Cookies
Bake at 350°F (175°C) for 10–12 minutes.
The edges should appear set while the centers remain slightly soft.
Do not overbake.
The cookies continue cooking from residual heat after removal from the oven.
For especially soft oatmeal cream pies, remove them when they still look slightly underdone in the center.
Step 10: Cool Properly
Allow cookies to cool on baking sheets for 5 minutes.
Transfer to wire racks.
Cool completely before filling.
Warm cookies will melt the filling and create a messy sandwich.
Step 11: Prepare the Cream Filling
Place softened butter into a mixing bowl.
Beat for approximately 3 minutes until smooth and fluffy.
Gradually add powdered sugar.
Mix on low speed first to avoid a sugar cloud.
Increase speed and continue beating.
Add:
- Marshmallow creme
- Vanilla extract
- Heavy cream
- Salt
Beat for 4–5 minutes until light, fluffy, and silky.
The filling should be thick enough to hold its shape but soft enough to spread easily.
If too thick:
- Add a little cream
If too thin:
- Add more powdered sugar
Step 12: Pair the Cookies
Arrange cooled cookies according to size.
Match cookies with similar diameters to create attractive sandwiches.
Turn half of the cookies upside down.
These become the bottom halves.
Step 13: Fill the Cookies
Using a piping bag or spatula, place approximately 2–3 tablespoons filling onto each bottom cookie.
Spread nearly to the edges.
Place a second cookie on top.
Press gently until the filling reaches the edges.
Avoid pressing too hard.
The goal is a thick, generous cream layer.
Step 14: Rest the Finished Pies
After assembly, place oatmeal cream pies in a covered container.
Allow them to rest for at least 1 hour.
During this time:
- The filling settles
- The cookies soften slightly
- Flavors meld together
Many bakers believe oatmeal cream pies taste even better the next day.

Professional Tips for Extra Soft Cookies
