substitutions and additions
Vegetable Shortening: it may seem strange to use both butter and vegetable shortening in the recipe, but it is best to get the lighter, fluffier texture while also having the richness that comes from the butter.
Cocoa: you can use most types of cocoa but avoid Dutch-pressed because it has less acidity, and this can have a negative effect on the leavening of the cookies
Oats: quick cook oatmeal is the best for this because old fashioned oats tend to be chewier. They also cook quicker and this alters the texture. But if you want, you can pulse all of the oats in the food processor and the recipe still works just as well.
How to make this oatmeal cream pies recipe
OATMEAL COOKIES
STEP ONE: In a large mixing bowl, beat the shortening and butter on medium speed for 3 minutes.
STEP TWO: Reduce the speed to low and add both sugars then beat until combined.
STEP THREE: Add the eggs, molasses, and vanilla then beat until combined.
STEP FOUR: Combine the dry ingredients in a medium bowl then use a whisk to stir away any lumps of flour.
STEP FIVE: Add the dry ingredients to the mixing bowl. Start on a low speed and gradually move up to a medium speed to mix everything.
STEP SIX: Refrigerate the dough for at least 20 minutes. Preheat the oven to 350 degrees and line a cookie sheet with a baking mat or spray with a cooking spray.
STEP SEVEN: Using a 1 tablespoon cookie scoop, place scoops of dough on the cookie sheet 2 inches apart. Use the flat bottom of a glass to press them down until 1/2 inch thick. You may want to spray the bottom of the glass with the cooking spray before doing this to stop them from sticking.
STEP EIGHT: Bake the cookies for 10 minutes, remove from the pan and cool completely.
CREAM FILLING
STEP ONE: In a medium mixing bowl, beat the butter and vegetable shortening on medium for 5 minutes.
STEP TWO: Add the marshmallow cream, powdered sugar, and salt. Start on low speed then increase to medium until combined.
STEP THREE: Spread 2 to 3 teaspoons of filling on the bottom side of one cookie then place a second cookie on top with the bottom side against the filling.
storage
ON THE COUNTER: You can store the cookies in an airtight box on the counter for up to 3 days. Or if you want to keep them fresh for longer, pop them in a sandwich box in the fridge and they should last for a week. It is best to let them come back to room temperature before eating (if you can wait) so lift them out about an hour before eating.
IN THE FRIDGE: Before you cook the dough, you can leave it in the fridge overnight if you want to prepare it ahead of time without any issues.
IN THE FREEZER: You can freeze oatmeal cream pies by wrapping them tightly and popping them in the freezer. Make sure you use them within three months while they are still at their best.
Enjoy these homemade cookies any time you want with this easy copycat recipe. Tuck into the best oatmeal pie with a creamy filling or even try swapping the flavor of the filling for a new experience. However you serve it, these will become a firm family favorite!
