1-Getting Started: Before you dive in, gather all your ingredients and tools to make the process smooth. This recipe yields about 15 cookie sandwiches and takes around 1 hour and 30 minutes total, so it’s a fun project for any day. Preheat your oven to 375°F and line your baking sheets with parchment paper to avoid any sticky messes.

2-First Step: In a large bowl, beat 1 and 1/4 cups of unsalted butter with 1 cup packed dark brown sugar and 1/2 cup granulated sugar until the mixture is light and creamy. This step ensures the base of your oatmeal creme pies is fluffy and well-mixed, which is key for that soft texture.

3-Second Step: Add 1 large egg, 2 teaspoons pure vanilla extract, and 1 Tablespoon unsulphured or dark molasses to the bowl, then beat until everything combines smoothly. For those adapting for dietary needs, you could swap the egg here for a flax egg if going vegan, keeping your oatmeal creme pies inclusive.

4-Third Step: In a separate bowl, whisk together 1 and 2/3 cups all-purpose flour, 1 teaspoon baking soda, 1/2 teaspoon salt, 3/4 teaspoon ground cinnamon, 1/4 teaspoon ground cloves, and 3 cups quick oats. Slowly add this dry mixture to the wet ingredients on low speed with your mixer, blending until just combined to form the dough for your oatmeal creme pies.

5-Fourth Step: Scoop out 2 tablespoons of dough per cookie and arrange 6 per baking sheet, giving them space to spread. Bake for 10 to 13 minutes until the edges turn lightly golden, then let them cool completely on the sheets. This timing helps keep the centers soft, perfect for classic oatmeal creme pie, and you can adjust for higher altitudes by adding a bit more flour if needed.

6-Fifth Step: While the cookies cool, make the filling by beating 3/4 cup unsalted butter until creamy, then add 3 cups confectioners sugar, 3 Tablespoons heavy cream, and 1 and 1/2 teaspoons pure vanilla extract. Beat until fluffy and add salt to taste; for a lower-calorie version, try reducing the sugar or using a substitute here to customize your oatmeal creme pies.

7-Final Step: Spread the filling on the flat side of half the cooled cookies and sandwich them with the remaining cookies. Serve right away or store for later, and feel free to experiment with flavors like adding nuts for a twist. This method ensures your oatmeal creme pies are as delicious as they are adaptable, making them a hit for all kinds of eaters.
