- 1 3/4 cup All-purpose flour
- 1 tsp Baking soda
- 1 tsp Salt
- 1 tsp Ground cinnamon
- 1/2 tsp Pumpkin pie spice
- 3 cups Old fashioned oats
- 1 cup Unsalted butter (room temperature)
- 1 cup Light brown sugar (packed)
- 1/2 cup White granulated sugar
- 1 tsp Pure vanilla extract
- 1/2 TBSP Unsulfured molasses (not blackstrap)
- 2 Large eggs (room temperature)
Apple Pie Filling
- 3 Gala apples (peeled)
- 2 TBSP Unsalted butter
- 1/2 cup Light brown sugar (packed)
- 1 tsp Ground cinnamon
- 1/4 tsp Ground nutmeg
- 2 TBSP Water
- 1 tsp Cornstarch
Marshmallow Creme Frosting
- 1 cup Unsalted butter (room temperature)
- 7 oz Marshmallow creme
- 1 cup Powdered sugar (sifted)
- 1 tsp Pure vanilla extract
- Pinch of salt
Instructions
- Mix dry ingredients: In a medium bowl, sift the flour and add the baking soda, salt, cinnamon, pumpkin pie spice, and oats. Stir to combine and set aside.
- Beat butter and sugars: Using a mixer in a large bowl, beat the unsalted butter, light brown sugar, and white granulated sugar on high speed for 2 minutes until pale and fluffy.
- Add wet ingredients: Mix in vanilla extract, molasses, and eggs on medium speed until fully incorporated.
- Combine dry and wet: Add the flour and oat mixture to the wet ingredients and mix on low speed until just combined to avoid overmixing.
- Chill dough: Cover the bowl with dough and refrigerate for 45 minutes to allow oats to absorb moisture and dough to firm up.
- Preheat oven and prepare pans: Heat oven to 350℉ (175℃) and line two cookie sheets with parchment paper.
- Scoop dough: Using a 1 1/2 tablespoon cookie scoop, portion 12 dough balls per cookie sheet, spacing evenly.
- Bake cookies: Bake one tray at a time for 9-11 minutes or until edges are lightly golden.
- Cool cookies: Let cookies cool on the hot sheet pan for 5 minutes, then transfer to a wire rack to cool completely before decorating.
- Prepare apple filling: While dough chills, peel and dice apples into small pieces.
- Cook filling: In a large sauté pan over medium heat, melt butter, then add diced apples, brown sugar, cinnamon, nutmeg, water, and cornstarch. Stir with a rubber spatula.
- Simmer filling: Cook for 5–10 minutes until apples are soft and mixture thickens.
- Cool filling: Transfer to a bowl and allow to cool to room temperature.
- Sift powdered sugar: In a medium bowl, sift powdered sugar to remove lumps.
- Make frosting base: Beat room temperature butter on high speed for 2 minutes until fluffy. Add marshmallow creme and continue mixing on high speed for 1 minute. Scrape down sides.
- Combine frosting: Add sifted powdered sugar, vanilla extract, and a pinch of salt. Mix on low speed until incorporated, then beat on high speed until smooth and creamy.
- Assemble cream pies: Pair cookies by size. Pipe a border of frosting along the edge of one cookie, leaving the center open, fill the middle with apple pie filling, then top with the matched cookie.
- Set frosting: Place assembled cream pies in the freezer for 15 minutes to set frosting.
- Store: Keep the cream pies refrigerated to maintain firmness; chilling prevents frosting from squishing out when bitten.
Notes
- Make sure the butter and eggs are at room temperature for best mixing results.
- Chilling the dough is crucial for texture and to prevent spreading while baking.
- You can substitute Gala apples with a tart variety like Granny Smith for a tarter filling.
- Use parchment paper or silicone mats to prevent sticking and ensure even baking.
- For easier piping, fit your piping bag with a large French star tip to create decorative frosting borders.
- Store finished cream pies in the refrigerator and consume within 3-4 days for freshness.
