These oatmeal spice creme-filled cookies are much like those delicious oatmeal creme pies that we all love. A delicious layer of light creme is the perfect middle for this cookie sandwich!
In the bowl of an electric mixer, cream the butter and sugar until light, 3-5 minutes.
1 cup unsalted butter, room temperature, 1 cup brown sugar
Add eggs and mix until well incorporated, scraping the bowl to ensure even mixing.
2 eggs
Add flour, salt, baking powder, baking soda, cinnamon, nutmeg, allspice, and oats. Mix until no dry streaks remain. Scrape the bottom of the bowl for a final mix.
2 cups flour, 1 tsp salt, 1 tsp baking soda, ½ tsp baking powder, 1 tsp cinnamon, ½ tsp nutmeg, ¼ tsp allspice, 1 ½ cups old-fashioned rolled oats
On a parchment-lined baking sheet, make 1-ounce sized balls. Bake until the edges are set and the center springs back, 11-14 minutes.
Remove from the oven and allow to cool 5 minutes before removing from pan. Cool on a cooling rack.
For the creme filling
Beat all ingredients together until light, fluffy, and evenly incorporated. If too soft, add more powdered sugar, ¼ cup at a time; to soften, add additional milk.
½ cup unsalted butter, room temperature, 3 tbsp maple syrup, 1 tsp vanilla extract, ½ tsp cinnamon, 1 ½ cups powdered sugar
When the cookies are cooled, spread 1 teaspoon of filling on the bottom of one cookie. Top with another cookie. Continue until all cookies are used.
