These flavorful browned butter oatmeal cookie pies are crispy on the outsides, gooey on the inside oatmeal cookies with marshmallow frosting sandwiched in between.
First, brown your butter. Place the unsalted butter in a medium-sized saucepan over medium heat. Allow it to melt and then boil. When your butter is done once the boiling bubbles stop making cracking and popping noises.
Pour the hot butter over the brown sugar in a small mixing bowl. Stir and allow the hot butter to start to melt the sugar and cool down.
Preheat your oven to 375 degrees
Pour the butter and sugar mixture into the bowl of a standing mixer, turn the mixer on medium speed and whip until the butter is no longer warm.
Add the eggs and vanilla, stir until combined.
Now add the flour, oats, baking soda, cinnamon and salt. Mix on low until just combined.
Scoop the cookies using a standard size cookie scoop onto light metal cookie sheet lined with parchment paper.
Bake for 9-10 minutes. Remove and allow the cookies to sit on the pan for 5-10 minutes while the cool and set.
Remove the cookies and allow them to fully cool before frosting.
Frosting
Combine marshmallow creme, powdered sugar, vanilla, and cream in a medium-sized bowl with a hand mixer. Mix until smooth.
Scoop a spoonful of frosting on the backside of one cookie and top it with another cookie to make a sandwich. This recipe should make 11-12 sandwiches.
