Spoiler alert – I succeeded. Try these!!
- 1 cup butter, softened to room temperature
- 1 cup sugar
- 1 cup dark brown sugar
- 2 eggs
- 2 t vanilla
- 2 cups flour
- 1 ½ t baking soda
- ½ t baking powder
- ½ t salt
- 3 cups old fashioned oats, uncooked
- ½ cup butter, softened to room temperature
- ¼ cup shortening
- 1 ½ cups powdered sugar
- 1 t vanilla
- 1 jar (7oz) marshmallow cream
DirectionsOverall, these are pretty easy. We’ll make the cookies first. Start by putting the butter, sugar and brown sugar into a large bowl and beat with your mixer until well combined and fairly smooth – probably a couple minutes.
Next, add in the eggs and vanilla and beat again until everything is well combined.
In a separate, small bowl whisk together the flour, baking soda, baking powder and salt. Once they are all combined, add that to the butter mixture and mix well. Finally, add in the oats and stir with a wooden spoon until well combined.
When you’re ready to bake, heat the oven to 350 and place the cookies on cookie sheets lined with parchment paper. These will spread a bit, so you’re limited to 6 per sheet. One thing to be careful about – since we’re making sandwich cookies you should make sure that each cookie is about the same size, preferably about the size of a walnut. Press down on each ball with the palm of your hand – just a little bit – to flatten it slightly.
Bake for about 9-10 minutes, until the cookies start to get golden brown on the edges and bottoms. Take them out of the oven, let them sit on the cookie sheets for a couple minutes and then transfer them to a wire rack to cool completely.
On to the filling!
Make sure the cookies are completely cool before you put the filling on, otherwise the heat will melt the filling and you’ll have a mess on your hands.
To make the filling, put the butter and shortening into a bowl and beat together until they’re smooth – just a couple minutes. Next add in the powdered sugar and beat until just combined. Finally, add in the vanilla and the marshmallow and beat that until everything is well combined.
Pair off your cookies so that each pair is the same size. Place a dollop of filling on one half and cover with the other half.
This’ll make 30 or so cookies, depending on how large you make them (well, in theory it could make ONE cookie if you made it really big – but you know what I mean).
