- 1 7.5oz jar of marshmallow fluff 1/2 stick butter

- Add cake mix, eggs, oil, vanilla and sprinkles to a large bowl and stir until fully incorporated. Using a small cookie scoop, scoop even balls of the cookie dough onto a parchment lined baking sheet.
- Leave 2 inches between each ball of dough so it has room to expand
- Bake in a 375 degree oven for 10-12 mins or until the edges begin to brown.
- All to cool.
- Make the marshmallow icing by beating fluff and butter until smooth.
- Add in the confectioners sugar a little at time beating until smooth.
- Icing should not be super stiff but fall into a ribbon pattern.
- Using the same scooper from the cookies, add one scoop of icing to the cooled cookies. Roll in the sprinkles.
- Serve at room temperature or serve cold.
These sandwiches will mimic an ice cream sandwich if chilled or lightly frozen, without melting. If the icing doesn’t fall in a ribbon pattern, add a teaspoon of water to loosen it up a bit.
Avoid a wax coated sprinkle for this dessert. It will make for a better tasting experience!
