Can I Make Different Flavored Cookies?

Of course! One of the best things about this is that the base is a cake mix so you can easily swap out flavors. I love the basic vanilla when using sprinkles, but this would be excellent with different flavors. Below are a few I think would pair especially well with the marshmallow cream icing.

Strawberry
Lemon
Spice
Chocolate
Carrot

What Type of Sprinkles Should I Use?

In this recipe, you could reach for any sprinkle you want. The softer non-wax coated sprinkles work best with this as they melt in your mouth rather than being crunchier. Whatever you use will be delicious, and the fun part of this is that you can decorate them with different themes for different reasons. Below are a few of my favorite sprinkle blends.

You can also use sanding sugars in place of the sprinkles if you prefer. They can be a bit messier but they look great with the cookies for special holidays!

What Should I Fill My Cookies With?

Below, you will find a recipe for marshmallow frosting. This is a simple homemade filling that is delicious and pairs wonderfully with these cookies. If you prefer to use something different, feel free to grab any of your favorite prepared icings in the grocery store. You can even make your own traditional buttercream or cream cheese icing if you prefer.

Do These Need to be Refrigerated?

While you don't have to refrigerate these cookies for food safety reasons, it is a good idea to refrigerate them after filling. The frosting itself is fine at room temperature, but refrigerating or freezing these once filled gives a wonderful texture that is similar to ice cream. That makes for a better snack and one that is even better.

If you decide to keep these at room temperature, just make sure they are stored in an airtight container. They are good for 3-4 days on the counter or up to one week in the refrigerator.

How Many Cookies Does This Batch Make?

The number of cookies depends upon the size of the cookie scoop you use to make your dough balls. Since each cookie is actually two cookies combined into a sandwich, it will result in anywhere from 12 to 18 cookie sandwiches per batch. You can even make up to 24 cookie sandwiches if you use a smaller cookie scoop for little mini cookie bites.

Ingredients

Vanilla cake mix
Vegetable oil
Eggs
Vanilla extract
Sprinkles
Unsalted butter
Marshmallow fluff

Handy Kitchen Tools

How to Make Confetti Cookies

Preheat the oven to 375°F/190°C and line a baking sheet(s) with parchment paper.

In a large bowl, mix the dry cake mix, eggs, oil, vanilla extract, and ½ cup sprinkles together until incorporated.

This should create a thick batter. It won't be as thick as traditional dough, but won't be as thin as a cake batter.

Use a small cookie scoop to make an even number of balls on the prepared baking sheet(s) leaving at least 2" between each ball of dough.

Bake the cookies for 10-12 minutes or until the edges begin to brown.

Remove from the oven and allow to cool for 5 minutes on the baking sheets before moving to a wire rack to finish cooling.

How to Make Marshmallow Icing

In a large bowl, add the marshmallow fluff and butter and beat until smooth.

Add the powdered sugar into the mixture a little at a time beating between each addition until smooth.

The icing should not be stiff but fall into a ribbon pattern.

How to Assemble Confetti Sandwich Cookies

Using the same sized cookie scoop as used for the cookies above, add a scoop of icing on top of half the cooled cookies.

Top each with a second cookie.

Pour the remaining sprinkles into a shallow bowl, and roll each cookie on its sides to coat the outside with extra sprinkles.

Cookies can be served at room temperature or chilled and served cold or frozen.
