Preheat the oven to 200° degrees. Line a baking sheet with parchment paper.

With an electric hand mixer, whip egg whites on low speed, increasing to medium speed until the egg whites are white and foamy.(You can also make this in the large bowl of a stand mixer with the whisk attachment.)

Add cream of tartar and half of the sugar. Continue whipping until egg whites begin to thicken and soft peaks form.

Gradually add the remaining sugar and vanilla. Continue to whip on high for several minutes, until stiff peaks form.

Add the sprinkles and gently fold to combine.

Next, add the different colors of your food coloring gel to opposite ends of the bowl. Gently swirl together.

Place egg white mixture in a large piping bag fitted with a large star tip or closed star tip.

Pipe the meringue onto the prepared baking sheet using a circular motion to create small rounds.

Place in oven and bake for 2 hours. When finished baking, turn the oven off and open it slightly. Leave the baked meringues in the oven while they cool (about 1 hour). Remove from oven and enjoy!
