We love going to Sonic for a refreshing drink to beat the heat. There are many Sonic slush flavors they offer, but now I can easily make their favorite slushie at home.

If have made our Copycat Sonic Slushes, then you are going to love this recipe. We have even made Sonic Nerds Slushie when my kids have friends over. Everyone loves to make their own.

Ingredients

Water in a measuring cup, a measuring cup of sugar, measuring cup of ice and Kool-Aid Packets

Three mason jars filled with colorful Sonic Slushie drinks—red, blue, and orange—each with a yellow straw. The frosty texture of these icy slushies pops against the light surface.

These best are served fresh but you can store the leftovers in the freezer for 2-3 days.
