Preheat your oven to 350 degrees.
In a bowl, whisk together your yogurt and water until well combined.
Add the dry cake mix to the yogurt mixture. Do not use any other ingredients mentioned on the cake mix box.
Take a paper towel and moisten it with vegetable oil. Use the greased paper towel to coat the muffin pan, ensuring the muffins will easily pop out after baking.
Using a cookie scoop, fill the baking cups halfway. Keep in mind that these muffins rise generously during baking.
Bake for about 15-22 minutes, depending on your oven. To check for doneness, insert a toothpick into the center of a muffin; if it comes out clean, the muffins are ready.
Serve and enjoy these guilt-free delights!
