Preheat oven to 400 degrees.
Mix the two ingredients together. Don’t add anything else that may be mentioned on the box, such as eggs, oil, or water.
The mixture will be very thick, so you might be tempted to add in other things to make the batter smoother. Do NOT do this!
Place batter into a 12-cup muffin pan lined with baking cups or sprayed with nonstick spray. Place pan in the oven, and bake for 20 minutes. Enjoy!
