Preheat oven to 350 degrees Fahrenheit (175 degrees Celsius). Grease a muffin tin or use paper liners.

In a large bowl, whisk eggs with oil and sweetener (if using).

Stir in mashed sweet potato and chopped broccoli.

Add flour, salt, cinnamon, and any optional spices or add-ins.

Mix until just combined. Batter will be thick.

Spoon into muffin cups.

Bake for 22–25 minutes, until golden and set. Toothpick should come out clean.

Let cool for 10 minutes before removing from pan.
