Preheat oven to 375ºF. Prepare a 12-cup muffin tin with liners or spray lightly with cooking spray.
Beat eggs slightly in bowl. Add sugar, oil and pumpkin and beat thoroughly for 1 minute.
Sift together dry ingredients in another bowl. Add to pumpkin mixture and mix well until smooth.
Stir in add-ins, I used mini dark chocolate chips.
Fill prepared muffin cups ⅔ full. Bake 15-20 minutes. Enjoy as muffins or frost with Black Chocolate Buttercream Icing to make cupcakes.
