Parmesan cheese and ham muffins

This one of my mom's piéces de résistance, it's basically a Mediterrenean addition to the basic muffin recipe. It makes a great party food or snack.

Ingredients:

2 eggs
2 spoonfuls of sugar
1 deciliter of seed or rice oil
2 spoonfuls of parmesan
1 dl of milk
1 teaspoon of butter
100 g. of ham in small pieces
Flour as needed
a sachet of baking powder

Beat the eggs, sugar and oil together. Add parmisan, milk, butter and ham and mix well. Add flour through sieve and baking powder and mix as little as possible. Put mixture in muffin cups andbake at 180 celsius for 15 minutes.
