Preheat oven to 350F. Grease muffin tin or line with muffin liners.
In a large bowl, mix together eggs and cream until well combined.
Add remaining ingredients and mix well.
Spoon batter into the prepared muffin tin, about 3/4 full. Transfer muffin tin to oven and bake for 18 to 20 minutes. Transfer muffin tin to a wire rack and let cool completely.
Use a pairing knife to run around the edges of the frittatas to release them from the muffin tin.
The frittatas can be frozen up to a month. Reheat in the microwave before serving.
