On Christmas Eve I made these stuffed mushrooms.  The cayenne gives them a little kick...my mom noticed but it didn't phase my 4-year old.   

Stuffed Mushrooms
Annie's Eats

24 whole fresh buttom mushrooms
3-4 cloves garlic, coarsely chopped
2 tsp. vegetable oil
8 oz. cream cheese, softened
1/4 cup grated Parmesan cheese
1/4 tsp. pepper
1/4 tsp. onion powder
1/4 tsp. cayenne pepper
Bread crumbs and minced fresh herbs, for garnish (optional)

Preheat oven to 350 degrees.  Lightly grease a baking sheet with cooking spray.  Clean mushrooms with a damp paper towel.  Carefully remove the stems from the mushroom caps, setting the caps aside for later.  Add the stems to the bowl of a food processor.  Add the garlic to the food processor as well, and pulse in brief bursts until the mushroom stems and garlic are finely chopped.

Heat the oil in a large skillet over medium heat.  Add the chopped mushroom stems and garlic and cook until all the moisture has disappeared, about 5-7 minutes.  Lower the heat to medium-low.  Stir in the cream cheese, Parmesan cheese and spices.  Stir together until the mixture is smooth and creamy; remove from heat.  Using a small spoon, fill each mushroom cap with a generous amount of filling.  Arrange the mushroom caps on the prepared baking sheet.  Top with bread crumbs, if desired.  Bake for 20 minutes or until the mushrooms are hot and liquid starts to form under the caps.  Transfer to a serving platter, garnish with fresh herbs if using and serve immediately.
