Grandma's famous baked stuffed mushrooms

This blog is only recipes on baking...since I'm not much of a fan of cooking, BUT I've been getting requests to post the recipe to my grandma's famous Thanksgiving stuffed mushrooms..so I asked her for the recipe. Some of her measurements were done by eyeballing it since she never uses measuring cups, lol, but I converted her system into regular measurements. Please let me know how yours turn out if you make them :)


Ingredients:
20 medium whole mushrooms
handful or 1/3 cup Italian style bread crumbs
3 tbsp butter
1 tbsp oil
1 cup shredded mozzarella cheese
1 clove garlic
(1/3 cup cooked spinach if desired)

Directions:
1.Preheat oven to 350 degrees
2.Remove stems of each mushroom(to base) and set the mushroom tops/caps to the side
3.Chop mushroom stems into small pieces
2.Get out a pan and set burner to medium high
3.Once pan is hot put in 2 tbsp of butter and 1 tbsp olive oil
4.Crush garlic and stir in pan with the butter mixture for about 4 minutes. make sure not to burn garlic.
5.Throw chopped mushroom stems into pan, make sure they are covered in butter and all the way cooked through
6.Turn off heat and set the pan onto a COOL burner.
7.Grease a cookie sheet and place mushroom tops face up.
8.Add bread crumbs to the pan of mushroom stems(make sure they are Italian style..regular will taste bland), combine thoroughly. (if the mixture seems dry add a tiny bit more melted butter or even chicken broth)
9.Add in 3/4 cup shredded cheese (the cheese should melt slightly after combined with stuffing mixture)
10.Fill each mushroom cap with stuffing mixture (about 1-1.5 tablespoons per mushroom)
11.Top each mushroom with a pinch of shredded mozzarella
12.Melt remaining tbsp of butter and brush the top of each mushroom
13.Place into oven for 15-25 minutes or until cheese is melted and bubbling on the top of each mushroom
