This is one of my mom's recipes. It's a quick dessert for unexpected guests (or an unexpected sweet tooth) because it's easy to keep all of the ingredients on hand.
1 refrigerated pie dough crust
1 square (oz) semi sweet chocolate
1 stick butter
1 cup sugar
1/3 cup flour
2 eggs beaten
1 tsp vanilla
Melt butter and chocolate over low heat. Turn off heat and add the sugar then the flour then the vanilla. Mix a little of the chocolate mixture into the eggs to temper then add eggs into the chocolate. Pour mixture into prepared pie crust (do not prebake). Bake on 350 for 30 minutes. Great with ice cream!
