This recipe is from the Pioneer Woman. It makes a very sweet, mousse-like chocolate pie. It was easy to make, but it takes a little bit of time at the mixer. It doesn't have very many ingredients either.
4 oz. unsweetened baking chocolate
2 sticks of butter
1-1/2 c. sugar
1 t. vanilla
1 pie shell
Melt the chocolate in the microwave. Set aside to cool. Beat the butter and sugar until fluffy. Once cool, drizzle the chocolate in the butter sugar and beat. Add the vanilla. Then add in one egg, beating for 5 minutes. Then repeat until all the eggs have been added (20 minutes). Pour into the pie shell and refrigerate.
