Surprise Fudge

Happy Nurses' Week! By popular demand I made my "surprise" fudge to show my appreciation for all the great ladies I work with. When I saw a recipe for avocado fudge on AllRecipes last year, I was too curious not to try it. I make it a rule not to tell people the secret ingredient until they've tasted it, you all will have to take my word for it. It's delicious!
Note: This reflects 1/2 the original recipe. The whole thing makes WAY too much.

Surprise Fudge 

1 ripe avocado, peeled and pitted
1/4 c melted butter
1/4 Baileys
1 c unsweetened cocoa
3 c confectioners sugar
3/4 c semi-sweet chocolate chips, melted
1/4 c white chocolate chips, melted

Puree the avocado and butter in blender or with immersion blender. Be sure to blend very well, it should be uniform color and texture:

Place mixture in saucepan over low heat. Add Baileys and cocoa powder, stir until very well mixed.
Stir in sugar 1 cup at a time, mixing completely after each addition.
Add melted chocolates, remove from heat as soon as mixed.
Pour in an 8x8 pan lined with parchment paper. cool completely. Cut into squares.
