Melt the chopped chocolate with the butter over low heat in a medium saucepan. Remove from the heat to allow it to cool a bit.
Stir brown sugar, whisked eggs and vanilla into the chocolate mixture just until the yellow disappears.
In a mixing bowl, sift together flour, baking powder and salt.
Stir flour mixture into the saucepan by hand.
Take about 1/2 cup of the batter and spread it into a buttered cast iron skillet.
Place 12 Snickers Peanut Butter Squares on top of the batter, then pour the remaining batter over the top of the candies, spreading evenly.
Place the skillet in a preheated 350 degree oven and bake for about 25-30 minutes, checking at 25.
Garnish with ice cream, chopped squares, caramel and chocolate sauce. Say Grace and enjoy!
