A Little Slice of Heaven

1 1/4 cups Nutella
10 oz. chocolate, milk, dark or semi-sweet
1 tablespoon salted butter
1 - 14oz. can sweetened condensed milk
1 teaspoon vanilla extract

Add chocolate and Nutella to a large mixing bowl and microwave in 30 second increments, stirring after each, until smooth. Add the butter and stir until melted. Add the sweetened condensed milk and vanilla, stirring until well combined. Mixture will be very thick. Pour mixture into an 8x8-inch baking pan lined with wax paper. Smooth the fudge so it's even. Refrigerate for at least 2 hours or overnight until set. Cut and serve.
