Pudding Fudge

1 (3.5 ounce) package non-instant chocolate pudding mix

⅓ cup white sugar

½ cup brown sugar

½ cup heavy cream

1 tablespoon butter

Generously butter a small pan.

Combine pudding mix, white sugar, brown sugar and cream in a large microwave-safe bowl; stir well to combine. Microwave on high until it boils, about 4 minutes. Continue to boil in microwave 3 minutes more. Stir in butter and beat until mixture begins to thicken. Spread into prepared pan and allow to cool completely before cutting into squares.
