Ultimate Reeses Cheesecake Brownie Bars!
1 pkg. brownie mix
1 pkg. (8 oz.) cream cheese
2 tbsp. butter, softened
1 can (14 oz.) sweetened condensed milk
1 tbsp. cornstarch
1 tsp. vanilla
Reeses candy bars
Preheat oven to 350*. Mix brownies according to package. Spread in greased 9x13 pan. Chop up as many reeses candy bars as you think best for your taste. (save the reeses pieces for later) Beat cream cheese, butter and cornstarch until fluffy. Beat in milk, egg, and vanilla until smooth. Stir in your chopped candy bars. Spoon cheesecake batter on top of the brownie batter. Bake 40-45 minutes. Cool. Cut into bars and drizzle with peanut butter and chocolate candy melts and sprinkle reeses pieces on top of that. Keep refrigerated....if you have any left:-)
