Start by mixing the can of condensed milk with 1/2 cup of the white cake mix. Stir well and divide the mixture evenly between two different bowls.

Grab one of the bowls and add in a cup of Reese's peanut butter chips.

Put in the microwave for 60 seconds and remove and stir. If still lumpy, put back in the microwave for another 20 seconds. Be careful though and don't heat too much or you'll burn them.

Once melted, pour it into the parchment-lined baking dish. Smooth it out evenly.

Grab the second bowl and add in the semi-sweet chocolate chips. Repeat the microwave process and then pour the melted mixture on top of the peanut butter mixture.

Smooth it out and cover evenly.

While still slightly warm, add on the sprinkles and a T of semi-sweet and peanut butter chips and a box of Reese's Pieces, too.

Slightly push down the toppings into the fudge with your fingers.

Pop in the fridge for at least 2 hours or until firm. Remove from pan, cut, and enjoy!
