Begin by gathering your 3 Ingredient Reese’s Fudge components: Reese’s Peanut Butter Cups, sweetened condensed milk, and chocolate chips. Unwrap the Reese's and chop them into small pieces.

In a medium saucepan over low heat, combine the sweetened condensed milk and chocolate chips. Stir continuously for about 3-5 minutes until melted and smooth.

Once smooth, add the chopped Reese’s Peanut Butter Cups and fold into the mixture for another 1-2 minutes.

Prepare an 8x8 inch baking dish by lining it with parchment paper. Pour the fudge mixture into the dish and smooth the top with a spatula.

Place the fudge in the fridge and let it chill for about 2 hours or until firm.

After setting, remove the fudge from the refrigerator and lift it out of the pan using the parchment paper. Slice into squares or rectangles.
