Peanut Butter Cup Cheesecake Fudge is a sweet treat that combines the creamy richness of cheesecake with the classic flavors of peanut butter cups. This fudge is smooth and dense, packed with chunks of peanut butter cups that give it a fun, chocolatey crunch inside every bite. It’s like having a slice of cheesecake and your favorite candy all rolled into one.
I love making this fudge when I’m looking for something special but don’t want to spend hours in the kitchen. It’s simple to prepare, and the peanut butter and cream cheese create a perfect balance that’s just right—not too sweet and not too heavy. I always keep some in the fridge for a quick snack or to share with friends because it feels extra special but is easy to enjoy anytime.
My favorite way to serve this fudge is chilled, cut into small squares. It’s perfect for parties or just a little treat after dinner. Plus, it holds up well, so you can make it ahead of time and have it ready when guests stop by. If you like peanut butter cups and cheesecake, this fudge is the easiest way to get the best of both worlds in a bite-sized dessert!
Key Ingredients & Substitutions
Semi-Sweet Chocolate Chips: These give the fudge its chocolate base. If you prefer, use dark chocolate chips for a slightly less sweet taste or milk chocolate chips for extra creaminess.
Sweetened Condensed Milk: This adds sweetness and a smooth texture. If unavailable, you can make your own by simmering milk and sugar slowly until thickened, but it takes longer.
Peanut Butter: Creamy peanut butter blends well here. If you want a nut-free version, try sunflower seed butter, but it will change the flavor a bit.
Cream Cheese: This gives the fudge a cheesecake feel and creamy texture. Make sure it’s softened to avoid lumps. For a dairy-free option, coconut cream cheese works well.
Peanut Butter Cups: Chopped pieces add texture and bursts of flavor. If you can’t find them, peanut butter chips or chopped Reese’s Pieces can be a good alternative.
How Do You Create Those Perfect Swirls in Peanut Butter Cup Cheesecake Fudge?
Swirling the top layers gives the fudge a beautiful marbled look and mixes flavors just right. Here’s how to do it easily:
- After pouring the cream cheese layer over the chocolate layer, warm the remaining peanut butter until soft but not hot.
- Drizzle the softened peanut butter evenly over the cream cheese layer.
- Use a knife or skewer to gently swirl the peanut butter and cream cheese together in a figure-eight or circular motion.
- Don’t overmix—stop as soon as you see pretty swirls. This keeps the layers distinct and eye-catching.
- Chill immediately to set the swirl pattern before cutting.
My tip: Warming the peanut butter makes swirling smooth and easy. If it’s too stiff, it won’t spread well, and if too hot, it can melt the cream cheese layer.
Equipment You’ll Need
- 8-inch square pan – I recommend this size to keep the fudge thick and easy to cut into squares.
- Parchment paper or aluminum foil – makes lifting out the fudge simple and mess-free.
- Microwave-safe bowls – for melting chocolate and peanut butter quickly and evenly.
- Mixing bowls – to beat the cream cheese and fold in ingredients smoothly.
- Spatula or butter knife – helps spread and swirl the layers for a pretty finish.
- Measuring cups and spoons – for accurate ingredient portions.
Flavor Variations & Add-Ins
- Use milk or dark chocolate instead of semi-sweet for different flavor profiles.
- Add a teaspoon of vanilla extract or a pinch of cinnamon to the cream cheese mixture for extra flavor.
- Mix in chopped nuts like peanuts, almonds, or walnuts for crunch and added richness.
- Replace peanut butter cups with chopped Reese’s Pieces or M&Ms for variety and color.

How Much Time Will You Need?
This recipe takes about 20 minutes to prepare, plus at least 4 hours of chilling time to let the fudge set properly. It’s best to prep it ahead and refrigerate so it can firm up and the flavors meld wonderfully.
Step-by-Step Instructions:
1. Prepare Your Pan:
Line an 8-inch square pan with parchment paper or aluminum foil. Make sure to leave some overhang on the sides, so you’ll have an easy way to lift out the fudge later.
2. Melt the Chocolate Layer:
In a microwave-safe bowl, combine the chocolate chips, 1 cup of the sweetened condensed milk, and softened butter. Heat in 30-second bursts, stirring well after each, until everything is melted and smooth. You can also melt them gently over a double boiler if you prefer.
3. Pour the Chocolate Layer:
Spread the melted chocolate mixture evenly into your prepared pan. This will be the bottom layer of your fudge.
4. Make the Cheesecake Layer:
In a mixing bowl, beat together the cream cheese, the remaining 1 cup sweetened condensed milk, 1/2 cup peanut butter, vanilla extract, and salt. Continue beating until the mixture is smooth and creamy. Carefully fold in the chopped peanut butter cups if you’re using them.
5. Assemble and Swirl:
Spread the cream cheese mixture over the chocolate layer in the pan. In a small bowl, warm the remaining 1/2 cup peanut butter in the microwave for 20-30 seconds until soft and easy to drizzle. Drizzle this peanut butter over the cream cheese layer. Use a knife or skewer to swirl the layers together gently, creating a marbled look.
6. Chill and Cut:
Put the fudge in the refrigerator for at least 4 hours to let it set fully. Once firm, use the parchment or foil overhang to lift the fudge out of the pan. Cut it into squares, and store them in an airtight container in the fridge.
Enjoy your rich, creamy, and delicious Peanut Butter Cup Cheesecake Fudge, perfect for sharing or keeping as a special treat!
Can I Use Frozen Cream Cheese for This Fudge?
It’s best to use softened cream cheese for a smooth texture. If your cream cheese is frozen, thaw it in the fridge overnight and let it come to room temperature before mixing.
Can I Substitute Peanut Butter Cups with Another Candy?
Absolutely! You can use chopped Reese’s Pieces, peanut butter chips, or even chopped chocolate bars for a different twist. Just keep the texture in mind to maintain the fudge’s consistency.
How Should I Store Leftover Fudge?
Store leftover fudge in an airtight container in the refrigerator. It will keep well for up to 1 week. You can also freeze it for longer storage—just thaw in the fridge before serving.
Can I Make This Fudge Ahead of Time?
Yes! This fudge is perfect to make ahead. Prepare it and chill for at least 4 hours or overnight to let the flavors meld and the fudge firm up nicely.
