Easy Chocolate Peanut Butter Cup Fudge

Ingredients

1 (14 oz.) can full-fat sweetened condensed milk
3 cups semi-sweet chocolate chips
1 teaspoon vanilla extract
1.5 cups diced peanut butter cups

Instructions

Line an 8×8 inch baking pan with foil, letting the sides drape over so you can easily lift out the fudge after it sets.
In a medium saucepan, combine the chocolate chips and the condenced milk. Heat on medium, stirring constantly, until the mixture is smooth. (This takes a good 20 minutes or so.)
Remove the pan from heat and mix in the vanilla and the peanut butter cups.
Pour into the lined baking pan.
Let it set in the fridge for 4 hours or at room temperature overnight.
Use a sharp knife to cut it into 1-inch squares. If the fudge is cold, let it sit out for about 20 minutes before attempting to cut.

Notes:
The original recipe uses 1 cup of walnuts. Feel free to substitute this instead of the peanut butter cups!

Tips and Substitutions

• Chocolate chips: You can use milk chocolate, dark chocolate, or even a mix depending on your preference. Semi-sweet works best for that classic rich flavor.

• Peanut butter cups: If you’re not a peanut butter fan, try chopped walnuts, pecans, or even almond butter cups for a twist.

• Vanilla extract: Don’t skip this—it enhances the chocolate flavor and adds a subtle warmth.

• Condensed milk: Full-fat is recommended for creamy fudge. Low-fat versions may change the texture.

Serving Ideas

• Perfect for holiday cookie trays or birthday dessert tables.

• Cut into small squares and serve as bite-sized treats at parties.

• Pair with a glass of cold milk or hot cocoa for the ultimate indulgence.

• Wrap in parchment paper for gifting to friends and family—it’s always a hit.

Storage and Freezing

• Store fudge in an airtight container in the fridge for up to 2 weeks.

• For longer storage, fudge can be frozen for up to 2 months. Just wrap individual squares in plastic wrap and place them in a freezer-safe container.

• Thaw at room temperature for 15–20 minutes before serving.

FAQ

Q: Can I make this fudge without peanut butter cups?
A: Absolutely! The original recipe uses 1 cup of walnuts, which gives a different but equally delicious texture. You can also try other nuts or chocolate chunks.

Q: How long does it take for the fudge to set?
A: If refrigerated, it takes about 4 hours. At room temperature, it may take overnight to fully set.

Q: Can I use sweetened condensed milk in a different size can?
A: Yes, just measure out 14 ounces if your can is larger or smaller. The key is the balance between chocolate and milk for the right texture.

Q: Why is my fudge grainy?
A: Stir constantly over medium heat until smooth. Overheating or rushing can cause the chocolate to seize, leading to a grainy texture.
