Ingredients
Use exact amounts for best texture and flavor.
- 2 cups semi-sweet chocolate chips
- 1 (14 oz / 395 g) can sweetened condensed milk
- 1 cup creamy peanut butter
- 1 teaspoon vanilla extract
- 16 Oreo cookies, roughly chopped
- Pinch of salt (optional, but balances sweetness)

Step-by-Step Instructions
Follow these steps carefully for smooth, firm, sliceable fudge.
Step 1: Prepare the Pan
Line an 8×8-inch (20×20 cm) square pan with parchment paper, leaving some overhang on the sides. This makes lifting the fudge out easy once it sets.
Step 2: Melt the Base
In a medium saucepan over low heat, add the chocolate chips and sweetened condensed milk. Stir constantly with a spatula or wooden spoon until the chocolate is fully melted and the mixture looks smooth and glossy. Do not increase heat, as chocolate can scorch easily.
Step 3: Add Peanut Butter and Flavor
Remove the pan from heat. Stir in the peanut butter, vanilla extract, and salt if using. Mix until fully combined and creamy with no streaks left.
Step 4: Fold in the Oreos
Add the chopped Oreo cookies and gently fold them into the fudge mixture. Try not to overmix so the cookie pieces stay chunky and visible.
Step 5: Transfer and Smooth
Pour the mixture into the prepared pan. Use a spatula to spread it evenly into the corners and smooth the top.
Step 6: Chill Until Firm
Refrigerate for at least 2 to 3 hours, or until the fudge is completely set and firm to the touch.
Step 7: Slice and Serve
Lift the fudge out using the parchment paper. Place on a cutting board and slice into small squares using a sharp knife. Clean the knife between cuts for neat edges.

How to Serve
Peanut Butter Oreo Fudge is best served slightly chilled so the pieces stay firm and clean. For parties, cut into small bite-size squares since the fudge is rich. It pairs well with coffee, milk, or hot chocolate. You can also place pieces in cupcake liners for a neat, bakery-style look. For gift boxes or holiday trays, layer parchment paper between rows so the pieces do not stick together.

Storage Instructions
Store fudge in an airtight container in the refrigerator for up to 10 days. If stacking pieces, place parchment paper between layers. For longer storage, freeze the fudge in a sealed container or freezer bag for up to 2 months. Thaw overnight in the refrigerator before serving. Avoid storing at room temperature for long periods, especially in warm weather, as the fudge may soften and lose its shape.
Helpful Tips
Use low heat when melting chocolate to prevent grainy texture. Stir constantly and remove from heat as soon as smooth. Choose creamy peanut butter for best blending; natural peanut butter with oil separation may cause texture issues. Chop Oreos by hand instead of crushing them to keep visible cookie chunks. If your fudge feels too soft after chilling, give it more time in the fridge rather than adding extra chocolate, which can change the flavor balance.
Variations
You can easily customize this fudge to suit different tastes. For extra crunch, mix in chopped peanuts along with the Oreos. If you prefer white chocolate, replace semi-sweet chips with white chocolate chips for a sweeter, creamier base. To boost chocolate flavor, drizzle melted chocolate over the top after setting. For a layered look, press crushed Oreos into the pan first, then pour the fudge mixture on top and smooth before chilling.

FAQs
Can I make this fudge without a stove?
Yes. You can microwave the chocolate chips and condensed milk in a microwave-safe bowl in 30-second intervals, stirring each time, until fully melted. Then add peanut butter, vanilla, and Oreos as directed.
Why is my fudge too soft?
Soft fudge usually means it needs more chilling time or the mixture was not heated enough to fully melt and combine. Refrigerate longer before slicing. Also make sure measurements were accurate.
Can I use crunchy peanut butter?
You can, but it will change the texture and make slicing less clean. Creamy peanut butter gives the smoothest, most consistent results.
Do I need to grease the pan?
Parchment paper is enough. Greasing is not required and can make the bottom greasy.
Can I double the recipe?
Yes. Use a 9×13-inch pan and double all ingredients. Chill time may increase slightly due to thickness.
