Peanut Butter Oreo Fudge

Prep Time10 minutes mins

Cook Time5 minutes mins

Total Time15 minutes mins

Servings: 16 servings

Ingredients

• 2 cups semi-sweet or milk chocolate chips (choose based on how sweet you like it)
• 1 can (14 oz) sweetened condensed milk
• 1/2 cup creamy peanut butter (no-stir style works best)
• 1 teaspoon pure vanilla extract
• 1/4 teaspoon fine sea salt (skip if using salted peanut butter)
• 16–18 Oreo cookies, roughly chopped (plus 2–3 extra for topping, optional)
• 1 tablespoon butter (optional, for extra gloss)
• Flaky sea salt for finishing (optional but delicious)

Instructions

• Prep the pan. Line an 8x8-inch baking pan with parchment paper, leaving overhang on two sides to lift the fudge out later. Lightly mist the parchment with nonstick spray if you want super clean edges.
• Chop the Oreos. Roughly chop the cookies so you get a mix of chunks and smaller bits. Set aside 2–3 chopped cookies for the top if you like a pretty finish.
• Melt the base. In a medium saucepan over low heat, add the chocolate chips, sweetened condensed milk, peanut butter, and butter (if using). Stir constantly until the mixture is smooth and glossy. Keep the heat low to avoid scorching.
• Flavor it. Remove from heat and stir in vanilla and sea salt. Taste carefully (it’s hot) and adjust the salt if needed.
• Fold in cookies. Let the mixture cool for 1–2 minutes so it’s not piping hot, then fold in most of the chopped Oreos. Don’t overmix—you want visible swirls and chunks.
• Spread and top. Scrape the fudge into the prepared pan. Smooth the top with a spatula. Sprinkle the reserved Oreo pieces over the surface and gently press them in. Add a light pinch of flaky sea salt for contrast.
• Set the fudge. Refrigerate for at least 2–3 hours, or until firm enough to slice. For best texture, aim for 4 hours or overnight.
• Slice cleanly. Lift the fudge out using the parchment. Use a warm, sharp knife (run under hot water and wipe) to cut into small squares. This stuff is rich, so 1-inch pieces go a long way.

What Makes This Special

This fudge lands the perfect balance: smooth peanut butter base with crisp Oreo pieces in every bite. It uses sweetened condensed milk for fail-proof texture, so it sets up creamy without getting crumbly.

The recipe comes together in about 15 minutes, and the rest is just chill time. It’s flexible, too—you can swap in different cookies, drizzle with chocolate, or add a pinch of sea salt to take it over the top. Best of all, it’s no-bake and beginner-friendly.

How to Store

• Refrigerator: Store in an airtight container for up to 1 week.Separate layers with parchment to prevent sticking.
• Room temperature: If your kitchen is cool, it can sit at room temp for 1–2 days. Warmer rooms may make it softer.
• Freezer: Freeze in a sealed container for up to 2 months. Thaw in the fridge for best texture.Avoid frequent thaw/refreeze cycles to prevent sugar bloom.

Health Benefits

This is a dessert, so think “treat” first. That said, there are a few upsides in the mix. Peanut butter brings plant-based protein, healthy fats (mostly monounsaturated), and vitamins like E and B6.

Cocoa in chocolate offers antioxidants, which can support heart health. A small square can be satisfying thanks to the fat and protein, which may help curb the urge to overdo it. Still, the sugar content is high, so keep portions modest if you’re watching your intake.

What Not to Do

• Don’t use natural, oily peanut butter that separates.It can make the fudge greasy and soft. Stick to no-stir creamy peanut butter.
• Don’t rush the melting. High heat can scorch chocolate and cause it to seize. Low and slow is the way.
• Don’t skip the salt. Even a pinch makes flavors pop and balances sweetness.
• Don’t add cookies while the mixture is too hot. The cream filling can melt out and the texture gets messy.Give it a minute to cool.
• Don’t overmix after adding Oreos. You want pockets of crunch, not pulverized crumbs.

Variations You Can Try

• White Chocolate Base: Swap the chocolate chips for white chocolate chips for a sweeter, creamier base. Add an extra pinch of salt.
• Marble Swirl: Hold back 2 tablespoons of peanut butter. Dollop on top after spreading the fudge and swirl with a toothpick.
• Chunky Peanut Butter: Use crunchy peanut butter for added texture, or fold in 1/3 cup roasted peanuts with the Oreos.
• Gluten-Free: Use certified gluten-free sandwich cookies and check your chocolate label.
• Dark and Salty: Use 60–70% dark chocolate chips and finish with flaky sea salt for a bolder bite.
• Espresso Boost: Stir in 1 teaspoon instant espresso powder for deeper chocolate flavor.
• Peanut Butter Cup Overload: Fold in chopped mini peanut butter cups along with the Oreos.
• Holiday Spin: Add crushed peppermint candies on top for a winter touch, or colorful sprinkles for birthdays.

FAQ

Can I make this in the microwave?

Yes.

In a large microwave-safe bowl, heat the chocolate chips, sweetened condensed milk, peanut butter, and butter in 20–30 second bursts, stirring between each, until smooth. Keep the power at medium to avoid scorching. Stir in vanilla, salt, and Oreos, then proceed as usual.

What if my fudge is too soft?

It may need more chill time.

If it’s still too soft after 4 hours, your peanut butter may have been too oily, or the kitchen too warm. Freeze the pan for 30–45 minutes before slicing. Next time, use no-stir peanut butter and consider adding an extra 1/4 cup chocolate chips for a firmer set.

Can I reduce the sweetness?

Use dark chocolate chips, add a bit more salt, and limit the Oreo mix-ins slightly.

You can also stir in 2 tablespoons of cocoa powder with the melted base for a bittersweet edge.

Is there a dairy-free version?

Yes. Use dairy-free chocolate chips and a dairy-free sweetened condensed milk (often coconut-based). Make sure your cookies and butter substitute are also dairy-free.

The set may be slightly softer, but still delicious.

How small should I cut the pieces?

Fudge is rich. Aim for 1-inch squares or even smaller. For gifting, 24–36 bite-sized pieces from an 8×8 pan is a good target.

Can I make it ahead for a party?

Absolutely.

Make it up to 3 days in advance and keep it refrigerated in an airtight container. Slice just before serving for the cleanest edges.

Do I need to butter the parchment?

Not required, but a light spray helps if you want very smooth sides and easy release. The parchment overhang is the real key to lifting it out cleanly.
