Got an ordinary day? This chocolate peanut butter cheesecake will turn it into a party. Silky peanut butter filling, a thick chocolate topping, and a crunchy Oreo base all come together for a can't-stop-eating dessert. It's secretly simple, so you can wow your friends with very little fuss. Go on, treat yourself whether it's a fancy night or just a lazy Saturday.
Made this for my brother's birthday years back, and now I can't show up to a family event without it. Even my mother-in-law, who swears she's not into rich desserts, always sneaks an extra helping.
Dreamy Ingredients
- Miniature chocolate chips: tossed into the batter for tiny gooey chocolate surprises
- Roasted peanuts and Reese’s cups: sprinkle on top for crunch and a fun look
- Milk chocolate: melts into a sweet creamy topping that feels lighter than dark chocolate
- Heavy cream: brings a velvety richness to both the creamy middle and chocolate topping
- Smooth peanut butter: go for store-bought stuff like Jif or Skippy for that perfect creamy flavor
- Cream cheese: the main dairy base—go full-fat for the nicest, creamiest result
- Oreo cookies: crushed up (filling and all) to make the awesome crunchy base
Detailed Steps
- Dress it up:
- Chill the cheesecake, then spoon ganache over the top and let it run down the sides. Add chopped Reese's and nuts before your topping firms up. Pop it back in the fridge till it's time to eat.
- Make the chocolate topping:
- Warm up heavy cream until you see a few bubbles, then pour it over half your chocolate. Wait a minute, stir until smooth, then add the rest of the chocolate and stir till shiny. Let it cool off a bit so it thickens but stays pourable.
- Let it chill out:
- Turn off the oven, crack the door, and let the cheesecake sit inside for about an hour. This avoids sudden temp changes, which can make dips and cracks. Chill in the fridge overnight for best taste.
- Bake it slow:
- Spread your batter on top of the chilled crust. Nest the pan in a bigger dish with water coming about an inch up—this keeps the insides creamy and helps stop cracks. Bake just until the outer ring is set and the middle jiggles if you shake the pan.
- Egg time:
- Add eggs one by one, barely mixing so you don't whip in too much air (that causes cracks). Use a spatula to gently fold in the mini chips.
- Whip up the filling:
- Beat room-temp cream cheese and sugar until totally smooth, about three minutes—remember to scrape that bowl. Mix in peanut butter, heavy cream, and vanilla till it looks creamy and blended.
- Crush and press the base:
- Throw whole Oreos (filling included) into a food processor and grind them down. Stir in melted butter till it clumps like wet sand. Press into the pan firmly and push a little up the sides. Chill this in the fridge while you make the filling.
- Get the pan ready:
- Wrap a 9-inch springform pan with two layers of sturdy foil, making sure it covers the sides. This keeps water out. Put parchment on the bottom and lightly coat the sides with spray so nothing sticks.

The creamy peanut butter is what really makes this one stand out. I've tried all kinds, and brands like Skippy or Jif just work best—natural peanut butter tends to separate and make it greasy. If my grandma were here, she’d give this her 'company-worthy' stamp.
Beating Cracks
Even when you do everything right, cracks can pop up. The good news is a layer of ganache covers anything up perfectly. Don’t stress if you spot a split—pushing it together usually makes it look worse. Let the topping do the work. To keep cracks at bay, let everything come to room temp first, avoid beating eggs too much, and always set your pan in water while baking.
Prep Ahead Tips
This dessert is even tastier the next day after chilling. It’s a dream for planning ahead: you can make the whole thing (ganache and all) up to three days before. For long-term storage, skip the ganache, freeze the cake wrapped tight for two months tops. When you’re ready, thaw in the fridge and top with fresh ganache and your favorite treats.
Easy Serving Ideas
Want spotless slices? Heat your knife under hot water, dry it, and cut—repeat each time. Pair with whipped cream, berries, or vanilla ice cream to go all out. Hosting a dinner? Try making mini cheesecakes in a muffin pan—same base, just bake about 20 minutes. Or, drizzle warm caramel for extra sweetness if that's your thing.

Recipe FAQs
- → What can I do to keep the cheesecake from cracking?
To prevent cracks, make sure all ingredients are at room temperature, avoid over-beating the mixture, and cook the cheesecake in a water bath for even baking.
- → Can I swap out the Oreo base for another crust?
Absolutely! A graham cracker crust or even a different cookie crust will work just as well.
- → What’s the easiest way to melt chocolate for ganache?
Warm up heavy cream until it’s bubbling, then pour it over your finely chopped chocolate. Stir until the mixture is silky and smooth.
- → How long should the cheesecake be chilled?
Let it chill for at least 5 hours, though letting it sit in the fridge overnight is even better for a proper set.
- → Any tips for getting a smooth ganache drizzle?
Make sure the ganache is slightly cooler but still runny. Use a spoon and layer the drizzle gently over the edges for more control.
- → Can smooth peanut butter be swapped for chunky?
Stick with smooth peanut butter for the best texture. Chunky peanut butter might affect the creamy consistency of the filling.
