Cheesecake brownies with a deep, fudgy base and tangy creamy topping come together for a mashup that’s as pretty as it is delicious. These bars look fancy and taste even better, combining chocolatey goodness with that classic cheesecake tang in every bite.
The first time I made these, my kiddo wanted a creamy-chocolate treat. We had the best time swirling the layers, making wild patterns. Now it’s our thing—and friends are always curious how we get those fancy swirls.
Dreamy Ingredients
- Sour cream: boosts the cheesecake flavor with a gentle tang and creaminess. Pick a thick style for extra yumminess.
- Cream cheese: makes the swirl rich and smooth. Stick to full-fat blocks, nice and soft before mixing.
- All purpose flour: holds everything together. Use any kind you’ve got—bleached or unbleached both work.
- Salt: lifts up every other flavor. Fine sea salt works great for even mixing.
- Vanilla extract: adds warm sweetness. Real vanilla is worth it if you have it handy.
- Eggs: keep the bars standing strong. Large eggs at room temp blend in best.
- Unsweetened cocoa powder: lets the chocolate notes really shine. Dutch process makes it super smooth if you can find it.
- Granulated sugar: sweetens up both layers. I go with fine sugar so it melts easily.
- Unsalted butter: brings fudginess and rich flavor. Use fresh for the tastiest bars.
- Unsweetened baking chocolate: gives the whole thing a chocolate punch. Look for bars that smell intensely chocolatey and snap cleanly.
Simple Steps
- Cool before slicing:
- Pop the whole pan in the fridge for at least four hours. Cold bars slice up looking extra neat.
- Time to bake:
- Slide your pan into an oven at three-fifty. The top should look just barely puffed and lose that shiny look after fifty to fifty-five minutes. The edges will turn golden. Let it cool before cutting.
- Get those layers swirled:
- Pour the cheesecake mix right over the brownie batter. Zigzag a knife or skewer through everything. Don’t swirl too much or it’ll get messy.
- Mix in cheesecake extras:
- Beat in eggs one at a time, toss in sugar and a splash of vanilla. Beat it all until it’s silky and smooth, because lumps aren’t fun.
- Make the cheesecake layer:
- Grab a clean bowl and use your mixer to whip up the cream cheese and sour cream until it’s super smooth and lump free.
- Add flour:
- Carefully fold in the flour by hand so you don’t make the brownies tough. Just mix until you can’t see dry bits, then smooth the batter into your lined pan.
- Stir up the brownie mix:
- Mix in sugar and cocoa powder to your melted chocolate. Stir in eggs and vanilla, then a pinch of salt. It’ll look a little rough but just keep going until smooth.
- Melt chocolate and butter:
- Chop chocolate, toss with butter in a big microwaveable bowl. Zap for thirty seconds at a time, stirring in between. Stop once it’s glossy and totally combined.
- Prep your baking pan:
- Line a nine-inch square baking pan with foil, then spritz with nonstick spray. This makes it easy to pull out bars and keeps cleanup a breeze.

The swirl is the best moment for me. Every pan is a surprise—some look like marble art, and no matter how many times we bake them, my kids always want to do the swirling part.
Chill Storage Tips
For fresh bars, tuck them in a sealed container in the fridge for three days. Stack with parchment so nothing sticks. Going long-term? Wrap each piece well, freeze, then thaw or snack them cold right from the fridge. That’s my sneaky treat.

Easy Swaps
No sour cream? Use plain Greek yogurt that’s just as thick, or swap mascarpone for a richer taste. Gluten-free friends can trade the flour for a cup-for-cup blend. Skip whipped cream cheese, though—it’ll mess up the swirl’s smoothness.
Fun Ways to Serve
Pop these bars on a plate straight from the fridge, or dress them up with fresh berries. Big party? Add a plop of whipped cream and some chocolate curls. They even make cute gifts if you wrap them with parchment and a bit of ribbon.
Where This Treat Comes From
Cheesecake brownies started popping up in American bakeries late last century, when folks wanted the best of both desserts. The classic swirl comes from old European cakes, turning every batch into a unique work of delicious art.
FAQs About the Recipe
- → Which pan should I grab?
Pick out a 9x9-inch square dish for the best results. Both brownie and cheesecake parts bake up just right and you get the ideal thickness every time.
- → How do I make the swirls look smooth?
Let your eggs and cream cheese hang out on the counter to warm up. Spread the cheesecake blend on top, then take a butter knife and drag it through both layers—do it gently for pretty marbling.
- → Is it OK to swap in semi-sweet chocolate?
Semi-sweet works great! Don’t forget to use a little less sugar since it’s already pretty sweet.
- → How do I melt the butter and chocolate?
Drop them into a microwave-safe bowl. Heat in 30-second chunks, stirring well after each time, until it’s all silky smooth.
- → Why should I chill the bars first?
Chilling keeps the layers firm so you cut perfect squares and it lets all the flavors blend together too.
- → How do I keep these bars fresh?
Keep them in a sealed container in the fridge—they’ll be tasty for around three days. If that’s not enough time, freeze the bars to keep them longer.
