When I see juicy blackberries at the store, I can't wait to make this chilled, creamy treat. Sweet berries go so well with the airy filling and crisp graham cookie base, it's always gone fast at my cookouts.
I mixed up a pan of this last July 4th and everyone instantly wanted seconds. The fruity layer and whipped center made it a hit—now it's on deck every summer.
Irresistible Ingredients
- Salted butter: makes the crumb base come together with a rich taste Fresh butter works best
- Graham cracker crumbs: give that classic crunchy bottom Use a food processor if you want a homemade vibe
- Heavy whipping cream: keep it cold so you get a fluffy finish It turns the filling into a mousse texture
- Sour cream: gives a gentle tang and keeps the filling creamy Full-fat makes it extra smooth
- Powdered sugar: keeps the inside sweet and soft Give it a sift so you don't get lumps
- Cream cheese: needs to be soft and at room temp for a pillowy base Use full-fat for mega creaminess
- Cornstarch: thickens the fruit mixture so you can slice the bars easily Make sure it's not expired
- Water: mixes with the cornstarch for a silky fruit topping Plain tap water’s good
- Ground cinnamon: just a hint in the topping to add a cozy flavor
- Vanilla extract: laces both the fruit and filling with sweet notes Go for pure vanilla if you can
- Granulated sugar: makes the crust sweet and controls the tartness in the berries Use a superfine white for best mixing
- Fresh blackberries: grab berries that are plump and glossy for the best color and jammy taste

Every summer, blackberries call my name. Whenever we turned them into this sweet treat, my kids and I would eat as many as we could on our way home from picking. Purple fingers were just part of the fun!
Smart Storage Advice
Cover tightly and stash leftovers in your fridge for up to 5 days. Want to store longer? Pop it in the freezer for as long as 3 months. For the cleanest slices, cut while semi-frozen and let them soften just a touch before digging in.
Swaps and Changes
No fresh blackberries around? Grab frozen ones or toss in some raspberries or blueberries. You can also swap in vanilla wafers or digestive cookies for the base. If using sweeter berries, taste and tweak your sugar.
How to Serve
Cut big squares for a group, or build cute single servings in mason jars for fun. Add a dollop of whipped cream or a few chopped toasted almonds at the end for a pretty finish.

Recipe FAQs

Go ahead and use frozen or mixed berries when fresh ones aren't handy. You'll just want to simmer them a bit longer if they're really icy.

Pop any leftover cheesecake in the fridge for up to a week. You can also freeze it for three months, then just let it thaw in the fridge overnight before serving.

A 9x13 inch dish is spot on. It's big enough for easy cutting and helps everything set just right.
