No Bake Blackberry Cheesecake is the kind of dessert I turn to when I want something impressive without having to fuss with an oven or worry about cracks. Creamy layers of slightly tangy cheesecake meet a quick homemade berry sauce that looks as lovely as it tastes. The buttery graham crust comes together in minutes and the whole thing sets beautifully in the fridge while you go about your day.
My family always requests this for Fourth of July picnics so I know it never fails to wow. The best part is sneaking a spoonful of the creamy filling while waiting for it all to chill.
Ingredients
- Fresh blackberries: provide bright flavor and juicy texture Choose plump berries that look firm and deep purple
- Granulated sugar: sweetens both crust and topping I lean toward fine baking sugar for easy mixing
- Vanilla extract: adds warm bakery notes A quality vanilla really shines in a no-bake treat
- Ground cinnamon: gives a little warmth to the topping Look for spice that smells fragrant when you open the jar
- Water and cornstarch: turn the fresh berries into a lush sauce Use fresh cornstarch for best thickening power
- Cream cheese: is the heart of the filling Go with full-fat blocks for luxe texture
- Powdered sugar: blends smoothly with the cream cheese and adds sweetness Choose one without caking agents if possible
- Sour cream: brings tang and keeps the filling light and creamy Try to avoid ultra-thick Greek style
- Heavy whipping cream: creates volume and a mousse-like texture Chill your bowl and beaters for the highest peaks
- Graham cracker crumbs: form the easy buttery crust Crush them yourself for best texture or use a trusted brand
- Salted butter: holds the crust together and brings out all the flavors A fresh stick gives the richest taste and color
Step-by-Step Instructions
- Make the Crust:
- Stir together graham cracker crumbs with sugar until well mixed Melt salted butter and mix it into the crumbs so the mixture resembles wet sand and every crumb is moistened
- Press Into Pan:
- Using a firm touch press the crust evenly over the bottom of a nine by thirteen pan Get the corners even and the surface smooth so the filling sits flat Freeze for at least ten minutes to firm it up
- Prepare Cream Cheese Mixture:
- Beat the softened cream cheese with powdered sugar vanilla and sour cream until silky with no lumps Scrape down the bowl so everything incorporates
- Whip the Cream:
- Pour cold heavy cream into a chilled bowl Use a mixer and beat until stiff glossy peaks form Stop before it turns grainy to keep the texture light
- Combine Fillings:
- Gently fold the whipped cream into the cream cheese base Use a spatula and a light hand to keep the mixture airy Stop as soon as everything looks blended
- Spread and Chill:
- Evenly smooth the filling over the chilled crust I like using an offset spatula for sharp corners Let it chill at least four hours so it sets firm and slices cleanly
- Make Blackberry Topping:
- Combine blackberries sugar vanilla cinnamon water and cornstarch in a saucepan Cook over medium heat stirring constantly until berries burst juices thicken and you have a glossy jam-like sauce Cool completely to room temperature
- Finish and Serve:
- Spread the cooled blackberry topping over the firmed cheesecake Slice with a damp knife to get neat pieces Serve chilled for the dreamiest texture

My favorite part is the way the vanilla and warm cinnamon round out the blackberries on top It reminds me of berry picking with my grandmother who would let me eat as many as I could sneak off the vine

Mix melted butter thoroughly with the graham cracker crumbs and sugar, then press the mixture firmly and evenly across the dish. Firmly chill or freeze before adding the filling for best results.

Yes, frozen blackberries work well. Use them directly from the freezer; add a few extra minutes to the simmering step to account for chilling.
