If you love cheesecake but want to keep things low carb, this one is for you. My keto blackberry lime velvet cheesecake is creamy, fresh, and easy to put together.
The lime gives it a bright flavor, and the blackberry swirl on top makes it look really nice too.

It is keto friendly, which means you can enjoy a proper dessert without worrying about your carb count for the day.
I like making this when I want something that feels a little special but does not take much effort.
You do need to chill it for a few hours, so I usually make it ahead of time and let the fridge do the rest.

Tips
Soften Your Cream Cheese Fully
Take the cream cheese out of the fridge at least an hour before you start. It needs to be soft all the way through, not just on the outside.
From my experience, cold cream cheese never beats out smooth and you end up with tiny lumps that won’t go away no matter how long you mix.
If you forget, cut it into small cubes and let them sit on the counter for about 30 minutes to speed things up.
Keep the Heavy Cream Cold
This is a no bake cheesecake, so the whipped cream is what gives it structure and that light, velvety feel. Cold cream whips up faster and holds firm peaks much better.

My favorite trick here is to chill the bowl and the beaters in the freezer for 10 minutes before I start. It makes a real difference.
Stop whipping as soon as you see firm peaks, because going too far turns the cream grainy and it won’t fold in smoothly.
Fold, Don’t Stir the Cream In
When you add the whipped cream to the lime filling, use a spatula and fold gently from the bottom up. You want to keep all that air you just whipped in.
I’ve found that stirring hard or fast knocks the air right out, and then the filling turns dense instead of fluffy.
Keep folding just until you don’t see any white streaks left, then stop.

Frequently Asked Questions
Can I use frozen blackberries instead of fresh?
Yes, frozen blackberries work great here since you are mashing them anyway. Just let them thaw first and drain off any extra liquid so the layer does not turn runny.
The chia seeds will still help thicken everything into a nice jammy texture.
