It's about to be Shavuos, so, it's time for cheesecake. Here's the recipe I usually use. It's a sour cream & cottage cheese one rather than the cream cheese base I usually see.

You'll need:

2 graham cracker pie crusts
16 oz sour cream (1 regular-sized container)
16 oz cottage cheese (1 regular-sized container)
3 eggs
~1.5 cups sugar - you can toggle this
1/4 cup flour (can use cornstarch for GF)
1 tsp vanilla

Preheat oven to 350 F

Dump all the ingredients into a large bowl. Mix a bit and then immersion-blend. Pour into the graham cracker crusts* and bake for about an hour.

* At this point, feel free to swirl in different flavors. I've used nutella, mocha (coffee with chocolate), and various jams.
