Add pitted dates to a small bowl and pour a cup of boiling water over them. Allow to soften for 5-10 minutes, then remove skins and pits.
Add cottage cheese, tahini, peeled dates, cardamom, vanilla extract, and honey to a Vitamix or food processor and blend until smooth.
Pour cottage cheese mixture into a bowl, ceramic dish, or a loaf pan and swirl some pistachio cream into it using a chopstick (optional). Cover with plastic wrap and place in the freezer for 4 hours.
Prepare Topping
Meanwhile, toast pistachios for a few minutes in a hot skillet, then add to a small food processor. Add cardamom, cinnamon, and sugar and pulse a few times until ground. Serve ice cream topped with chopped nuts and dates and a drizzle of date molasses.
Notes
If you prefer chunkier textures, you can stir a few chopped dates into the mixture once smooth; however, dates tend to get hard when frozen, so they may be hard to chew.
For a softer texture, don't freeze for an extended period.
Use full-fat cottage cheese for the best creaminess.
Freeze in a shallow container for faster freezing.
Stir halfway through freezing if not using an ice cream maker.
Let it thaw for 20-30 minutes before scooping, depending on how long it was frozen.
Store in an airtight container in the freezer for up to 3 months.
