Top with homemade whipped cream and sprinkle with additional finely chopped pistachios.
Serve/enjoy!
Rather than finely chopping them myself, I put more than I would need through my food processor, use what I need, then store the rest in a sealed container for future use. I really recommend having the extra pistachios on top of the whipped cream, it add that extra punch of pistachios while adding a little distinct saltiness to balance out the lightly sweetened whipped cream.
*Electric Pressure Cooker trial notes: I placed one of these mini cheesecakes, skipping the toasting crust step, into my Instant Pot (on trivet) with about 1.5 cups of water. I cooked on high pressure for 12 minutes, and natural release for 15 minutes (then release remaining pressure). I then continued with remainder of directions.
