the peanut butter cup one got stuck in my mind (who'da thunk it?), but I'm more a fan of dark chocolate with peanut butter, so I already knew I wanted to change the topping a bit. Then, when my search for chocolate wafer cookies for the crust without "creme" in the middle started to turn into a long one, the pretzel idea formed. Et Voila!
1 1/2 c mini pretzel twists
2 Tbsp melted butter
2 Tbsp brown sugar
1 Tbsp butter for pan
Crush pretzel twists into tiny pieces in a plastic zip-top bag or in a food processor. Add melted butter and brown sugar and mix well.
Butter a 7" cheesecake or springform pan and press pretzel mix into bottom and part way up the sides. Put pan in fridge until batter is ready.
Bring all ingredients to room temp before mixing, either by leaving on the counter for 1-2 hours or placing in a bowl of lukewarm water for 10 min.
12 oz cream cheese
1/2 c sugar, granulated or raw
1/2 c peanut butter
2 Tbsp sour cream
1 Tbsp all-purpose or cake flour
One at a time, add eggs, mixing on medium high about 30 seconds and then scraping down the sides between the first and second additions. Mix another 30 seconds after adding the second egg, then scrape down sides of bowl and mix just 5-10 more seconds (overmixing can make for a yucky cheesecake!)
Place 2 cups water in the liner of the Instant Pot pressure cooker. Insert the trivet and place the pan on top of the trivet. If you're using a springform, make a foil sling to help pull out the pan when it's done. If you're using a Fat Daddio cheesecake pan, you can pull it out with the trivet handles.
If the middle is set, you're good! Run a knife around the edge of the pan to help the cheesecake loosen later. Let cool 1 hour at room temp before making the topping.
3.5 oz dark chocolate, ideally 60-70% cocoa
1/3 c heavy cream
a little flaky sea salt (optional, but Maldon if you can find it)
ten or so more pretzels
Use a serrated knife to finely chop the chocolate. Place it in a heatproof bowl. Bring the cream just to a boil (careful: this can happen very quickly with such a small amount!) and then pour it over the chocolate. Immediately start whisking together; whisk until smooth.
Pour over cheesecake and put cake in refrigerator for at least one more hour, preferably two to six.
Just before serving, decorate with more pretzels and sprinkle with a little flaky sea salt.
Prepare to melt a little inside from the yumminess.
