To make the Oreo cookie crust, stir together all the ingredients and press into a high-sided 9” springform pan lined with a round of baking parchment. This is best done with the bottom of a measuring cup. You want to get the crust nice and compacted, covering the bottom of the pan in an even layer.
Pre-heat the oven to 325F and place a large baking dish of water in the bottom of the oven to heat up also.
Using a stand mixer with the beater attachment or an electric hand mixture, beat together the cream cheese, sugar and vanilla, until smooth and creamy. Then scrape down the sides and beat in the cocoa powder.
Scraping down the sides again, add 1 tbsp of the red food coloring, and beat to combine. The shade of red given will depend on your brand; add the remaining 1 tbsp 1/2 tbsp at a time until you achieve the desired color batter, which is true to shade when baked.
Scrape down the sides, and beat in the heavy cream until only just combined. Do the same with the eggs, one at a time, scraping down the sides between each egg. Switch to a spatula after the last egg to make sure the mixture is combined, adding a pinch of kosher salt. Over-beating the mixture will lead to a cracked cheesecake!
Scrape the mixture into the prepared pan, smoothing the top the best you can. Bake in the middle of the oven above the water bath for 1 hour 15 minutes. Don’t open the oven, which can also cause the cheesecake to crack!
Crack the oven door and allow the cheesecake to cool for 45 minutes in the oven before transferring it to the refrigerator to chill for at least 4 hours, or overnight.
