Add graham crackers to a food processor until you get about 1 1/2 cups of crumbs. Add in the melted butter and cinnamon and pulse until combined.

Pour into the bottom of a greased 7" springform pan and use your hand or the back of a spoon to press and form a crust bringing the crumbs up about 1 inch on the sides.

Place the crust in the freezer while you make the filling.

In the bowl of a stand mixer (or use a hand mixer) with a paddle attachment, cream the cream cheese for 3-4 minutes or until completely smooth and there are no lumps.

Slowly pour in the sugar and flour and mix until just combined.

Add vanilla and heavy cream and mix on low speed until combined. Slowly increase the speed to high for about 1 minute,

Scrape the sides and bottom of the bowl and make sure there are no lumps. Give one final mix before adding the eggs.

Add the eggs one at a time and mix just until the yolk disappears into the batter.

Prepare the crumble by adding the brown sugar, cinnamon, and flour into a medium bowl and whisk to combine. Pour in the melted butter and use a fork to mix until a crumble forms.

Pour 1/3 of the filling into the prepared crust then top with about 1/3 of the cinnamon crumble and continue two more times and top the cheesecake with the remaining crumble. Gently tap the bottom of the pan on the counter to release any air bubbles.

Cover the pan completely with aluminum foil. Add one cup of water into the inner pot of your Instant Pot and add in the trivet,

Place the cheesecake on top of the trivet and set your pot to high pressure for 40 minutes and allow to naturally release.

Once you can open the pot, remove the cheesecake and allow to cool to room temperature on a wire rack.

Place the cheesecake in the refrigerator to set for at least 6 hours but overnight is recommended.

Add the cream cheese and butte into the bowl of a stand mixer and whisk until light and fluffy, about 2-3 minutes. Add in powdered sugar and vanilla and mix until smooth.

Add the crema cheese frosting into a piping bag fitted with a large star tip, and pipe a generous amount around the sides of the cheesecake.

Store in an air tight container in the refrigerator for up to three days.
