Skin and chop peach into cubes, discarding the skin.
In a medium bowl, add 8 oz room temperature cream cheese, ¼ cup brown sugar, ⅛ cup greek yogurt, ¼ tsp cinnamon and mix together until creamy and smooth.
Add 1 Tbsp flour, 1 Tbsp bourbon, and 1 egg to the mixture and mix until well incorporated.
Layer ¼ of the cheesecake mixture into each of the two mini springform pans. Smooth out to an even layer. Then sprinkle chopped peaches, and ¼ of the crumble mixture evenly over each of the pans. Reserve remaining crumble for topping the cheesecakes later, as well as any leftover peach cubes.
Divide the remaining cheesecake mixture across the two pans, smoothing out the mixture on top. I also recommend banging each pan gently on the counter to remove any air bubbles.
Bake at 350°F for 15 minutes, then remove the pans and turn oven temperature down to 300°F. Divide the remaining crumble mixture and top each cheesecake with the mixture at the 15 minute mark.
Bake cheesecakes another 10 minutes or until center is only slightly jiggly (it will firm up while cooling). Top with any remaining peaches
