Preheat your oven to 325°F (163°C). Lightly grease your 9-inch springform pan or line the bottom with parchment paper.
In a large mixing bowl, beat the softened cream cheese and granulated sugar together using an electric mixer on medium speed until smooth and creamy with no lumps.
Add the sour cream, eggs one at a time, and vanilla extract to the cream cheese mixture. Beat on low speed just until fully incorporated.
In a separate bowl, whisk together the all-purpose flour, baking powder, salt, and ground cinnamon. Gradually add this to the wet ingredients, folding gently with a spatula until just combined.
Pour the batter into your prepared springform pan and smooth the top. Bake in your preheated oven for 50-60 minutes, or until the center is set but still slightly jiggly and the edges are lightly golden.
Allow the cheesecake to cool in the pan on a cooling rack for about an hour. Meanwhile, mix melted butter, powdered sugar, and milk to create a simple glaze. Drizzle this glaze over the slightly warm cheesecake.
If using turkey bacon, sprinkle the cooked and chopped pieces evenly over the glaze once it has set for a savory contrast.
