- Note: Before you begin, make sure the cream cheese, sour cream, and eggs are at room temperature. 
- Preheat the oven to 325°F and line 2 cupcake tins with liners or spray a mini cheesecake pan with nonstick spray. (This recipe makes 18 cheesecake bites so you only need to line 18 cups.) 
- Blitz the Oreos in a food processor until you have fine crumbs. - 18 oreos 
- Add in the butter and blend again until the Oreo crumbs are moistened. - 4 tbsp. melted butter 
- Press the crumbs into the prepared cupcake tin, ~1 ½ tsp. Press down using a spoon or even a clean lid from a milk container. 
- Bake for 5 minutes. Remove from oven and set aside to cool. 
- Beat the cream cheese for 2-3 minutes in a stand mixer fitted with the paddle attachment, scrape down the sides of the bowl as needed. - 16 oz. cream cheese 
- Add the sugar, peanut butter, sour cream, flour (or cornstarch), vanilla, and salt and mix again. - ½ cup granulated sugar, ½ cup creamy peanut butter, ⅓ cup full-fat sour cream, 1 Tbsp. flour or cornstarch, 1 tsp. vanilla extract, pinch of salt 
- Add the eggs 1 at a time on low speed, mixing just until the yolk disappears. Do not over-mix. - 2 eggs 
- Fill each cupcake tin with the filling over the prebaked Oreo crust. 
- Bake for ~16-18 minutes or until they have a slight jiggle in the center. 
- Remove from the oven and cool completely. Refrigerate for 4 hours at least, or overnight. 
- Make the ganache: add the chocolate chips, butter, and corn syrup in a microwave-safe bowl and melt in intervals so it melts evenly, stirring in between I like to do 30 second increments. Then, stir in vanilla. - 1 cup dark chocolate chips, ¼ cup salted butter, 1 Tbsp. light corn syrup, ½ tsp. vanilla 
- Spoon ganache on top of the chilled cheesecakes. 
- Top with a mini reeses candy that’s cut in half. - mini peanut butter cups 
- Chill again until the ganache is set, sprinkle with flaky sea salt if using, then enjoy! - maldon flaky sea salt
