Preheat and Prep: Preheat your oven to 350°F (175°C). Line a mini muffin tin with paper liners or grease well.
Mix Dry Ingredients: In a bowl, whisk together the flour, cocoa powder, baking soda, and salt. Set aside.
Cream Butter and Sugar: In a separate large bowl, beat the butter and sugar until light and fluffy. Add the egg, vanilla extract, and red food coloring, and mix until combined.
Combine Wet and Dry: Gradually add the dry ingredients to the butter mixture, alternating with buttermilk. Mix until just combined.
Make Cheesecake Filling: In another bowl, beat the cream cheese, sugar, egg, and vanilla extract until smooth.
Assemble Bites: Spoon a small amount of red velvet batter into each muffin cup, filling about halfway. Add a dollop of cheesecake mixture on top.
Bake and Cool: Bake for 15-18 minutes or until the edges are set and the cheesecake topping is slightly firm. Let cool completely before serving.
