These Valentine's Day cheesecake bars have a red velvet cookie crust and a white cheesecake layer on top. They are easy to make, but it is important to allow the cream cheese to come to room temperature before mixing. The recipe calls for all-purpose flour, cocoa powder, baking soda, salt, butter, sugars, eggs, vanilla extract, red liquid food coloring, cream cheese, and sour cream. The bars are baked in the oven for 42-45 minutes and need to be refrigerated for at least 2 hours before serving. The bars can be stored in the fridge for up to 3 days or frozen for later consumption.
