Despite using only 1/3 cup sugar instead of 1/2 cup as per the recipe, I found the cupcake too sweet, even without the DDL!
You can use any extract, vanilla or otherwise for your favorite flavor.
I was intending to keep an Oreo and the bottom of the muffin and bake the cheesecake, but my B who was supposed to buy it along with the cheese, conveniently forgot it, so I skipped it! :)
