If you can’t buy these on the Hogwarts Express, you can make them yourself!
Cauldron Cakes by Christina
Coat about 18 2.5" muffin cups with nonstick cooking spray and set aside.
In a bowl, combine the flours (all-purpose and wheat), sugars (granulated and brown), cocoa powder, baking soda, and salt.
In another bowl, combine milk, applesauce, oil, molasses, balsamic vinegar, and vanilla. When combined, add to flour mixture.
Stir just until moistened (batter should be lumpy).
Stir in half of the chocolate pieces.
Spoon the batter into prepared muffin cups, filling each one just over half-full. Sprinkle with remaining chocolate pieces.
Once muffins are fully cooled, take a knife and cut a circle through the middle of the muffin to make a hole for the cotton candy to be inserted. You should now have a cylindrical muffin piece cut out. Next, cut this cylindrical piece in half and insert it back into muffin to create a bottom. The muffin should have a small cavity, but not be bottomless.
Pinch off a large piece of cotton candy to fill the cavity of the muffin. Enjoy!
