Recipe Notes

  • If too much frosting or piled high style frosting is not desired, half a batch would be enough.
  • The blueberry sauce recipe is made to be more than enough sauce for drizzling the cupcakes. If not too much blueberry sauce is desired, half of the batch listed would be enough.
  • Making the full batch is okay, and leftover can be used for pancakes, smoothies, drizzled over favorite Greek yogurt, or just eaten on its own as it is basically just pureed blueberries.
