A few things to note:

  • This recipe makes 6 cupcakes, instead of the standard 12. If you wish to make a whole dozen, simply double your ingredients. Baking time remains the same.
  • Be sure your butter is softened before using. This will give your cupcakes a much softer texture. How to Soften Butter
  • Also, don’t over mix your batter. Mix it just to combine. Again, this will keep your cupcakes from becoming too dense.

Delicious recipe and easy to follow. I only got 10 small muffins ( mini muffins).

Can I use cake flour instead of flour and get same result?

Hi Tamara- I'm sure the cake flour will work, but, I can't say for certain..I've only used AP flour for these. Please let me know if you do use it and how it works out!
