Lavender Cake Recipe Tips and FAQ

How to get the perfect lavender flavor.

If you happen to love culinary lavender, one drop is probably fine in this recipe. However, most people who’ve tried this recipe think a full drop is a dash too much. It’s almost impossible to do 1/2 a drop, so the answer is to double the ingredients.

For the perfect balance of flavor, make two mug cakes with the one drop of lavender. Share with a friend, or cover half and store in the refrigerator for the next day.
