Tips & Tricks

These  bundt-shaped cakes are delicious as they are, but feel free to add a lemon-flavored glazing or you could even add a sprinkle of your favorite powdered sweetener.

If by any chance you need to store these, place them in air-tight containers and keep in the fridge for up to 4 days.
