Pro Tips & Customizations

  • Want more cinnamon flavor? Add an extra dash to the batter.
  • For extra protein, sub in chocolate collagen or add a spoonful of Greek yogurt.
  • Make it nut-free by using oat flour and avocado oil instead.

Storage Tips

  • Fridge: Store in an airtight container for up to 5 days.
  • Freeze: Freeze slices individually and reheat in the microwave for 20–30 seconds.

Can I use almond flour instead of Fit Flour?

Fit Flour or all-purpose flour works best for structure, but you can use a 1:1 gluten-free blend if needed.

Is this recipe kid-friendly?

Yes! It’s a naturally sweet, soft cake that kids love—especially with the glaze.

How can I make it dairy-free?

Swap the whey-casein protein for a plant-based protein, and use almond milk in the glaze.
