- 2 large organic eggs at room temperature

How To Make It
- Preheat your oven to 325°F (163°C). Line a standard sized loaf pan with parchment paper and lightly spray with avocado oil.
- In a mixing bowl, whisk together all dry ingredients: flour, corn starch, baking powder, baking soda, cinnamon, nutmeg, and salt. Set aside.
- In another large bowl, beat the eggs and brown monk fruit sweetener until smooth.
- Slowly whisk in the melted butter, then add yogurt, vanilla extract, and warmed almond milk. Mix until well combined.
- Gradually add the dry ingredients into the wet mixture, stirring just until incorporated—do not overmix.
- Pour the batter into your prepared loaf pan and smooth the top.
- Bake for 50 minutes, or until a toothpick inserted in the center comes out clean.
- Allow loaf to cool completely before adding the topping.
- Brush the loaf with melted butter, then sprinkle the cinnamon “sugar” topping evenly over the top and sides. Slice and enjoy!
How Long Are Leftovers Good For?
You can keep your leftover loaf at room temperature, covered for up to 3 days. I refrigerate mine for ultimate freshness. I have not tried freezing this loaf before (it never lasts me long enough). I am not sure how the coating would hold up after freezing.

FAQ’s
Can I use a different sweetener?
Yes! You can sub in coconut sugar for brown monk fruit or stevia for the granulated monk fruit. I don’t recommend liquid sweeteners as they will affect the texture.
Can I use a different flour?
All-purpose gives the best “donut-like” texture, but you can experiment with a 1:1 gluten-free baking flour if needed. Almond or coconut flour won’t work in this recipe.
What’s the best Greek yogurt to use?
Plain nonfat Greek yogurt is best for the macros, but 2% or whole milk versions will also work for richer texture.
Can I make this dairy-free?
You can try dairy-free butter and coconut yogurt or almond-based yogurt, but texture may change slightly.
