high protein lemon bread highlights
- So moist and fluffy with only one flour (no tapioca, coconut flour, or gluten-free flour replacement here!)
- Made with simple ingredients, plus you can leave out the collagen peptides if you don’t have it.
- Even our gluten-eating friends and family commented on how good it was, having no idea it was gluten-free!
I’m no stranger to big box coffee shops but I’m also no stranger to making healthier versions of what they sell at home. And I don’t mean to toot my own horn, but I’m pretty dang good at it! My Bacon Cottage Cheese Egg Bake (a high protein version of Starbucks bacon gruyere egg bites) has hundreds of raving reviews on the website and Pinterest!
When spring rolls around, I can’t help but stop by Starbucks to get the lemon cake (yes I’m aware it's available all year, but I crave it in the spring) to enjoy with a lavender latte. But, I’ve been eating more and more gluten free and always dairy free and that lemon cake is neither of those, so it was time to make my own version of it.
After a few interactions and the decision to add chia seeds to emulate poppy seeds, I landed on this AMAZING high protein lemon bread. It’s so good that we inhaled it in just one day! Then promptly decided it was coming to Easter brunch with us, where it was also inhaled.
ingredient notes & substitutions
All substitutions are a 1:1 substitute unless otherwise noted. See the recipe card for the full list and quantities.
- The almond flour: there is NO substitute for this.
- The yogurt: Sigis yogurt has a high protein content and is plant based which is why I love it. If you don’t want to use it though or can’t find it, you can use plain Greek yogurt or Olive oil.
- The chia seeds: Chia seeds have 3g of protein per tablespoon so they are a great way to add more natural protein. Feel free to leave these out or swap them for poppy seeds.
- Eggs: I don’t recommend trying to swap out the eggs because they provide rise and moisture to this protein lemon bread.
variations & swaps
- Make it sugar-free: I’ve tested this and had good success with using monk fruit powdered sweetener in place of powdered sugar for the glaze. Pair this with a sugar-free liquid sweetener to use in place of the maple syrup.
- Add a fruit: Try folding in fresh blueberries that have been tossed in almond flour to the batter for a high protein lemon blueberry bread.

a few tips
- Line the pan and grease it! This bread can stick, especially if you try to take it out of the pan before it’s cool. It’s helpful to line it with parchment paper that extends over the edges of the pan so you can lift the loaf out.
- Let the bread cool for at least 15 minutes before attempting to remove from the pan. And let it cool completely before pouring the glaze on and slicing. If you try to slice it before it’s cool, it will crumble.
- To speed up cooling, I pop the cake in the freezer to chill.
- For the glaze, you can add more powdered sugar or lemon juice to achieve the desired thickness. I also recommend letting the glaze set before slicing (the freezer does this quickly!).
- When slicing, use a serrated knife for clean, beautiful slices.
types of almond flour
Almond flour is the base of this bread but it can be purchased in a few different forms. Here's what you need to know,
- Almond flour: This comes as blanched or unblanched and either one is fine for this recipe.
- Super fine almond flour: Again, this is fine for the recipe too but I recommend sifting it to get out any lumps.
- Almond meal: This is made from ground almonds that have not been peeled. For this reason, it's a bit courser and I don't recommend it for this bread.
common questions
Can I make lemon muffins with this recipe?
If you want to make these as muffins, you can bake them for 30-35 minutes or until a toothpick inserted comes out clean.
Is this Starbucks copycat lemon bread healthy?
According to research, almond flour offers more protein than bread flour, maple syrup does not cause your glucose to spike like white sugar, and yogurt offers loads of probiotics to support a healthy gut. So that being said, I would say this bread is pretty healthy.
storage tips
Fridge & Room Temperature: Store the bread in the fridge for up to 6 days. The fridge creates moisture so when the loaf is stored in an airtight container it can get a bit damp over time. I don’t recommend storing the cake at room temperature for more than a day because the cake is so moist it will grow bacteria quickly.
Frozen: The best way to store the lemon bread is in the freezer! I will wrap individual slices in plastic wrap and place them inside a large ziplock bag. They will stay good in the freezer for up to 3 months. When you want to eat a slice, just pop it in the microwave for 20 seconds or leave it on the counter for 15 minutes to soften.
ways to serve this protein lemon loaf cake
- Drinks: Pair the lemon bread with a chaga latte, protein matcha latte, or this lavender vodka lemonade.
- Protein: Sweet and savory are perfect together with this turkey sausage and kale egg bake or this maple chorizo breakfast skillet.
- A dessert spread: Pair this lemon loaf with other healthy desserts like lemon meringue pie, protein carrot cake, and chocolate orange ginger cookies.

Instructions
- Preheat the oven to 350 degrees. Line a bread pan with parchment paper and lightly grease it (just to be sure, ya know?).
- Mix together the 2 cups almond flour, 1 teaspoon baking powder , ½ teaspoon baking soda, ½ teaspoon fine grain sea salt, 4 eggs, ⅔ cup maple syrup, 1 teaspoon vanilla extract, and ⅓ cup collagen peptides until well mixed.
- Fold in the ½ cup Siggi's vanilla plant based yogurt, Zest from 2.5 lemons, and 2 tablespoon chia seeds if using.
- Pour batter into prepared pan and bake for 35-45 minutes, or until a tooth pick inserted comes out clean. Remove from the oven and let cool for 15 minutes before removing from the bread pan. You can speed this up by placing it in the freezer (I wouldn't do the fridge as that can make it gummy from the moist environment). Then remove and place on a wire rack or tray to continue to cool in the freezer quickly or at room temperature overnight.
- While the cake cools, make the glaze by mixing together the Juice from 3 lemons, 1 ¼ cup powdered sugar, Zest from 0.5 lemon, and ¼ cup collagen peptides. It should be a pretty thick glaze so add more powdered sugar as needed.
- Top the cooled bread with the glaze and let it chill or set until the glaze has hardened. Again, the freezer is a great way to speed this up. Then slice and serve!
