Lemon Blueberry Marble Loaf (Gluten-Free, Naturally Sweetened)
This lemon blueberry marble loaf is bright, tender, and swirled with juicy berries, the kind of bake that makes dark mornings feel instantly better.

Honestly, there’s something about this loaf that just makes me happy. Maybe it’s my childhood tie-dye dreams finally coming true. (Tie dye food does seem to be a theme with me. Have you seen my Tri-Color Sweet Potato Stacks or my Tie Dye Potato Waffle Breakfast Stack?)
The swirl of lemon and blueberry here feels like a burst of summer in the middle of cold, dark mornings, and I love how the blueberry adds its signature purple-blue swirl throughout the loaf. (Admittedly, that's why I find ways to slip blueberries into everything from waffles and bagels to cheesecakes and even ice cream).
It’s bright, fresh, and ridiculously moist, the kind of loaf you cut into “just for a slice” and then immediately go back for another.
It lands somewhere between a coffee cake and a quick bread. Light, tender, not overly sweet, and perfect with a hot cup of coffee when winter mornings feel a little extra heavy.
This is one of those bakes that looks special without being fussy. Simple ingredients, a little swirl action, and suddenly the whole kitchen feels happier.
Why this Lemon Blueberry Marble Loaf works
Almond flour keeps the loaf tender and moist, oat flour adds structure, and Greek yogurt brings everything together without heaviness. Swirling crushed frozen blueberries into half the batter gives you that marbled look and pockets of juicy berry in every slice.
If this recipe gets you in the lemon blueberry mood, don't stop yourself from making my Lemon Blueberry Cheesecake Cookies, too. People honestly flip when they take their first bite of them, and then double flip when they hear the cookies are made with almond flour, Greek yogurt, and maple syrup...🤯.

Recipe
Lemon Blueberry Marble Loaf
Ingredients
Method
- Preheat: Heat the oven to 350°F (175°C) and grease and line a loaf pan with parchment paper.
- Whisk: In a large bowl, whisk together 2 eggs, ½ cup Greek yogurt, ¼ cup honey, 1 teaspoon vanilla, lemon zest, and lemon juice until smooth.
- Add: Stir in 1 ½ cups almond flour, 1 ½ cups oat flour, 1 teaspoon baking powder, ½ teaspoon baking soda, and a pinch of salt until just combined. The batter will be thick.
- Divide: Split the batter evenly between two bowls.
- Crush: Add ½ cup frozen blueberries to one bowl and gently crush some with the back of a spoon to release juices and tint the batter.
- Swirl: Alternate scoops of lemon batter and blueberry batter into the prepared loaf pan, then gently swirl with a knife.
- Bake: Bake for 40–50 minutes, until golden on top and a toothpick inserted in the center comes out clean.
- Cool: Let the loaf cool in the pan for 10 minutes, then transfer to a rack to cool completely before slicing.
Notes
- This loaf is lightly sweet and more wholesome in texture due to the almond and oat flour. It is tender and moist, but not fluffy like a traditional wheat flour loaf.
- When measuring the flours, spoon the flour into the measuring cup and level it off. Do not scoop directly from the bag with the measuring cup, as this can unknowingly add extra flour and create a dry loaf.
- Frozen blueberries are actually ideal here because they bleed less into the batter when you swirl.
- The batter should be thick but easily spoonable. If it feels very stiff or dry before baking, stir in 1 to 2 tablespoons of milk to loosen it slightly.
- If the top starts browning too quickly, just loosely tent it with foil while you finish the baking time.
- This loaf slices best once it’s fully cool. I know it’s tempting, but give it a minute.
- If you want more lemon punch, add extra zest. I almost always do.
- Leftovers toast beautifully the next morning.

Let us know how it was!Frequently Asked Questions for the Lemon Blueberry Marble Loaf
You totally can, but frozen blueberries hold their shape better and give a cleaner swirl.
Yes. I like to freeze it whole so that it maintains it moisture! When you pull it out to eat, thaw before cutting.
This loaf is lightly sweet and designed to highlight the fresh lemon and blueberries. It’s very much a breakfast-coffee loaf, but it absolutely holds its own as a light dessert. If you prefer a sweeter result, increase the honey slightly (up to ⅓ cup).
This recipe uses almond and oat flour for a naturally tender crumb and a softer, more delicate texture. I prefer it this way, as I feel it has a cozy, wholesome feel that lets the lemon and blueberries shine.

A few favorites I think you'll really enjoy next.
I'm sorry, but this was not good at all. The combination of the almond flour and oat flour just made it so dry and there was not enough sweetness to it. I was surprised there was not oil or anything in it to give it some moisture. I threw the entire thing out. I'm really disappointed that I spent money on organic lemons, oat flour and wild blueberries.
Ahh, I’m really sorry it didn’t work out for you. That’s especially frustrating when you’ve splurged on great ingredients.
This recipe leans less sweet and relies on the natural moisture from the fruit, but almond and oat flour can be a bit finicky depending on brand and how they’re measured. It definitely shouldn’t come out dry.
If you ever try it again, a splash of oil or a touch more sweetener can easily tweak it to your preference.
This was the best lemon loaf cake I've seen out ther,e with those macro,s definitely make again.
love to hear that Armen, thank you!
Do you recommend allowing the dough to rest for 30 minutes, as I have seen in other bread recipes??? I don't think it can hurt, right? I believe the rest period allows the flours to hydrate and offers a less grainy crumb. Thoughts?
Yes you're 100% right. This recipe doesn't need it... I'm always impatient and want my desserts as quick as possible.
