Paleo
Gluten Free
This Blueberry Buckle Coffee Cake recipe makes a delicious low sugar, gluten free, and paleo-friendly treat! This lighter take on a classic dessert features fluffy almond flour cake studded with fresh blueberries and a cinnamon sugar crumb topping! Serve this cake at your next brunch; nobody will notice that it’s a healthier dessert because it tastes like the real deal!
Egg free and dairy free option included!
Ya’ll, we’re half way through the year and I’ve already made 10 gluten free dessert recipes! Most with some sort of fruit topping and cake-like texture. And yet, here I am again making another. Naming this berry dessert was probably the hardest part. That’s a good thing, right? Because really, naming fruit desserts boggles my mind, ya’ll; there are just too many names for the same thing! I have memories of a similar problem naming my recipe for vegan hot fruit bake. To be honest, I’m indecisive about this one and I need your help.
The recipe is probably for a blueberry buckle, almost definitely for crumb cake, which also means it’s coffee cake! Oh, and technically, I think it may even fall into the category of a fruit crumble!
INFORMATION. OVERLOAD.
Allow me to explain and then you can decide for yourself what this dessert really is, mmmk? Actually, allow the Farmer’s Almanac to explain, because their article on the topic is very helpful.
What’s the difference between buckle, crumb cake, and coffee cake?
Blueberry Buckle
By definition, a buckle dessert is fluffy cake with fresh fruit throughout (almost always blueberries) and a streusel topping. The name, blueberry buckle, is appropriate because as it bakes, the cake buckles under the weight of the fruit.
Fluffy cake – CHECK. We have almond flour cake, with a tiny bit of coconut flour to help add structure and moisture.
Fresh blueberries – CHECK. If you don’t have fresh berries, you can use frozen.
Streusel topping – CHECK. Streusel is a crumbly topping made with fat (butter), flour, sugar, and cinnamon.
Crumb Cake / Coffee Cake
Crumb cake is simply one type of coffee cake. So, this one is easy. It’s not one name or the other; it’s both.
Here’s where it can be a little confusing. The definition of a coffee cake is almost exactly what a buckle is, with one difference. Coffee cakes usually (but not always) have a ribbon of cinnamon running through them.
Fruit Crumble
Crumbles are baked fruit desserts covered with streusel topping. It’s important to note that crumble topping does not have oats in it, and neither does the topping of my blueberry buckle.
For the record, a fruit dessert that has streusel topping made with oats is known as a crisp. They’re usually gluten free as well; like this coconut summer berry crisp.
7 simple ingredients you need to make this grain free blueberry cake-like dessert!
- Blueberries (fresh or frozen)
- Grain Free Flours (Almond flour and coconut flour)
- Baking Powder
- Unrefined sugar
- Butter or coconut oil
- Egg (or Flax egg)
- Non Dairy milk
Cinnamon is optional, but oh so heavenly!
P.S. this blueberry cake pairs quite nicely with whipped coconut frosting/cream or yogurt. Just sayin…

Pin RecipeDescription
This blueberry buckle is a fluffy almond flour coffee cake studded with fresh blueberries. The streusel topping gives the cake just a little bit of sweet crunch. It’s perfect for brunch or dessert. Low sugar, low carb, gluten free, and paleo-friendly.
Ingredients
- 1 1/4 c blanched almond flour
- 4 tbsp coconut flour
- 2 tsp baking powder
- 1/4 tsp salt (kosher salt)
- 1/2 c sugar-free substitute or 2/3 coconut or raw sugar (baking stevia, monk fruit, or works great or xylitol) – See notes
- 1/4 c softened butter or naturally refined coconut oil
- 2 whole eggs at room temp (vegan option: Flaxseed egg 1 tbsp + 2.5 tbsp water) – see notes for egg and vegan egg baking tips
- 3–5 ounces almond milk (as needed)
- pinch of cinnamon
- 1 1/2 c blueberries
Topping
- 2 –3 tbsp butter or oil, chilled and sliced
- 1/3 c almond flour
- 2 tbsp sugar free substitute or coconut sugar (See notes for other sugar free options.)
- 2 tsp cinnamon (optional)
- extra berries
Instructions
- Preheat oven to 350F. Line an 8×8 brownie/baking pan with parchment paper or grease well with non-stick cooking spray. Set aside.
- Sift your almond flour, coconut flour, baking powder, and salt together into a bowl.
- Beat 1/4 cup butter (or oil), sugar, and eggs with an electric mixer or stand mixer in a large bowl until smooth. Next, gently pour in the milk (start with 3 ounces) and mix/beat again until fluffy.
- Add the almond/coconut flour mixture to the wet ingredients and stir again. Note – When using coconut flour, the batter will be more course and/or thick. If it’s too thick, add 1-2 more ounces of milk and mix again.
- Finally, fold in the blueberries and spread batter into prepared pan. I like to sprinkle a little cinnamon on top of the batter or mix with blueberries before adding to the batter. This is optional.
- Set pan aside while you make the topping.
- Mix coconut sugar (or raw sugar), 1/3 cup almond flour, cinnamon, and chilled butter (or solid coconut oil) in a bowl and crumble with hands. Spread this on top of batter, then lightly press topping into batter using fingertips.
- Bake in preheated oven until golden on the edges and a toothpick inserted in the middle comes out clean, about 35 minutes. For best results, cover with foil the last 5-10 minutes to prevent burning more than desired. Let cool or place in fridge to chill before slicing.
Notes
- Sugar free sugar substitutes – Baking Stevia, Monk Fruit Sweetener, or Xylitol. Just reduce to 1/2 c for main batter. You may use raw sugar, coconut sugar, or brown sugar for this cake, however the sugar content will be higher than what the nutrition label says below (per slice).
- Egg free option/Vegan option – Replace egg with flax egg. Prepare your flax egg by combining your ground flaxseed with water. Allow to sit for 10-15 minutes until a gel/egg-like texture forms. Fold this in with your batter when combining wet/dry ingredients. Baking times will vary. Check at 25-30 minutes for doneness. Let cool and then sit in fridge to set for 10 minutes before slicing.
- For a softer crumble like cake use only one egg, versus two. It will be very soft when slicing, so best to wait and slice once cooled or chilled a bit in the fridge. Equally delicious!

Oh I am so glad! Isn’t it like a cloud of cakey goodness? Haha! Keep me posted on if you try other recipes. <3
I followed this recipe (used rice milk instead of almond milk) as directed and was disappointed with the result. The buckle was too wet with almost a mushy consistency even after thoroughly baking it. Perhaps the 4-6 ounces of non dairy milk is too much in this recipe? I won’t be making this one again.
★
Hmm that’s odd. That’s shouldnt have happened. Did you chill it after? So sorryx I’m happy to retest with rice milk.
I have calculated this at least 6 different ways including counting the carbs in every ingredient and i get far less carbs per serving. I used real eggs, swerve sweetener and everything else was the same. Am i counting it incorrectly? Your calculations are much higher. Help!!
★★★★★
Also, it was sooo good. I even dropped dollops of ”cheesecake” on top before baking. And I added almond extract to the batter.
★★★★★
I used raw sugar, that’s probably why. But glad yours is lower! And that you liked it. hehe. 😉
The recipe looks great! Have you ever made it the night before? Like, chill it in the fridge and baked it the next morning? I think I’ll try that but wanted to check that out.
I think that would work! I haven’t tried it but keep me posted.
Is our new family favorite

Hi there! I haven’t made this recipe yet, but I was wondering what kind of oil would work best for the topping; would coconut oil be ok, rather than butter as I am paleo?
SUre! I would try naturally refined coconut oil so it doesn’t taste like coconut and has higher heat index
Looks amazing! One question – if using frozen wild blueberries, should I defrost them first before mixing into the batter? Thanks!
★★★★★
I would keep them frozens so they don’t bleed out. KEep me posted!
I had some blueberries I needed to use up so I tried this recipe. I don’t follow a Paleo diet, but I do bake a lot with Almond flour. So I made changes – used gluten free flour instead of coconut flour; use granulated sugar instead of sugar substitute, and used brown sugar for the topping instead of sugar substitute. It came out great! Soft and yummy. Next time I think I will add a 1/2 tsp of Almond extract to bring out the almond flavor more. Thanks much!
