🛒 Ingredients
Ready to try a gluten-free blueberry buckle? Gather your ingredients and let's get started.
- eggs: at room temperature
- sweetener: granulated sugar or Monkfruit sweetener
- almond flour: finely ground
- gluten-free flour blend: I use Bob's Red Mill Gluten-free 1 to 1 Baking Flour
- baking powder: gluten-free, if necessary
- lemon zest
- salt: Kosher salt or sea salt
- pure almond extract
- olive oil: or melted butter
- blueberries: fresh or frozen (don't thaw them first)
- streusel topping: almond flour, coconut sugar (or brown sugar), butter, cinnamon
🥄 Instructions
- Line an 8-inch square baking pan both ways with strips of parchment paper.
- Combine the streusel ingredients in a small bowl, using your fingers to work the butter into the sugar and almond flour. Set aside.
- In a medium bowl, whisk the dry ingredients together: the almond flour, gluten-free flour blend, baking powder, lemon zest and salt.
- In a blender, food processor or using a mixer, blend the eggs, sweetener, almond extract and olive oil.
- Toss the blueberries with the dry ingredients. Coating them with flour helps to prevent them from sinking to the bottom of the cake.
- Add the wet ingredients to the dry ingredients, stirring just until blended.
- Transfer the batter to a prepared pan and sprinkle with the streusel topping. Bake!
👍🏼 Helpful baking tips
A note about sweeteners: I've made this recipe with both granulated sugar and with Monkfruit sweetener with erythritol. If you use Monkfruit, decrease the baking time a little so the cake doesn't end up being too dry. The one in the photo was made with Monkfruit.
Sugar provides more than just sweetness to cakes. It helps baked goods retain moisture for longer. While it's tempting to reduce the amount of sugar in a recipe (as we often want to reduce calories) it enhances the flavour of other ingredients, keeps cakes and muffins moist, and it helps to trap air, making your baking light and tender.
Baking times: This blueberry buckle may take anywhere from 33 to 40 minutes to bake in an 8-inch square baking pan. If you use a glass baking pan, it will absorb heat quickly and bake evenly. A cake baked in a dark metal pan will take less time than one baked in a shiny pan.
Temperature: always check your oven temperature with an oven thermometer as ovens can vary by 25°F. or more.
❓ Reader's Questions
To make a traditional buckle cake, you either top the cake batter with fruit or stir it into the batter. As it cooks, the batter rises, or buckles around the fruit.
A coffee cake is similar to a buckle. It's any cake, usually with a streusel topping designed to be served with coffee or a hot drink. It may or may not have fruit.
You can use frozen blueberries in this coffee cake recipe, but don't thaw them first. Fold them in gently to avoid having a purple cake!
⏰ How to store coffee cake
This blueberry buckle, blueberry coffee cake--whatever you'd like to call it--is amazing when served warm from the oven! Let it cool for about 10 minutes, then slice and enjoy.
To store: store at room temperature in a covered container for 2 - 3 days. For longer storage, I'd suggest refrigerating it.
To freeze: Store in an airtight container and freeze for up to 3 months. You can also cut pieces, wrap them individually in plastic wrap, pack into an airtight container and freeze.

Hi Elaine !!!!
I hope you see my message 🙂
I would like to do this cake that looks so so good.
My husband loves blueberry 🙂
Is there a way I can make this cake, looking like yours 🙂 Or it is not preferable.
If yes, can you help me with what I should use that I have on hand, Almond flour, normal flour or potatoes flour and how much.
I don't have xanthan gum too.
And would it be good if I use avocado oil instead of olive oil ?
Thanks to you and have a beautiful day.

Hi Karine, Happy to hear you'd like to make this cake! This recipe was tested with a combination of almond flour and a gluten-free flour blend that contains xanthan gum (a necessary ingredient.) When you say "normal flour" I presume you mean all-purpose wheat flour. If you don't need this cake to be gluten-free, you can substitute the same amount of all-purpose flour for the gluten-free flour blend. While I haven't tested it and can't guarantee results, it should work. You can also substitute avocado oil for the olive oil. Thanks for your question!
Karine
Ohhhh Elaine that is so much appreciated that you answer my question 😉 Thank you so much ! I am trying to not have gluten but it seems to not matter despite having health issue,
Another last question 🙂
I was looking at your other recipe and one seems really similar to this one and I have all the ingredient this time. It is the One-Bowl Flourless Lemon Almond Cake. If I put inside 1/2 of fresh blueberry, would it be find ? Will the inside cake look and taste a little like the other one ? Will be easy in that case 😛
Sorry my question 🙂 and a little Hi from Quebec 🙂
I also plan to do your seafood chowder that looks really good 🙂 🙂
Elaine
Hi again Karine, Yes--that one-bowl flourless lemon almond cake is delicious and I think you could add 1/2 cup of blueberries to it quite successfully! Add the berries after you've mixed all the batter and stir them in gently so you don't end up with a purple cake! Good luck and let me know how it turns out! --And yes, that seafood chowder is lovely!
Jen
This turned out perfectly! I froze individual squares in plastic wrap and put them in a container for snacks for later.
Laura
Perfect for upcoming blueberry season! Will this freeze?
Elaine
Yes! Store it in an airtight container and it will last for up to 3 months.
