🛒 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 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.

⏰ 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.
