Blueberry Crumb Cake is a light yogurt cake full of fruit and topped with almond crumb topping. I made it last summer and it was a huge success. Everybody liked it. This year I absolutely had to make it again.
If you cannot use almonds, you can substitute them with rolled oats. I tried both versions and they both work good. I prefer the one with almonds because it has a nice aroma, but rolled oats are also fine, maybe a little bit more crunchy.
Blueberry Crumb Cake can be served warm or cold together with ice cream as a dessert. It is so full of fruit that it can even be eaten for breakfast.

i am loving the look of this blueberry crumb cake.. definitely need to recreate the recipe!
What is caster sugar? Is it white granulated sugar or powdered sugar? Thanks, Susie in San Antonio
Caster sugar is a fine form of granulated sugar. In the UK granulated sugar has quite large granules so it is not suitable for baking, while in the US granulated sugar tends to be finer. You can use granulated sugar for this recipe.
Looks wonderful! I made a cherry crumble cake a while a go and my cherries all sank. I think using a smaller fruit like blueberries will help, I’ll give it a go! Pinned!
The trick is to dust cherries lightly with flour before putting them into dough. It should prevent sinking.
This is great trick!!!
for the 300g flour – do we use self raising or plain flower
Use plain flower.
can I use sour cream instead of yogurt?
Yes, no problem.
