Blueberry Crumb Cake

The fruit stalls in the market near where I live have been selling blueberries from Chile recently. Fresh blueberries are hard to come by in Taiwan, so I took the opportunity to stock up a few packs and I keep them in the freezer for future use.

As I was looking for recipes to make use of my blueberries, this blueberry crumb cake recipe caught my eye because of the way the streusel is prepared. I've made cakes with streusel many times before and most recipes call for cold and hard butter. However, for this recipe, butter has to be melted first and so I was curious to see how it will turn out. Preparing the cake batter is rather straightforward and I made some slight changes along the way. I reduced the amount of sugar and I also used plain yogurt instead because sour cream is hard to find in Taiwan. However, the amount of streusel is actually more than what I would normally use for my cake. 1/3 of it is enough to cover the surface of the cake batter and I was contemplating whether I should throw the rest away. But in the end, I decided to use it all and when I had the first bite of the cake, I'm glad that I did! The streusel is very crunchy, almost cookies-like and it definitely complements the moist blueberry cake well.
