Blueberry Crumble by Inbar Zuckerberg

You have heard me talking about Inbar in my previous post and I guess she doesn't need any introduction. It is no surprise that I begged her for this recipe. I was on my usual routine on Instagram browsing thru' stories and this popped up. I know I need to give it a try. Come to think of it, begging is an understatement; it should be pestering. Lol!

She emailed me the recipe and the rest is history. To be honest, this is my 2nd try as her recipe is intended for a huge crowd. My 1st attempt ended up a bit too flat. Perhaps I just suck at math but the cake still disappeared within a few hours. Well, I have 2 hungry kids in the apartment, so... I am glad that I decided to double the amount and managed to get it right on the 2nd try.

Quite frankly, I never have any crumble cakes before. Maybe an apple crumbles pie, but this is very new to me and I love it. Especially those corner slices, so cwispy and yummilious. Maybe I should start exploring more crumble cakes adventures; apple, blackberries, figs, peaches, strawberries, etc. The possibilities are endless. I'm excited but in the meantime, let's get started with the recipe.
