A Blueberry Crumble is similar to Blueberry Cobbler. A Blueberry Cobbler is topped with dollops of batter or biscuit dough while a Blueberry Crumble is topped with streusel crumb topping.

  1. I just made this blueberry crumble, and it was amazing. I followed the recipe exactly as written, do Please do NOT substitute butter ! Listen to Joanie, she has perfected these one dish servings.
    It was perfectly balanced, not to sweet , right amount of crumbs to berries and delicious crispy top. By the way I just purchased the mini Breville oven for my 16 year old daughter . And that is what I used to bake this in, came out great. Next is the oatmeal cookies.
