You can make this with any fruit really, even if posted with blueberries. I have made this with apples, caned pinapple, peaches, strawberries and it even works with perservatives or jam. Berry Bake - my favorite cake! Note: I have done corrections after the revviews, cut down on batter, changed everything into cups and changed the name of the recipe as it indeed is crumbly. Please do have cream or/and icecream with it and enjoy it as it is.
