Summer is calling, school is out and picnics outside in the garden, on the porch or at the beach are the perfect setting for get-togethers with family and friends.
A German Apple Crumb Cake makes for a delicious dessert. You can enjoy it after a nice meal or with a cup of coffee for a typical afternoon -“Kaffeklatsch” (German afternoon coffee time with friends; also “Kaffeekränzchen”). The cakes slight tartness with crunchy crumbles on top makes it feel light and not heavy.
Apfel-Streuselkuchen was always one of my favorite cakes my aunt had made for us. And even though the recipe calls for apples in the original recipe, we have tried it with pears or peaches. In fact the photographs here are from a cake we have made with both, apples and peaches.
Side note: The cake is best when made and consumed on the same day. The crumbles are nice and crunchy that way. When kept over night or in the fridge for a few days, I recommend to put the cake in the oven for a short while to warm it up and give back some crunchiness to the crumbles.
