“Grandma Gerdi’s Apple Crumble Sheet Cake” is one of my favorite apple cakes! I have hardly changed her simple recipe in the last 25 years, because it will get you a perfectly delicious, juicy apple cake with a crunchy crumble topping that is a real classic! The
most important when baking apple pie is the right apple variety, I prefer to use tart apples like Red Boskoop
Or Cox´s Orange for my cakes and pies. These apples are fruity and a little sour and make the perfect choice for baking. Don´t worry if you have trouble finding exactly the above-mentioned varieties. “All roads lead to Rome” and you can certainly use other apples for this delicious apple cake.
Easy German Apple Crumble

For this recipe, I always use my homemade vanilla sugar with real vanilla and add some cinnamon sugar and calvados to the apples, that are grated with their skin. By using the apple with the skin, the cake gets a more intense flavor and it will save you a lot of time, that you would otherwise spend peeling them. This delicious apple crumble sheet cake is very easy and quickly baked with my step by step recipe.
My favorite time to bake this tasty sheet cake is during the cold season. Freshly baked and still warm, it will make even the coldest days feel cozy. Needless to say, this timeless cake is just as suitable for any other time of the year. I can hardly remember how many times I’ve baked this all-time favorite for birthday parties or school events. This classic apple cake is perfect if you’re expecting a bit more visitors or have promised to bring something for a party.
Easy Recipe Apple Crumble Sheet Cake




We love “Grandma Gerdi’s German Apple Crumble Cake” with some whipped cream, vanilla sauce or a scoop of vanilla ice cream! It tastes simply delicious, whether warm from the oven or cold from your hand. A crumble sheet cake with apples is a simple, quick and uncomplicated classic cake for every day and thanks to the delicious combination of the fruity apple center and our German crumbles (“Streusel”) on top, this traditional German apple cake remains soft and moist even the next day and th
e day after. If you also want to try your hand at this wonderful cake, I recommend baking it with butter only. I bake all my cakes and pies with butter and find that it has a huge advantage over margarine in terms of flavor. Also I use very fine sugar for this cake, as it dissolves very well and quickly when stirred into the butter. If you have any questions about the recipe or want to give me a feedback because you’ve already tried it, I appreciate your comment. I’ll do my best to answer your questions quickly!

I hope you enjoy reading, strolling through and trying out my cooking and baking recipes! Grandma Gerdi´s apple crumble sheet cake is one of my favorite cakes.
