The Best Streuselkuchen Recipe – A German Crumb Cake is my go to answer for those days when you want something cozy but you do not want to babysit a fussy dessert. You know the feeling, you want cake with your coffee, but you also want it to be easy, forgiving, and satisfying. This one checks all the boxes with a soft base and that thick, buttery crumb on top that somehow makes everything feel like a small celebration. I started making it after tasting a neighbor’s German baking, and I have been slightly obsessed ever since. If you have ever felt intimidated by German cakes, this is the friendly one to start with. 
Ingredient notes and substitutions
This is the part where I save you from an extra grocery run. Streuselkuchen is pretty flexible, and you can still get a lovely result even if you swap a few things. Here is what matters most and what you can play with.
Flour: I use all purpose flour, and it works great. If you are curious about flour choices for baking in general, I liked this deep dive on what is the best flour for French bread because it explains how different flours behave, and that knowledge carries over to cakes too.
Butter: Real butter gives the crumbs their rich, classic flavor. If you only have salted butter, just reduce the added salt a bit. I do not recommend margarine here because the crumb texture can turn a little weird and greasy.
Sugar: Regular white sugar is totally fine. For a slightly deeper taste, you can swap part of the sugar in the crumbs with light brown sugar.
Milk: Whole milk makes a softer cake, but any milk works. Even oat milk works in a pinch, though the flavor will be a touch less creamy.
Yeast or not: Some traditional Streuselkuchen uses yeast dough. My version uses baking powder for an easier, quicker bake. It still gives you that classic crumb cake feel without waiting around for dough to rise.
Spices: Cinnamon in the crumbs is optional, but I always add it because it makes the kitchen smell amazing.
One more thing. If you are in a German baking mood and want more ideas after this cake, this collection of German recipes is a fun rabbit hole to go down.
Recipe Tips
I have made this cake enough times to know exactly where things can go sideways, so let me help you skip the frustration. These tips are simple, but they matter.
Tip 1: Keep the crumb topping chunky. When you mix the streusel, stop when you have pea sized and almond sized clumps. If you overmix, it turns into a paste and bakes up like a flat layer instead of crumbs.
Tip 2: Do not pack the flour. If you scoop flour straight from the bag and pack it down, your cake can turn dense. Spoon it into your measuring cup and level it off.
Tip 3: Line your pan if you want tidy slices. A simple parchment sling makes it easy to lift the cake out and cut clean squares.
Tip 4: Watch the edges. If the crumbs start getting too dark but the center needs more time, loosely tent with foil for the last few minutes.
Tip 5: Let it cool before cutting. Warm Streuselkuchen is tempting, I get it. But if you cut too soon, the base can crumble and the topping may slide a little.
I made this for Sunday coffee and it disappeared before lunch. The crumb topping was perfect and the cake stayed soft even the next day. This is a keeper.
How to Make Streuselkuchen Step by Step Instructions
Okay, here is the exact way I do it at home. This is written for a standard 9 inch square pan or a similar sized baking dish. You can double it for a 9 by 13 if you are feeding a crowd.
What you will need:
- 2 cups all purpose flour, divided
- 3 quarters cup sugar, divided
- 2 and 1 half teaspoons baking powder
- 1 quarter teaspoon salt
- 1 teaspoon vanilla extract
- 2 large eggs
- 3 quarters cup milk
- 1 and 1 quarter sticks butter, melted and slightly cooled (about 10 tablespoons)
- Optional: 1 to 2 teaspoons cinnamon for the crumb topping
Step 1: Heat the oven and prep the pan.
Set your oven to 350 F. Grease your pan, or line it with parchment if you want easy lifting later.
Step 2: Make the streusel topping first.
In a bowl, stir together 1 cup flour, about 1 half cup sugar, the salt, and cinnamon if using. Pour in about 6 tablespoons melted butter and mix with a fork until you get chunky crumbs. If it looks too dry, add a teaspoon more butter. If it looks too wet, sprinkle in a spoonful of flour. Set it aside.
Step 3: Mix the cake batter.
In another bowl, whisk together the remaining 1 cup flour, the baking powder, and the remaining sugar. In a separate bowl, whisk eggs, milk, vanilla, and the remaining melted butter. Pour the wet into the dry and stir just until you do not see dry flour. Do not overmix.
Step 4: Assemble.
Spread the batter in the pan. It will be fairly thick. Sprinkle the streusel evenly over the top, using your fingers to break up any huge clumps and also keep plenty of medium clumps.
Step 5: Bake.
Bake for 30 to 40 minutes, depending on your pan and oven. It is done when the top is golden and a toothpick comes out mostly clean with a few moist crumbs.
Step 6: Cool and serve.
Cool at least 20 minutes before slicing. I love serving Streuselkuchen with coffee, but it is also really nice with tea or a glass of cold milk.
If you are a cookie person too, I totally get it. For another reliable, comforting bake, I also keep this bookmarked for what is the best chocolate chip cookie recipe because it hits that same cozy sweet spot.
Leftovers and Storage
The best part is that Streuselkuchen stays good for days, which makes it perfect for slow weekends or quick weekday treats.
Room temperature: Store covered for up to 2 days. I like using a cake dome or a tightly covered pan. The crumbs stay crispest on day one, but it is still really good day two.
Refrigerator: If your kitchen runs warm, refrigerate it for up to 5 days. Bring slices to room temp before eating so the cake softens again.
Freezer: Freeze slices wrapped individually, then place them in a freezer bag. They keep well for about 2 months. Thaw on the counter. If you want that fresh baked vibe, warm a slice for 10 to 15 seconds in the microwave.
One little personal habit of mine: I like to warm leftover Streuselkuchen and sprinkle the tiniest pinch of salt on top. Not enough to taste salty, just enough to make the sweetness pop. I got into this after reading about the fun uses in what is the pink salt recipe, and now I do it with a lot of desserts.
Variations
Once you have the base down, Streuselkuchen becomes the kind of recipe you can riff on whenever the mood hits. Here are a few simple ideas that still feel true to the classic.
Apple Streuselkuchen: Add a thin layer of sliced apples over the batter, then top with crumbs. Sprinkle with cinnamon. The apples soften and make the cake extra cozy.
Cherry or berry version: Scatter fresh or frozen fruit lightly over the batter. If using frozen, do not thaw. Just toss with a teaspoon of flour first so it does not sink too much.
Vanilla glaze drizzle: Mix powdered sugar with a splash of milk and vanilla, then drizzle after the cake cools. It makes it feel bakery style without much effort.
Extra crunchy topping: Add a couple tablespoons of chopped almonds or pecans to the streusel. It is such a nice texture contrast.
More cake, less crumb: If you are not a heavy topping person, cut the streusel amount by about one third. It will still look and taste like Streuselkuchen, just lighter on top.
Common Questions
Can I make Streuselkuchen the night before?
Yes. Bake it, cool it fully, then cover it. The flavor actually settles in nicely overnight, and it slices even cleaner the next day.
Why did my crumb topping melt into the cake?
Usually the butter was too hot or the crumbs were mixed too much. Next time, let melted butter cool a bit and stop mixing as soon as clumps form.
Is this the traditional yeast version?
This is the easy baking powder version. It still gives you that classic German crumb cake experience, just faster and more weeknight friendly.
How do I know when it is done baking?
The top should be golden and set, and a toothpick should come out with a few moist crumbs. If it is wet batter, it needs more time.
Can I bake this in a 9 by 13 pan?
Yes, just double the ingredients and start checking around 35 minutes. It may take a bit longer depending on your oven.
