Oma's Rhubarb Cake with Streusel is so quick & easy to make. Try making this recipe just like Oma!

Want a rhubarb cake that tastes just like Mutti’s? This rhabarberkuchen mit streusel is quick, easy, and pure buttery bliss. The best part? Streusel on the bottom and the top. If you love shortbread, you’re going to flip for this.

It’s wunderbar with rhubarb, but don’t stop there. Cherries, plums, peaches, just about any fruit gets even better under that golden crumble.

Top Tips For Best Results

1. Use Deep Red Rhubarb: The sweeter stalks make the cake even better
2. No Need to Peel: Just trim, wash, and slice
3. Try Other Fruits: Swap in cherries, plums, or peaches if you like
4. Gluten-Free Hack: Substitute all-purpose flour with a gluten-free blend and use almond flour as directed
5. Vegan Hack: Use plant-based butter suitable for baking

Use Other Fruits? YES!

When using cherries, I like jarred sour cherries. Drain them well and save the juice to mix with sparkling water!

Try sprinkling sliced almonds over the streusel, or add ½ teaspoon cinnamon to the dough for extra flavor.

Using plums? Cut them in half, remove the pits, and place them skin-side down to keep the crust from getting soggy.

How to Pick the Best Rhubarb

When I shop for rhubarb, I always look for stalks that are crisp, firm, and tender. If they feel slimy or look wilted, I pass them by. No one wants sad rhubarb in a cake!

You’ll usually find the best rhubarb in late spring and early summer, but with a good eye, you can spot it year-round.

If I already have some at home, I snap a piece off. If it’s juicy inside, it’s still good. Smaller leaves mean a younger, fresher stalk too ... the fresher, the better, especially for this cake!
