How to Make rhubarb crumble streusel donuts
1. Preheat the oven to 350°F (175°C) and grease the donut pan. This step ensures your donuts come out easily and have a perfect golden-brown color.
2. Whisk together 1 cup of all-purpose flour, 1/2 cup of granulated sugar, 1 teaspoon of baking powder, 1/2 teaspoon of baking soda, and 1/4 teaspoon of salt in a mixing bowl. This dry mixture will create the base for your fluffy donuts.
3. Combine in another bowl: 1 large egg, 1/2 cup of buttermilk, 1/4 cup of melted unsalted butter, and 1 teaspoon of vanilla extract. Whisk until well blended to infuse your batter with rich flavors.
4. Pour the wet ingredients into the dry ingredients and gently mix until just combined. Be careful not to overmix—this keeps your donuts light and airy! Then, fold in 1 cup of chopped rhubarb for that delightful tartness.
Make the Streusel Topping:
5. Mix together 1/2 cup of all-purpose flour, 1/4 cup of packed brown sugar, and 1/2 teaspoon of cinnamon in a small bowl. This combination adds a warm, spicy sweetness to your topping.
6. Add the cold cubed butter (1/4 cup) and use a fork or your fingers to combine until crumbly. The texture should resemble coarse crumbs—this will create that irresistible crunch on top!
Bake the Donuts:
7. Spoon the batter into the prepared donut pan, filling each cavity about two-thirds full. This allows room for rising while ensuring they maintain their shape.
8. Sprinkle the streusel topping evenly over the batter in each cavity, making sure every donut gets its fair share of that crunchy goodness.
9. Bake for 12-15 minutes or until a toothpick comes out clean when inserted into the center of a donut. You’ll know they’re done when they’re lightly golden on top!
10. Allow the donuts to cool in the pan for about 5 minutes before transferring them to a wire rack to cool completely. This prevents sogginess and keeps them perfectly fluffy.
Optional: Dust with powdered sugar for an extra touch of sweetness!

Pro Tips for rhubarb crumble streusel donuts
- Fresh vs. Frozen Rhubarb: Use fresh rhubarb for the best flavor, but if using frozen, thaw and drain excess moisture to avoid sogginess.
- Proper Mixing: Mix wet and dry ingredients until just combined; overmixing can lead to dense donuts. Gently fold in the rhubarb for a light texture.
- Streusel Crumble: Ensure butter is cold when making the streusel topping for that delightful crunch. If it’s too warm, it won’t hold its shape while baking.
- Even Filling: Fill the donut pan cavities about 2/3 full to allow room for rising without overflowing, ensuring perfect-shaped rhubarb crumble streusel donuts.
- Toothpick Test: Check doneness by inserting a toothpick into the center; if it comes out clean, the donuts are ready. If wet batter clings, bake a few extra minutes.
