Pro Tips for rhubarb crumble streusel donuts
- Fresh Rhubarb:
Use fresh, vibrant rhubarb for the best flavor. Avoid using stale or limp stalks to ensure your donuts are moist and tangy.
- Mixing Method:
Don’t overmix the batter when combining wet and dry ingredients. This keeps your donuts light and fluffy instead of dense.
- Streusel Consistency:
Ensure your streusel mixture is crumbly but not too wet. If it’s too moist, it will clump instead of creating that delightful crunch on top.
- Baking Time:
Keep an eye on your donuts during the last few minutes of baking. Overbaking can lead to dryness; a toothpick should come out clean but moist.
- Cooling Time:
Allow the donuts to cool in the pan briefly before transferring to a wire rack. This helps maintain their shape and prevents sticking.

- Room Temperature: Keep the rhubarb crumble streusel donuts in an airtight container for up to 2 days to maintain their moistness and flavor.
- Fridge: For longer freshness, store the donuts in the refrigerator in an airtight container for up to 5 days; just let them come to room temperature before enjoying.

rhubarb crumble streusel donuts Your Way
Feel free to get creative and customize these delightful treats to suit your tastes and dietary needs!

rhubarb crumble streusel donuts Recipe FAQs
What type of rhubarb should I use for these donuts?
When selecting rhubarb, opt for firm, bright stalks that are crisp and free from blemishes. The tartness of the rhubarb complements the sweetness of the donuts beautifully. If you can’t find fresh rhubarb, frozen works well too—just ensure it’s thawed and drained before using to avoid excess moisture.
Can I substitute buttermilk in this recipe?
Absolutely! If you don’t have buttermilk on hand, you can make a quick substitute by mixing 1/2 cup of milk with 1/2 tablespoon of vinegar or lemon juice. Let it sit for about 5-10 minutes until it thickens slightly. This will achieve a similar tangy flavor and acidity to help your donuts rise perfectly.
How should I store leftover donuts?
To keep your rhubarb crumble streusel donuts fresh, store them in an airtight container at room temperature for up to 2 days. If you need to keep them longer, refrigerate them for up to a week. Just remember to let them come to room temperature before enjoying—they’re best enjoyed warm!
Can I freeze these donuts?
Yes! These delightful treats freeze wonderfully. Once cooled completely, place them in a single layer on a baking sheet and freeze until solid. Then transfer the donuts to an airtight container or freezer bag and store for up to 3 months. When you’re ready to enjoy them, simply thaw at room temperature or warm them up in the oven at 350°F (175°C) for about 5-10 minutes.
What if my batter is too thick?
If your donut batter seems thicker than expected, don’t worry! You can add a splash of milk or buttermilk—about 1 tablespoon at a time—until it reaches a smooth consistency that’s easy to spoon into the donut pan. The batter should be thick but pourable enough to fill each cavity about 2/3 full without spilling over.
