These strawberry rhubarb muffins have a thick, crumbly topping. They're an easy treat to make during strawberry and rhubarb season.

Topped with a cookie-like crispy, crumbly topping, these muffins are best served fresh out of the oven or at room temperature. A moist and tender batter with chunks of sweet strawberries and tart rhubarb inside makes them the perfect muffin. They’re a sweet treat with some healthy ingredients like whole wheat flour, rolled oats, strawberries and rhubarb.

I love baking with local seasonal fruits because every season brings something to look forward to. You’ve got to get what’s in season while you can! Rhubarb and strawberries are in season in summer from May to August so I stock up and make batches of these muffins. It’s definitely worth turning the oven on in the summer for these!

The natural sweetness of strawberries pairs beautifully with the zingy tartness of rhubarb creating a perfect irresistible sweet-tart flavour in baked goods. You can also check out my Strawberry Rhubarb Crisp that uses the same combination.

Can I use frozen rhubarb and strawberries?

If you can’t get fresh then yes, frozen rhubarb and strawberries can be used. Do not thaw – use from frozen. They may exude more liquid than fresh, therefore when combining them in a bowl, toss them with one additional tablespoon of flour.

Can I add more rhubarb and strawberries to the recipe?

It may seem tempting to bulk up the muffins with more fruit, but I recommend you keep the ratio of rhubarb and strawberries exactly as directed in the recipe. This keeps the balance of fruit and muffin batter at the right consistency and ensures a perfectly baked muffin that sets.

Can I use any other type of fruit in these muffins?

You can replace the total amount of fruit in the recipe with any mixed berries, diced pears, apples or peaches and the muffins will be just as delicious! The crumble topping would pair beautifully with any of those fruits.

How do I store these muffins?

Store cooled muffins in an airtight container and keep them at room temperature for 3 days or in the refrigerator for up to 5 days. Once the muffins are stored this way, the topping will moisten. If you prefer to keep the topping crisp, freeze the muffins immediately after they’ve cooled in an airtight container for up to 2 months. To thaw frozen muffins, transfer the muffins to a rack and thaw at room temperature and the topping will still be crisp!

I generally love all kinds of muffins because they’re so forgiving; they can be made super healthy or with a little decadence like these ones. Give this recipe a try and I guarantee everyone will enjoy these sweet crumbly muffins!

I’ve baked so many different muffin types that I’d need more than two hands to count them. Check out more great muffin recipes from the blog:
