These big, moist muffins are topped with fresh strawberries, rhubarb and a brown sugar crumble. It’s one of the best strawberry rhubarb recipes when the season comes around.

That’s right, just when you thought you were done eating cake, along comes a batch of giant strawberry rhubarb buttermilk muffins to pull you back in 🙂

Muffins vs. cakes

These jumbo beauties might remind you of a good coffee cake, with their crumbly streusel topping and a buttery, tender texture inside.

But we don’t really believe that muffins are actually a form of cake, do we?

Otherwise we wouldn’t feel so free to indulge in them first thing in the morning!

The great American muffin is actually a traditional quick bread, with a batter leavened with baking powder rather than yeast.

They’re so easy to make and seem to make everyone happy, especially when they’re large and overstuffed with good-for-you ingredients like fresh fruit.

Adding buttermilk to the batter gives the muffins a light, moist texture and since muffins generally have less sugar than cake.

I feel comfortable enjoying them as an all-day, anytime snack.

Let’s just not call them dessert, okay?

What makes these strawberry rhubarb buttermilk muffins so impressive is their generous size.

Since they’re baked in a jumbo muffin tin, they are very shareable.

The batter plus the toppings fill up the muffin cups, so I like to bake these muffins in tulip-shaped parchment paper cups to ensure they keep their shape better (plus they look pretty).

It’s very easy to make your own bakery-style liners out of parchment paper — cut 6-inch squares of paper to fit a jumbo pan, or 5-inch squares to fit a standard muffin pan (here’s a step-by-step video showing how to do it),

Don’t worry if all you have are regular cupcake liners or even no liners at all — just be sure to oil your muffin pan thoroughly, including the top of the pan.

Servings 6 muffins


Streusel Crumble:
  • 5 tablespoons (75 g) unsalted butter, melted
  • ¾ cup (100 g) all-purpose flour
  • ½ cup (110 g) light brown sugar
  • ¼ teaspoon fine sea salt
  • 8 ounces (225 g) strawberries, hulled and chopped
  • 2 stalks rhubarb, 6 - 8 ounces, diced
  • ¼ cup (32 g) cornstarch
  • 2 tablespoons light brown sugar
  • 1 teaspoon lemon juice
  • 2 cups (240 g) all-purpose flour
  • ½ cup (100 g) granulated sugar
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • ½ teaspoon fine sea salt
  • Grated zest from 1 orange or lemon
  • 1 egg, lightly beaten
  • ¼ cup (60 ml) canola oil
  • 2 tablespoons unsalted butter, melted
  • 1 cup (250 ml) buttermilk
  • 2 teaspoons vanilla extract


  • Preheat the oven to 400 degrees (200C) with a rack positioned in the middle. Oil a 6-cup muffin tin and fill with muffin liners or tulip-shaped parchment liners.
  • Place the ingredients for the streusel in a bowl and mix until it forms large, moist crumbs. Set aside.
  • Put the strawberries, rhubarb, cornstarch, brown sugar and lemon juice in a bowl and gently stir to combine. Set aside while you mix the rest of the batter.
  • In a large bowl, whisk together the flour, sugar, baking powder, baking soda, salt and grated zest. Make a well in the center and stir in the egg, oil, butter, buttermilk and vanilla. Mix until the batter just comes together and the flour is incorporated.
  • Divide the batter evenly into the muffin cups. Spoon the strawberry mixture evenly over the batter (about 1/2 cup for each cup), then top with the streusel crumbs (2 tablespoons or so per cup)
  • Bake 22 - 27 minutes, until the muffins are golden brown on top and a toothpick inserted into the center of the muffins comes out with a few moist crumbs.


  • The recipe makes 6 jumbo "Texas" style muffins or 12 standard-size muffins.
  • The muffins keep well for a few days, wrapped or stored in a covered container.

    This is an elegant muffin. I appreciated your clear instructions and the video on the parchment liners. Altitude adjustments of slightly more egg/buttermilk and slightly less sugar/leavening/heat worked for me at 5,000 ft. Thank you!

    1. So glad you liked them Christine! Thanks for sharing the tip for altitude baking, too 🙂
