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.
