How to Make Buttermilk Rhubarb Muffins with Sugar Crumble

Follow these straightforward steps to create tender, flavorful muffins every time.

1. Preheat your oven to 375°F. Line a standard muffin tin with paper liners or lightly grease each cup.
2. Prepare the sugar crumble topping by mixing the white sugar, melted butter, and cinnamon in a small bowl. Set it aside while you prepare the batter.
3. In a large mixing bowl, combine the flour, brown sugar, salt, baking soda, and cinnamon. Stir until evenly distributed.
4. In a separate bowl, lightly beat the egg. Add the buttermilk, oil, and vanilla extract, whisking until blended.
5. Pour the wet mixture into the dry ingredients. Stir gently until just combined. Avoid vigorous mixing, as overworking the batter can produce dense muffins.
6. Fold the chopped rhubarb into the batter. The batter should remain slightly lumpy, which helps ensure light and fluffy results.
7. Fill each muffin liner halfway to three-quarters full. This provides enough room for the muffins to rise without overflowing.
8. Sprinkle the prepared cinnamon sugar crumble evenly over each muffin. The topping will create the signature crunch that makes Buttermilk Rhubarb Muffins with Sugar Crumble so memorable.
9. Bake for approximately 18 minutes, or until the tops are lightly golden and a toothpick inserted into the center comes out clean.
10. Remove the muffin tin from the oven and allow the muffins to cool briefly before transferring them to a wire rack.
11. Serve warm or at room temperature. A little butter spread over a freshly baked muffin makes them even more indulgent.

These easy Buttermilk Rhubarb Muffins with Sugar Crumble come together quickly and reward you with exceptional flavor and texture.

Expert Tips for Perfect Buttermilk Rhubarb Muffins with Sugar Crumble

Even simple muffin recipes benefit from a few professional techniques.

Don’t Overmix the Batter

Overmixing develops gluten and can make muffins tough. Stir only until the ingredients come together.

Chop the Rhubarb Evenly

Small, uniform pieces distribute better throughout the batter and ensure balanced flavor in every bite.

Use Fresh Rhubarb When Possible

Fresh rhubarb provides the best texture and vibrant tartness. Seasonal rhubarb is ideal for these muffins.

Test for Doneness Carefully

Insert a toothpick into the center of a muffin. If it comes out clean or with a few moist crumbs, they’re ready.

Cool on a Wire Rack

Removing the muffins from the pan prevents trapped steam from making the bottoms soggy.

Store Properly

Keep Buttermilk Rhubarb Muffins with Sugar Crumble in an airtight container at room temperature for up to three days.
