Step-by-Step Instructions for Buttermilk Rhubarb Muffins with Sugar Crumble

  1. Preheat your oven to 375°F (190°C) and line a muffin tin with paper liners. This ensures even baking and easy cleanup.
  2. In a large mixing bowl, whisk together the flour, baking powder, baking soda, and salt. This step evenly distributes the leavening agents.

  5. Pour in the buttermilk and mix until the batter is smooth. The buttermilk is key to achieving moist Buttermilk Rhubarb Muffins with Sugar Crumble.

  7. Fold in the chopped rhubarb carefully to distribute it evenly throughout the batter.
  8. Divide the batter evenly among the muffin cups, filling each about three-quarters full.
  9. Prepare the sugar crumble by mixing flour, sugar, and butter until it forms a crumbly texture. Sprinkle generously over each muffin.
  10. Bake for 18–22 minutes, or until a toothpick inserted into the center comes out clean. The tops should be golden and slightly crisp.
  11. Allow the muffins to cool in the pan for a few minutes before transferring them to a wire rack.

Tips & Tricks for Perfect Buttermilk Rhubarb Muffins with Sugar Crumble
