Instructions
- Preheat oven to 400°F (200°C). Line a standard 12-cup muffin tin with paper liners or grease well.
- In a large bowl, whisk together the flour, granulated sugar, baking powder, and salt. Gently fold in the chopped rhubarb until evenly distributed.
- In a separate medium bowl, whisk the egg, milk, vegetable oil, and vanilla extract until just combined.
- Pour the wet ingredients into the dry ingredients. Mix with a spatula until just moistened. Do not overmix; a few lumps are fine.
- If making the streusel: Combine streusel ingredients (flour, brown sugar, cinnamon, and cold butter) in a small bowl. Cut in the butter with a fork or two knives until coarse crumbs form.
- Divide the batter evenly among the 12 muffin cups, filling each about two-thirds full. Sprinkle generously with the streusel topping, if using.
- Bake for 5 minutes at 400°F, then reduce the oven temperature to 375°F (190°C) and bake for an additional 18-20 minutes, or until a toothpick inserted into the center comes out clean.
Notes
For an extra tangy flavor, toss the chopped rhubarb with 1 tablespoon of extra granulated sugar before adding it to the dry ingredients. Ensure the butter for the streusel is very cold for the best crumble texture.
