These crispy tart rhubarb muffins feature a perfectly crisp crust and a crunchy streusel topping, balancing tartness and sweetness for a delightful treat perfect for spring gatherings or any time you want a quick, easy, and delicious muffin.
Do not overmix the batter to avoid tough muffins; keep streusel butter cold for crunch; drain excess liquid from frozen rhubarb to prevent sogginess; start checking muffins at 22 minutes to avoid overbaking; muffins can be stored at room temperature for 2 days or frozen for longer storage; reheat in oven to restore streusel crunch.
