• 1½ cups diced rhubarb

For the Cinnamon Sugar Topping:

• ¼ cup granulated sugar
• 1 tsp ground cinnamon

Instructions

2. Make the Batter

   In another bowl, combine buttermilk, melted butter, eggs, and vanilla. Pour wet ingredients into dry and stir gently until just combined. Fold in the rhubarb.
3. Fill the Muffin Cups
   Divide batter evenly among the prepared muffin cups, filling each about ¾ full.
4. Add the Topping
   Mix sugar and cinnamon in a small bowl. Brush muffin tops lightly with melted butter, then sprinkle with cinnamon sugar.
5. Bake the Muffins
   Bake for 18–22 minutes, or until a toothpick inserted in the center comes out clean.
6. Cool and Enjoy
   Allow muffins to cool in the pan for 5 minutes, then transfer to a wire rack to finish cooling.

Tips for Success

• Don’t Overmix – Stir just until the batter comes together to keep muffins tender.
