Rhubarb Breakfast Muffins

  • In a large mixing bowl, mix together brown sugar and oil. Then add in 1 egg and vanilla. Beat with a whisk until smooth.
  • Add whipping cream and sourdough discard. Whisk until smooth.
  • In a seperate bowl, combine dry ingredients; flour, baking soda, baking powder, salt, and cinnamon.
  • Add dry ingredients to the wet ingredients until just combined.
  • Fold in rhubarb. (If you are using frozen rhubarb, toss the frozen rhubarb with 1/4 cup flour before folding them in. It helps absorb the moisture)
  • Use a large cookie scoop to scoop into a muffin tray. Makes 12-15 muffins.

Oatmeal Streusal Topping

  • Whisk together flour, oats, sugar, and cinnamon. Add softened butter and use a fork to mix everything together. Top each muffin with 1 tbsp streusel.

Glaze (optional)

Notes

(If you are using frozen rhubarb, toss the frozen rhubarb pieces with 1/4 cup flour before folding them in. It helps absorb the moisture)
