Rhubarb Muffins

  • 1 cup light brown sugar packed
  • 1/2 cup vegetable oil
  • 1 large egg room temperature
  • 1 cup buttermilk room temperature
  • 2 tsp vanilla pure
  • 1 1/2 cups rhubarb diced small
  • 1/2 cup walnuts chopped
  • 2 1/2 cups all-purpose flour unbleached
  • 1 tsp baking soda fresh
  • 1 tsp baking powder fresh
  • 1/2 tsp sea salt fine

Rhubarb Cream Cheese Frosting

  • 1 cup rhubarb chopped
  • 1 Tbsp granulated sugar
  • 8 Tbsp unsalted butter room temperature
  • 8 ounces full fat cream cheese room temperature
  • 1 tsp vanilla pure
  • 2 1/2 cups powdered sugar packed

Instructions
 

Rhubarb Muffins

  • Preheat oven to 375 degrees. Add muffin liners to a standard tin and set aside.
  • Beat brown sugar, oil, egg, buttermilk and vanilla in a mixing bowl.
  • Stir in rhubarb and walnuts with a spoon until combined.
  • In a separate bowl, whisk flour, baking soda, baking powder and salt.
  • Add the dry ingredients to the wet and stir with a spoon until just blended. Do not overmix.
  • Distribute batter evenly among muffin liners.
  • If you’d rather skip the icing, you can make a crumble topping by combining a tablespoon of melted butter, 3 tablespoons of brown sugar and a teaspoon of cinnamon.  Sprinkle on muffin tops prior to baking.
  • Bake for 15 to 20 minutes or until muffins are golden brown and a tester placed in the center comes out clean.
  • Keeping the muffins in the pan, place on a wire rack to cool completely.
  • Frosting-free muffins can be stored at room temperature up to 3 days.
  • Store rhubarb cream cheese frosted muffins in an airtight container in the refrigerator up to 3 days.
  • Muffins can be frozen up to 3 months if stored in an airtight container or freezer bag.

Rhubarb Frosting

  • Combine chopped rhubarb, sugar and a splash of water in a saucepan on medium low heat. Stir regularly until rhubarb reduces. Adjust heat to low and continue stirring for 20 minutes until rhubarb thickens into a jam.
  • Transfer rhubarb jam to a glass bowl and cool in the refrigerator.
  • Next, beat butter and cream cheese on high until creamy.
  • Add cooled rhubarb jam and vanilla to cream cheese mixture. Beat until combined.
  • Add powdered sugar ½ cup at a time and beat until smooth.
  • Once muffins have cooled completely, add frosting.
  • Freeze leftover rhubarb cream cheese frosting in a airtight container up to 3 months.
