Low-Sugar Oatmeal Strawberry Muffins With Sourdough Discard

If you love fruit-filled, nourishing muffins with bursts of berry flavor, these sourdough oatmeal strawberry muffins are for you! Whether you immediately bake or enjoy them after a long fermentation in the fridge, they’re moist, flavorful, and packed with gut-healthy ingredients.

  • Prep: 10 minutes
  • Cook: 30 minutes
  • Total Time: 40 minutes

Ingredients

  • 1 1/2 cups all-purpose flour
  • 1/2 cup rolled oats
  • 1/3 cup sugar
  • 1/2 teaspoon baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 1 1/2 cup strawberries, sliced
  • 1/2 cup grass-fed butter, room temperature soft
  • 1/2 cup sourdough starter, room temperature*
  • 2 teaspoons lemon juice
  • 1/2 tsp lemon extract
  • 1/2 cup whole milk, room temperature
  • 2 eggs, room temperature
  • Extra fresh strawberries for topping

Instructions

  1. Preheat your oven to 350° F.
  2. Line a muffin tin with paper liners.
  3. In a medium-large mixing bowl, combine the flour, oats, sugar, baking soda, baking powder, salt, and strawberries.
  4. In a separate bowl, combine the butter, sourdough starter, lemon juice, lemon extract, whole milk, and two eggs. Whisk until combined.
  5. Gently fold the wet ingredients into the dry ingredients until everything is just combined. Do not over-mix. The batter should be thick, and it’s okay if there are clumps.
  6. Spoon the batter into the muffin tins. Optional— top with fresh strawberry slices.
  7. Bake for about 30 minutes total. Rotate the pan halfway through.
  8. Allow cooling for about 15 minutes.

Notes

  • You can use active starter or discard from the fridge. Either way it is “discarded” into the recipe since it is not used for rise. Make sure it’s room temp before mixing into the wet ingredients for best results.
