Ingredients

  • 56 grams unsalted butter
  • 42 grams molasses
  • 90 grams old-fashioned oats plus more for topping
  • 210 grams whole wheat flour
  • 60 grams all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 50 grams cane sugar
  • 113 grams sourdough discard
  • 334 grams Guinness 1 bottle
  • 56 grams buttermilk

Instructions

  • Prep: Preheat oven to 400 F and line a 9 by 4 inch pan with parchment.
  • Melt butter: Heat up butter and molasses in small saucepan until melted.
    56 grams unsalted butter, 42 grams molasses
  • Make the batter: Whisk together, oats, whole wheat flour, all-purpose flour, baking soda, salt and cane sugar.
    90 grams old-fashioned oats, 210 grams whole wheat flour, 60 grams all-purpose flour, 1 teaspoon baking soda, 1 teaspoon salt, 50 grams cane sugar
  • Whisk together sourdough discard, Guinness and buttermilk until no traces of discard remain.
    113 grams sourdough discard, 334 grams Guinness, 56 grams buttermilk
  • Make a well in the center and pour butter mixture and Guinness mixture in.
  • Stir the ingredients together until no dry bits of flour remain, make sure you scrape the bottom. Don’t overmix. The mixture should look more like a cake batter than a dough.
  • Bake: Pour the batter into the prepared pan. Using a butter knife or paring knife, make a deep, vertical slice through the center of the loaf.
  • Top with more oats.
  • Bake at 400 F for 30 minutes, without opening the oven door, turn the heat down to 350 F and continue baking for another 15 to 20 minutes or until the center of the loaf has set and registers at least 200 F when probed with an instant-read thermometer.
  • Serve: Transfer the loaf to a wire rack, it’s best to let this bread set and cool overnight before slicing.

Notes

  • Make sure your baking soda is not expired before attempting this recipe or your bread may not rise. 
  • Feel free to use active sourdough starter or sourdough discard to make this recipe. 
  • This loaf in an 8 by 5-inch loaf pan or in a 9 by 4-inch Pullman pan
  • Use an instant-read thermometer to make sure your rolls are fully baked. The center of the rolls should measure between 190 F to 200 F when done. 
  • Don’t open the oven door while your bread is baking or your loaf will sink and turn out gummy. 
  • Store any leftover slices of bread in an airtight container at room temperature for up to 3 days.
