Ingredients
- 1 teaspoon active dry yeast
- 1 teaspoon white sugar
- 1 1/2 cups warm water (105-110°F)
- 2 cups all-purpose flour
- 1 cup wheat flour
- 1/8 cup rye flour
- 1/2 cup rolled oats (plus more for topping)
- 1 teaspoon kosher salt
- 1 tablespoon cocoa and espresso powder blend
- 1 teaspoon baking soda
- 1 tablespoon dark molasses
- 9-9.5 ounces Guinness Extra Stout or Draught (about 3/4 of a standard bottle)
- Butter or oil for greasing pan
- 1 egg, beaten (optional, for egg wash)
Instructions
- Proof the yeast: In a glass, combine active dry yeast, sugar, and warm water. Let stand for 5-10 minutes until foamy and bubbling. If mixture doesn’t foam, yeast is dead; start over with fresh yeast.
- Mix dry ingredients: In a large bowl, whisk together all-purpose flour, wheat flour, rye flour, rolled oats, kosher salt, cocoa-espresso powder, and baking soda until thoroughly combined.
- Combine wet and dry: Add molasses and proofed yeast mixture to dry ingredients. Transfer to stand mixer fitted with dough hook. With mixer running on medium speed, gradually add Guinness beer. Mix for 5 minutes until dough forms a smooth ball and pulls cleanly away from sides of bowl.
- First rise: Remove dough from mixer and form into a ball. Cover bowl tightly with aluminum foil. Place in a warm spot (75-80°F) for 1½ hours until doubled in size.
- Shape and prepare pan: Grease a cast iron loaf pan or standard 9×5-inch loaf pan with butter or oil. Lightly knead dough on floured surface to remove air bubbles. Shape into loaf and place in prepared pan. Using a sharp knife, score an X across the top about ¼-inch deep. Brush with beaten egg and sprinkle with additional oats, or dust with rye flour for a rustic finish.
- Second rise: Preheat oven to 120°F (or lowest setting). Place shaped loaf in pan in oven along with a heatproof bowl filled with boiling water. Turn off oven. Let rise for 1½ hours until dough domes above pan rim.
- Bake: Remove bowl of water from oven. Increase oven temperature to 350°F and preheat. Once oven reaches temperature, bake bread for 45-55 minutes until deep golden brown and internal temperature reaches 190-200°F. If top browns too quickly, loosely tent with foil during last 10 minutes.
- Cool: Let bread cool in pan for 10 minutes, then transfer to wire rack to cool completely before slicing.
