What is Irish brown bread?

A typical Irish bread leavened with baking soda instead of yeast. This brown bread, made with whole wheat flour, oats, and treacle (molasses), is a close relative of Irish soda bread, made with white flour.

Originally, brown bread was made with buttermilk, but today’s Guinness bread recipe with stout has recently gained much popularity. Like buttermilk, stout beer is acidic and reacts with baking soda. But, in addition to that, Guinness imparts this Irish bread with a malty, nutty flavor that’s exquisite.

So, the Guinness beer quick bread has a deep, savory, very slightly sweet flavor, and it’s just perfect for breakfast or to dunk into a hot bowl of Irish Lamb Stew.

Recipe ingredients

• Wholemeal flour: For the most genuine results, use coarse whole meal flour or stoneground whole wheat flour in the US.
• Oats: In Ireland, you would use porridge oats, which are similar to old-fashioned oats, also called rolled oats. Don’t use steel-cut oats for this recipe; they take longer to cook and absorb less water, affecting the loaf's consistency.
  • You will need oats for the dough, ½ tablespoon for sprinkling the bottom of the baking pan, and ½ tablespoon for spreading over the dough before baking.

• Brown sugar: It adds just a hint of sweetness.
• Baking soda (sodium bicarbonate) as the leavening agent and fine sea salt or Kosher salt.
• Butter: Irish butter or another full-fat butter. You will need some for the dough and a little knob for greasing the loaf pan.
• Treacle: You can use molasses instead. If you live in Germany, use Zuckerrübensirup.
• Beer: Guinness or another stout beer (See Expert Tips). It’s used instead of regular buttermilk and has the same effect on the dough. Of course, you can replace it with buttermilk, but the bread's flavor and color will be slightly different.

How to make Irish Guinness brown bread?

• Preheat the oven; grease a loaf pan and sprinkle its bottom with oats.
• Melt butter and treacle in a small pan (1). Set aside.
• Combine the dry ingredients in a large mixing bowl: flour, oats, brown sugar, salt, and baking soda (2).

• Combine wet ingredients: Stir stout beer into the melted butter mixture (3).
• Make the dough: Pour the liquid ingredients over the flour mixture and stir well to combine. Use a wooden spoon (4).
• Transfer the mixture to the prepared loaf pan and sprinkle the top of the bread with the remaining oats (5).

• Bake the Irish brown bread for 50 minutes. Then, remove it from the pan and bake it on the baking rack for another 5 to 10 minutes. When done, it should sound hollow when tapped on the underside.
• Cool: Wrap it in a clean tea towel, and let it cool on a wire rack before slicing.

Expert Tips

• The most important tip: Always use a digital kitchen scale in baking; it guarantees for best results (Amazon affiliate link).

• Guinness: You will need 400 ml/ 13.5 oz stout beer for this recipe. A regular-sized bottle contains 330ml/ 11 oz beer; one can usually contains 350 ml/ 12 oz. If you don’t want to open a second container (and drink the rest), replace the missing amount with buttermilk or yogurt.
  • 1 small bottle of stout (330 ml) + 70 ml/ 2.4 fl. oz/ ⅓ cup buttermilk or yogurt
  • 1 can of stout (350 ml) + 50 ml/ 1.7 fl. oz/ ¼ cup buttermilk or yogurt
  • If you do open a second can or bottle to use for the dough, check out more recipes containing Guinness: Dutch Oven Irish Stew and The Best Braised Pork Cheek Recipe.

• Don’t overmix the batter, and don’t leave it waiting after stirring. Stir it quickly; you should be ready in about 30 seconds or less. The baking soda will start reacting immediately, and if you leave the dough waiting, the bread will not rise properly.
