Guinness Soda Bread

Guinness Soda Bread is one of my favorite ways to make a rustic homemade loaf without dealing with yeast or long rising times. I combine wholemeal flour, plain flour, oats, buttermilk, and Guinness to create a hearty bread with a tender crumb and a distinctive malty flavor.

I especially like serving this loaf while it is still slightly warm with homemade whipped sea salt butter. The creamy, salty butter complements the subtle sweetness from the maple syrup and black treacle beautifully. I serve it alongside soups and stews, but I am equally happy enjoying a thick slice on its own.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the Guinness soda bread:

250 g wholemeal flour

280 g plain flour

100 g oats, plus extra for sprinkling

1 tablespoon bicarbonate of soda

2 teaspoons fine salt

250 ml Guinness

250 ml buttermilk

1 tablespoon maple syrup

1 tablespoon black treacle

For the whipped sea salt butter:

100 g unsalted butter, softened

1 teaspoon sea salt flakes

Directions

I preheat my oven to 220°C (fan 200°C/Gas 7) and line a large baking tray with baking paper.

In a large mixing bowl, I combine the wholemeal flour, plain flour, oats, bicarbonate of soda, and fine salt. I mix everything thoroughly so the bicarbonate of soda is evenly distributed.

In a measuring jug, I whisk together the Guinness, buttermilk, maple syrup, and black treacle until everything is well combined.

I make a well in the center of my dry ingredients and pour in the Guinness mixture. Using a wooden spoon, I stir just until a shaggy and slightly sticky dough forms. I avoid overworking the dough because I want the finished bread to remain tender. If it seems too dry, I add a small splash of Guinness. If it is excessively wet, I mix in a little extra flour.

I transfer the dough to my prepared baking tray and use damp fingertips to gently shape it into a round loaf. I flatten the top slightly and make a deep cross across the loaf with the handle of a wooden spoon, being careful not to go completely through the dough.

Then I scatter a few extra oats over the surface and bake the loaf at 220°C for 10 minutes.

I reduce the oven temperature to 190°C (fan 170°C/Gas 5) and bake for another 35–40 minutes. I know my bread is ready when the crust is golden brown and the bottom sounds hollow when tapped.

Next I leave the loaf to cool for at least 15 minutes before slicing. This short resting period helps the crumb finish setting.

While my bread cools, I place the softened unsalted butter and sea salt flakes in a bowl. I whip them with an electric mixer for about 2 minutes, until the butter becomes pale, light, and fluffy.

I serve thick slices of the warm Guinness soda bread with a generous spoonful of whipped sea salt butter.

Variations

Add Seeds:

When I want extra texture, I add a handful of sunflower seeds, pumpkin seeds, or mixed seeds to the dough. I sometimes sprinkle a few over the loaf with the oats before baking as well.

Add Cheese:

For a more savory loaf, I mix grated mature cheddar into the dry ingredients. The sharp cheese works particularly well with the malty flavor of the Guinness.

Make It Slightly Sweeter:

If I want a sweeter bread for breakfast, I increase the maple syrup slightly or add a small handful of raisins. I particularly like this version toasted and spread with butter.

Try Different Oats:

I usually use regular rolled oats because they give the bread a pleasantly rustic texture. I can also use finer porridge oats when I want the oats to blend more seamlessly into the crumb.

Skip the Whipped Butter:

When I want to keep things simple, I serve the bread with ordinary salted butter instead. I also enjoy it with honey, jam, cheese, or alongside a bowl of soup.

Storage/Reheating

Once my Guinness soda bread has cooled completely, I store it in an airtight container or wrap it well. I keep it at room temperature for about 2–3 days. Because homemade soda bread is at its best when fresh, I prefer eating it during the first couple of days.

For longer storage, I slice the cooled loaf and freeze the individual slices in a freezer-safe container or bag. I separate the slices with baking paper when necessary so I can easily remove only what I need. I keep the bread frozen for up to about 3 months.

To reheat individual slices, I put them in the toaster or warm them briefly in the oven. If I am reheating a larger portion of the loaf, I wrap it loosely in foil and warm it in a moderate oven until heated through.

I keep leftover whipped butter covered in the refrigerator. Before serving it again, I let it soften at room temperature so it becomes creamy and spreadable.

FAQs

Can I make Guinness soda bread without yeast?

Yes. I don’t need yeast for this recipe because bicarbonate of soda acts as the raising agent. It reacts with the acidic buttermilk and helps my loaf rise during baking, which is why I can put the dough into the oven shortly after mixing it.

Can I replace the Guinness with another beer?

Yes. I can use another stout or a dark beer with similar roasted and malty characteristics. The exact flavor of my finished bread will change depending on the beer I choose, so I prefer a stout when I want to maintain the rich character of the original recipe.

Why is my soda bread dense?

I expect soda bread to be heartier than a typical yeast loaf, especially when I use wholemeal flour and oats. However, if my loaf turns out excessively dense, I may have mixed the dough too much, used old bicarbonate of soda, or waited too long before putting the mixed dough into the oven. I work quickly and mix only until the dough comes together.

How do I know when Guinness soda bread is fully baked?

I look for a deeply golden crust and then carefully tap the bottom of the loaf. When it sounds hollow, my bread is usually ready. Because ovens vary, I start checking toward the end of the recommended baking time rather than relying exclusively on the clock.

What can I serve with Guinness soda bread?

I particularly enjoy serving this bread with hearty soups, Irish-inspired stews, chili, and other comforting dishes. For something simpler, I serve a warm slice with the whipped sea salt butter. I also like leftover slices toasted for breakfast or served with cheese.

Conclusion

This Guinness Soda Bread is the kind of homemade loaf I turn to when I want something rustic and flavorful without the extra work involved in traditional yeast bread. The combination of wholemeal flour, oats, buttermilk, black treacle, and Guinness gives every slice a hearty texture with rich malty undertones.

The whipped sea salt butter makes the loaf even more satisfying, especially while the bread is still slightly warm. Whether I serve it beside a bowl of soup, add it to a comforting dinner, or toast a leftover slice the next morning, I find this simple soda bread is an easy way to bring the flavors of Irish-style baking to my table.
