This traditional Irish soda bread recipe with buttermilk uses a blend of all-purpose and cake flour with cream of tartar for a golden crust and soft, tender crumb. For a rustic boule that slices beautifully warm.
3cupsall-purpose flour (spooned and leveled) 360 grams
1cupcake flour120 grams
2tablespoonsgranulated sugar25 grams

3tablespoonssalted butter (2 tablespoons softened for dough, 1 tablespoon melted for brushing ontop after baking)42 grams
1½cupsbuttermilk (full-fat)360 grams
Instructions
Heat the oven – Set it to 400°F and move the rack to the upper-middle position. This is where the crust builds that deep golden color without burning the bottom.
Mix the dry ingredients – Whisk the all-purpose flour, cake flour, granulated sugar, baking soda, cream of tartar, and salt together in a large mixing bowl until evenly combined.
Work in the butter – Drop in the 2 tablespoons of softened butter and work it in with a fork or your fingertips until the mixture looks like coarse, uneven crumbs. You want it to look a little shaggy, and if you can still see large chunks of butter, keep working it another minute.
Add the buttermilk – Pour it in and stir with a fork until the dough pulls together into a shaggy mass. Stop the moment no dry flour remains, it looks rough and that's exactly right.
Turn and knead gently – Turn the dough onto a lightly floured surface and knead 4 to 5 times until it holds together. Stop there, overworking it toughens the crumb.
Shape the loaf – Pat the dough into a round about 6 inches across and 2 inches high. Keep the thickness even, that's what bakes the center and edges at the same rate.
Score and set up – Set the loaf on a parchment-lined baking sheet or into a greased cast iron skillet. Cut a cross about ¼ inch deep across the top, running nearly to the edges.
Bake and tent at 20 minutes – Bake at 400°F for 20 minutes. Tent loosely with foil, drop the oven to 375°F, and bake another 20 to 25 minutes until deep golden brown.
Check for doneness – Push a skewer through the center, it should come out clean. Tap the bottom, it should sound hollow. Check the thermometer, it should read 190°F. All three together and you're done.
Brush, rest, and serve – Brush the hot crust immediately with the remaining tablespoon of melted butter, move to a wire rack, and rest 30 to 40 minutes before slicing. Serve warm with salted butter alongside Irish stew, or toast thick slices the next morning with jam.
