Treacle and Oat Bread

Easy·45 min active + 15 min resting

Treacle oat bread is Irish dark soda bread made with oat flour, whole wheat flour, and treacle (molasses) — giving it a deep, malty, slightly sweet character. Dense, dark, and deeply Irish.

Treacle oat bread is a variation of traditional Irish soda bread that uses oat flour and treacle (a byproduct of sugar refining, similar to molasses). The treacle adds both sweetness and the characteristic dark color. This bread belongs to the rural Irish tradition of using whatever grains and sweeteners were locally available.

A dark, dense, slightly sweet loaf with a malty, caramel aroma. The crust is dark; the crumb is moist and heavy. The treacle's flavor is complex — bittersweet, smoky, slightly metallic. With butter, it's deeply comforting.

Oat flour (unlike wheat) contains no gluten, so it produces a denser, more crumbly texture — this is why the bread is dense. The treacle (dark molasses) adds invert sugars (glucose + fructose) that retain moisture (keeping the bread soft for days) and provide the characteristic dark color and malty flavor. The buttermilk-baking soda reaction provides leavening.

Variations

Some add seeds or nuts; the oat-to-wheat ratio varies; some add raisins.

How it's made

6 steps · 45 min active + 15 min waiting

1
3 min
Mix oat flour, whole wheat flour, baking soda, salt.
2
3 min
Rub in butter until crumbly.
3
3 min
Dissolve treacle in warm buttermilk.
4
5 min
Combine wet and dry to form a soft dough.
Watch out
Mix just until it comes together into a soft, shaggy dough — overworking oat-and-buttermilk dough toughens it.
5
2 min
Shape into a round; score a cross.
6
40 min
Bake at 200°C for 35-40 min until dark and hollow-sounding.
Watch out
It's done when the crust is dark and the loaf sounds hollow tapped underneath — the treacle browns fast, so trust the sound over the color.

Baking Sheet

Flat rectangular metal pan (sheet pan, half-sheet, quarter-sheet), 33×23 cm to 45×33 cm, with a low rim. The flat surface gives even heat for cookies, biscuits, roasted vegetables, sheet-pan dinners. Heavy aluminum sheets conduct heat fastest; non-stick coatings make cleanup easier but can warp over 200°C; rimmed half-sheet is the modern American restaurant standard.
