This is a super easy recipe I have used successfully in my breadmaker.
3 cups plain flour or bakers flour
2 tsp bread improver
2 tsp yeast
1.5 cups steel cut oats (or fast cooking oats)
pinch of salt
3-4 tsp brown sugar
1/2 cup linseed, or oat bran, or chia bran (optional)
1/4 cup olive oil
Warm water to combine (about 1.5 to 2 cups)
Dissolve the sugar in 1 cup of the water.
Add to all the other ingredients in the bread maker.
Turn on. Watch the kneading process for a few minutes, adding enough water slowly (literally in small drips) to allow the dough to form a ball. The ball should be slightly sticky and wet as the oat and bran will soak up some water over time.
Let the cycle finish.
The oat actually ends up "dissolving" into the bread from the kneading process, which I like. If you prefer a more grainy texture, you can add the oat just before the proofing cycle after the kneading is complete.
