1Preheat your oven to 180°C conventional / 170°C fan / Gas Mark 4.
2Grease and line a 2 lb loaf tin.
3In a large mixing bowl, thoroughly combine the plain flour, coarse wholemeal flour, oat bran or finely ground oats, salt and bread soda.
4Add the porridge oats, soft brown sugar, sunflower seeds, pumpkin seeds, linseed and sesame seeds if using. Mix everything together.
5In a separate jug, lightly beat the egg.
6Whisk in the rapeseed oil and black treacle until combined.
7Add 375ml of buttermilk to the wet ingredients and stir.
8Pour the wet mixture into the dry ingredients. Mix gently until everything is just combined. Be careful not to overmix.
9If the mixture feels too stiff, gradually add a little more buttermilk. You want a soft, moist mixture that is easy to spoon into the tin, but not runny.
10Spoon the mixture into your prepared loaf tin and smooth the top.
11Sprinkle with porridge oats and your chosen seeds. Make a shallow cut along the centre of the loaf.
12Bake for approximately 55 to 65 minutes, until beautifully browned and cooked through.
13Check with a skewer inserted into the centre. It should come out clean or with just a few dry crumbs.
14Remove from the tin and allow to cool completely on a wire rack before slicing.

Tips
You can replace the rapeseed oil with 3 tablespoons melted butter or mild olive oil if you prefer.
You can leave out the sunflower, pumpkin, linseed and sesame seeds completely for a seed-free loaf. Because seeds absorb some moisture, you may need slightly less buttermilk (around 350 to 375ml should be sufficient).
Enjoy a thick slice with proper Irish butter, or serve it alongside a steaming bowl of homemade vegetable soup.
