This is from Susan Reimers book, which is fab if you want to buy a muffin book. My modifications are in brackets after the ingredients.
200g flour (half plain/half wholemeal)
1.5 tsps baking powder
0.5 tsp salt
85g rolled oats
240 ml low-fat yogurt (about 2/3 of a big container)
1 tsp bicarb of soda
1 egg, beaten with a fork
110-140g light brown soft sugar (70-90g Fruisana and 1tsp blackstrap molasses)
90-120 ml milk (150 ml)
90 ml veg. oil or 85g melted butter (45 ml oil)
up to 140g fruit or berries
Preheat oven to 190-200C (180 for my fan oven)
Sift flour, baking powder and salt into large bowl
In a separate bowl stir together oats, yogurt and bicarb of soda, allow to stand for a minute (it's great it sort of fizzes up) then add beaten egg, sugar, milk and oil and stir well.
Pour wet mix into the flour mix. Stir gently until just combined and there is no visible dry flour, don't over stir. Add fruit on the last couple of stirs.
Spoon into tins immediately and bake for 20-25 mins (if making 12, 30-35 mins if making 6 jumbo muffins) until tops are brown.
These will definitely fall apart if you try to turn them out of a silcone tray when they're still hot, but are fine when cool. They freeze really well and are yummy if you defrost them in a microwave and crisp them in the oven at 100C for 10 mins.
