Pre heat the oven to 375F/200C/fan 190C/gas 6. If you have a fan oven, there is no need to pre-heat
Put muffin cases in a 12 hole tin, or use silicone muffin cases that don't need to be put in a tin
Put all the dry ingredients in one bowl, and the wet ingredients in another bowl or jug.
200 g plain flour, 2 tsps baking powder, 80 g oats, ½ tsp salt, 85 g sugar, 280 ml milk, 240 g mincemeat, 90 ml oil
Mix everything well in both bowls, then mix the two together, just enough to combine, mixing too much will make them tough.

Take one out whenever you want one, it will defrost in the microwave in a few seconds.Or pop it in a lunch box still frozen it will be defrosted by the tine you want to eat it.
Variations for easy muffins
Use ReadyBrek type very fine oats instead of ordinary cheap porridge
Or go the other way and use jumbo oats for more texture
Haven't got any oats at all? Just replace the oats with more flour
If you want your muffins to be vegan, use plant milk and baking spread, and check that the mincemeat is vegan, it usually is
