First line a 12 hole muffin tin with muffin cases and pre-heat the oven to 170°C.
Prepare the streusel by placing the flours, sugar, butter, oats and spice in a large mixing bowl and rubbing together between your fingers. The streusel should come together but still be crumbly. Set aside whilst you prepare the muffin batter.
Pour the mincemeat, apple puree, sugar, eggs and olive oil into a large mixing bowl and beat together until combined.
In another mixing bowl sift together the flours, spice, bicarbonate of soda, baking powder and salt in a mixing bowl, then tip into the liquid batter.
Beat together for a minute or so until everything is well mixed then evenly distribute between the muffin cases.
Crumble the streusel on top of the muffins then bake in the oven for 22-24 minutes.
Remove from the oven and immediately remove the muffins from the tin and leave on a rack to cool.
