Place blackberries and lemon juice in small microwave safe container and cook on high for 4 minutes.
Add the Chia seeds, stir and leave to rest for about 10 minutes.
Preheat oven to 180, and line a 12 hole muffin pan with muffin papers.
In a larger mixing bowl, combine the flour, sugar, coconut.
In a separate jug, mix the milk, oil and egg until thoroughly combined.
Add to the dry ingredients and lightly mix – DON’T over-mix because that makes the muffins tough!
Divide half the muffin mixture between the 12 holes, then put the blackberry mixture in, and then top off with the rest of the muffin mixture. Don’t worry if it doesnt seem to be even on the top – it will work out in the cooking.
Pop in the oven for 20 minutes.
