Very easy - just get a tub of low fat greek yoghurt (500g tub). Empty the yoghurt into a bowl. Now fill that tub twice with oats and empty the oats into the bowl each time (about 400g oats). Now add in 100g flaked almonds (they generally come in 100g bags), a few drops of almond extract, 1 tsp of salt and 2 tsp of baking soda. Mix well (you may need to add in a glug of milk if quite dry). Now fold in 1-2 packets of raspberries.
Roll the mixture into balls, place on a greased baking tray and bake for 10 minutes at 200 degrees and another 25 minutes at 170 degrees (time depends on your oven, ya know yourself!).
