Roughly chop the dates and place in a small bowl or jug. Cover with boiling water and set to one side.
100 g dried dates, boiling water
Preheat the oven to 160 degrees (140 fan)
Melt the butter and honey in a pan. Remove from the heat as soon as the butter has melted. Add the oats and stir well to mix.
50 g butter, 50 g honey, 120 g porridge oats
Line the base of a 20 x 10 cm (1lb) loaf tin with baking paper.
Drain the water from the dates, and blitz to a paste with a hand blender. If you prefer, mash them with a fork.
Spread half of the oat mixture in the base of the baking tin. Firm down with the back of a spoon.
Add the date paste and carefully spread it across the mixture. Top with the remaining oat mixture and firm down gently.
Bake for 20 minutes until golden and set.
Leave to cool in the tin. The oat slices will firm up as they cool. Remove from the tin and cut into 8 pieces (or 6 for a more substantial snack!).
