Directions
- Preheat the oven to 160°C / 325°F.
- Grease and line a baking tin, about 20cm square. Put the butter, sugar, peanut butter, honey and grated citrus zests in a deep saucepan over a very low heat. Leave until melted together, stirring from time to time. Remove from the heat. Stir the oats and muesli into the melted butter mixture until thoroughly combined. Spread the mixture evenly into the baking tin, smoothing the top as you go.
- Bake for about 30 minutes until golden in the centre and golden brown at the edges.
- Leave to cool completely in the tin (it cuts much better when cold), then turn out and cut into squares. These bars will keep for 5–7 days in an airtight container. For something different, replace the peanut butter with 1 medium-ripe banana. Mash the banana and stir it in after all the other ingredients have been combined.
