Line a 28cm x 18cm slice tin with baking paper (making sure you leave plenty hanging over the sides) and preheat your oven to 170 degrees.

In a large bowl, add the rolled oats, rice bubbles, wholemeal flour, coconut and sultanas. Set aside until needed.

Place the butter, honey and peanut butter into a small saucepan and cook over a medium heat until melted and combined.

Once melted, reduce the heat to low and add the brown sugar and vanilla essence and stir to combine.

Pour the melted ingredients into the bowl with the dry ingredients and stir to combine.

Pour the mixture into your slice tin (don't worry it will be quite sticky) and push down with the back of a metal spoon to flatten.

Put the homemade Peanut Butter and Honey Muesli Bars into the oven and bake for 30 minutes or until golden brown.

Allow the muesli bars to cool in the tray for 20 minutes before transferring to a wire rack to cool completely.

Once completely cooled, cut into bars and store in an airtight container.
