In a bowl add all the ingredients and mix until well incorporate
In a freezer proof container pour the mix, make sure to add some baking paper at the bottom to make it very easy to remove later.
Freeze for ~1 hour (or until solid) and once solid, cut into slices. (You might need to let it defrost for a few minutes before biting into it)

Notes
tip: if your peanut butter is a bit more solid than what it should be, add the bowl with all the ingredients in the microwave for 10secs at a time, stir, and again. This will make the mixing process much easier.
