Blitz almonds in food processor until roughly chopped. Remove and set aside
Blitz walnuts in food processor until resembles a fine meal.
Add dates, cacoa, vanilla & salt to walnut mixture, and blend together until mixture forms a dough. If mixture is not coming together, try adding some more dates.
In a large bowl, place the roughly chopped almonds & oats. Mix together.
Add date mixture to oats and almonds, and use your hands to mix together.
In a small saucepan, gently heat the peanut butter & honey until smooth and well combined.
Add honey and peanut butter to the date and oat mixture and mix well. *
Press brownie into a loaf or slice tin, and set aside in fridge or freezer until hard.
Cut into slices and serve or store in air tight container in fridge or freezer.
Notes
* I use either a plastic bag to press down the mixture into the tin with my hands to avoid getting food all over my hands and contaminating the brownies.
