Method
To prepare the base Separately blend the cashews, almonds and dried coconut into flours using your food processor. Flours should be the consistency of fine breadcrumbs. These are processed separately because they all take different amounts of time to breakdown. Put all the flours back in the food processor together with the dates, vanilla extract, sea salt and lemon rind until combined. The mixture should stick together if it doesn’t, blend a little longer or add a few more dates.
Line a 26 cm x 20 cm baking tin with plastic wrap and firmly press the base mixture evenly into the tin until it is uniformly 1 cm thick. (Plastic wrap is used because once the slice has been refrigerated and set, it is a lot easier to get out). Alternatively you can use baking paper or reuse brown paper bags — which is what we have done here. Our edges are not as uniform but it all tastes the same.
To prepare the topping Blend the oats into a flour in your food processor or blender and set aside. In a high-speed blender, blend oats, ginger juice, ¼ cup coconut sugar, raw agave, maple, vanilla extract and sea salt until smooth.
Blend the cashews, melted coconut oil and ginger powder in the food processor until smooth.
With the food processor still running, take the blended oat and ginger mixture and place into the food processor with the cashew and coconut mixture and blend until combined. Do not over process as the oil might separate.
Fold in 4 tablespoons of coconut sugar by hand.
Pour the mixture over the base and sprinkle with the remaining coconut sugar.
Leave to set in the refrigerator for 5 to 6 hours. Once set cut into squares.
Store in the refrigerator with layers of baking paper between so they do not stick together. That is if you think you will get through it within 5 days. Alternatively store the slice in the freezer, removing slices as you feel, here it will keep for up to 3 months.
