In a high powered blender (I used a Thermomix), blitz the base ingredients until it forms together though is not completely smooth.
Line a loaf tin with baking paper and press the base mix down evenly with the back of a spoon or your fingers.
Clean the blender roughly (it doesn’t need to be spotless!) and add all the middle layer ingredients. Blend until completely smooth, scraping down the sides throughout this blending time. It will form a very thick and sticky consistency, though absolutely delicious! Scrape out onto the base layer, and use the back of a spoon to spread out evenly.
Crush the Inca Inchi seeds with the back of a spoon or the side of a large knife, and then sprinkle over the slice evenly. So the seeds don’t fall of easily once the slice is set, press them down slightly into the mix, just slightly! Dust with cinnamon, using a sifter for an even tone.
Place in the freezer and freeze until firm enough to slice and enjoy.
