You can use any form of plant-milk pulp that you like!
Grind one tablespoon flax seeds and add 4 tablespoons water and set aside in the fridge.
Combine in a bowl:
1 1/2 cups okara (or other plant milk pulp) This is about 2 batches!
1/2 cup apple sauce
1/4 cup brown sugar
1/4 cup cocoa powder
1 teaspoon vanilla
Stir until all ingredients are well combined.
Add the flax egg and stir well.
You'll need 1/2-3/4 cups wholemeal flour. This will depend on how moist your pulp is.
Add 1 teaspoon baking powder to the mixture, add 1/4 cup of the flour at a time, and stir gently between each addition. You want the mixture to hold together but still be quite sticky and thick.
Pour mixture into a lined square baking tin.
Crush 1/3 cup macadamia nuts in a plastic zip lock bag. Shake macadamia crumbs over the slice & press in gently with your hands.
Bake at 200C for 25 minutes until mixture is cooked through, you can test with a skewer.
Allow to cool before slicing.
Slice into squares and serve.
