I tried making a zero waste cake

Ok so I guess zero waste baking was made a little bit easier by the zero waste shop. I know there is probably going to be an army of zero wasters who will tell me I have done something wrong, but I did my best!
Lemme know if you have any good zero waste recipes?!
My recipes (which I don't reccommend at all because I just freestyled them and haven't played around to get the perfect recipe yet)
Cookies:
1 avocado
100g sugar
1 egg and 1 egg yolk (you can use the egg whites to make meringues!)
110g cocoa powder
60g Almonds
1/2 Teaspoon Baking powder
40g Oat flour
mash your avo add the sugar. Then add your eggs. Sieve cocoa powder and baking powder, and mix in the rest of the ings. Bake in fan oven at 160 for 11 mins (or until baked to your preference.

Cake:
1 Orange boiled for 2 hours
3 eggs
125g Ground Almonds
125g Caster Sugar
2 tablespoons Water
25g Cocoa Powder
1 teaspoon Baking Powder
Boil orange for 2 hours. WHen boiled take out and cut into quarters, placing in blender and blend until a pulp is formed.
Whisk up eggs until frothy, add in caster sugar and whisk again. Sift in cocoa powder + Baking powder, add in remaining ingrediients and whisk until combined.
Pour in to a greased 7inch cake tin (i did this and then made the 3 extra cupcakes but you may want to play around with scales and a bigger cake tin!)
Bake for 30 mins at 170 fan (or until a knife comes out clean.
Allow to cool for 5 minutes then turn out on to a wire cooling rack.
