1. Preheat oven to 375F/190C
2. Sift the dry ingredients together into a bowl. Set aside.
3. In a stand mixer with a paddle attachment, add in the vegan butter, canola oil and the sugar. Mix until it's creamy and smooth.
4. Add in the mashed banana, plant-based milk, vanilla extract, and lemon zest. Mix until combined.
5. Add in 1/3 of the dry ingredient mixture, and mix until combined. Repeat with another 1/3, and then another 1/3. Mix until it forms a smooth dough.
6. On a baking sheet lined with parchment paper, spoon out about 2 tbsp of dough per cookie. Spread them out 1-2 inches apart.
7. Bake in the oven for 12-13 minutes until the bottoms are golden and the tops are firm to the touch.
8. Remove from the oven and allow to cool on a cooling rack.
9. Combine the ingredients for the glaze. When the cookies have cooled, dunk the top of each cookie into the glaze. Leave to sit until the glaze hardens.
Enjoy :)
