1/2 cup sunflower oil (use olive oil if you're not intolerant)
3/4 cup Stevia blend sugar substitute
2 tsp pure vanilla extract
2 cups rolled oats, ground to flour in a food processor (or any wholemeal flour)
3 tsp baking powder
1/3 cup carob powder (or 1/2 cup cocoa if preferred - contains amines)
2 cups finely shredded zucchini - Don't squeeze out any liquid.
(2 zucchini is about perfect; use the smaller side of the grater.)
Preheat oven to 175C. Oil a slice tray and line with baking paper.
Mix together the oil, stevia blend and vanilla until combined and smooth.
Add in oat flour, baking powder, and sieved carob powder and mix until well combined. It will be dry, but that is fine.
Add lightly beaten egg and grated zucchini. Mix by hand until combined - don't overdo it.
Spread evenly into slice tray and bake for 15-25 mins. The top should look cooked. A skewer will come out with moist bits on it, for a brownie finish. Cook until skewer clean if you want a more cake-like finish.
Optional icing (it really doesn't need it):
Mix 1 TBSP carob powder with 2 TBSP tahini, 3 TBSP pure maple syrup and water to thin
