2 Right now, I have cooked steel- cut oatmeal, water, banana, cinnamon powder, sugar, and dark chocolate in my cookie batter. 2 cups of cooked oatmeal, 1 banana, half a teaspoon of cinnamon, ~30 grams of chocolate, ~2.5 teaspoons of cane sugar, and enough water so that the batter is somewhat sticky. When I baked it (at 375 degrees Fahrenheit for 10 minutes), however, the cookies came out as leathery, chocolate- flavored skins encasing a blend of bananas and chocolate- flavored oatmeal. It seemed as if the insides hadn't been cooked at all. I tried baking it for an additional five minutes, but doing so didn't change anything. Why did this happen? And what should I do to fix this problem? Thanks in advance! cookies
