1-1/2 cups oat bran
1-1/4 cup liquid (nondairy milk, water, or fruit juice)
1/3 cup maple syrup or other liquid sweetener, adjust to taste
1/4 cup vegetable oil
1 cup flour (preferably whole-grain like rice, oat, or spelt)
1 tablespoon baking powder
1/2 cup fruit, or to taste (optional)
1/2 cup nuts, or to taste (optional)
1. Mix oat bran, liquid, sweetener, and oil. Let sit for a couple minutes.
2. Sift in flour and baking powder; mix thoroughly. Add fruit and nuts.
3. Spoon into muffin tin and bake at 400 degrees Fahrenheit for 22 minutes.
Once you've made the recipe a couple times and have the consistency of the batter down, try substituting things like applesauce, cooked pumpkin or mashed bananas for all or part of the liquid, and adding spices like cinnamon (goes well with blueberry muffins, or pumpkin, or apple), cloves or allspice. These muffins have only failed me when I forgot to add the baking powder, and even then they tasted OK.
