To prepare a strawberry spice loaf, you will first need to prepare your ingredients. You will need: 1 cup rolled oats, 1 tablespoon cinnamon, 1/4 teaspoon allspice, 1/2 teaspoon nutmeg, 2 tablespoons brown sugar, and 1 teaspoon vanilla extract. Preheat the oven to 350 degrees F (180 degrees C) and grease an 8-inch loaf pan with cooking spray. Mix the flour, baking powder, sugar and salt together in the large bowl. Pour the wet ingredients into the dry ingredients and mix until the ingredients are just combined. Bake the loaf for 1 hour and 15 minutes, or until it reaches an internal temperature of 165 degrees Fahrenheit (70 degrees Celsius). Let it cool before removing it from the pan and slicing it into slices.
