Preheat oven to 350 deg. F. Grease a muffin tin. Whisk together 2 cups whole wheat flour, 1/2 cup barley flour, 1/4 cup sugar, 1+1/2 TB ground flaxseed, 1 TB baking powder, 1 tsp. salt, 1/2 tsp. ground nutmeg. Core and chop 1 large apple. Grate or dice 2 oz. cheddar cheese. Toss apple and cheese pieces with the flour mixture. Add 1+1/4 cup milk, 1/4 cup melted butter, and 1/4 cup water. Stir gently just until dry ingredients are fully incorporated. Divide batter evenly into the 12 muffin cups. Make thin slices from 1 small apple and use these to top the muffins. Sprinkle ground nutmeg over all. Bake 18-20 minutes. Enjoy!
