Preheat: Set your oven to preheat at a temperature of 375 degrees and arrange parchment paper on your baking tray.
Combine the Dry Ingredients: In a large bowl, mix the whole wheat flour, oats, dry milk, and cornmeal. If your pup is lactose intolerant, you can easily substitute the dry milk with dried coconut milk to ensure they can still enjoy these tasty biscuits without any digestive discomfort.
Combine the Wet Ingredients: In a medium sized bowl, mix the peanut butter, hot water, and coconut oil. It's crucial to select a natural peanut butter variant for this recipe. Aim for peanut butter without any added sugars or stabilizers, as these are the most beneficial for your pooch. Beware of certain brands that include xylitol in their peanut butter, as this ingredient is hazardous for dogs. Carefully read the ingredients labels. Combine Both: Add the wet ingredients to the dry ingredients and fully incorporate. I find it easiest to use my hands.
Shape the Biscuits: Flatten your dough until it's about 1/2 inch thick. Using a canine-friendly biscuit cutter or a standard cookie cutter, carve out your biscuits and arrange them on the baking tray you've lined with parchment paper. If you don't have a cutter at the ready, you can just shape the dough into small rectangles. Don't worry—your dogs will savor them just the same! If you have leftover dough, simply roll it out again and continue the biscuit-cutting process until no dough remains. Egg wash: Beat the two eggs in a bowl and use this as egg wash, brushing it over the biscuits before baking.
Bake: Place the tray in your preheated oven and bake the biscuits for 25 -30 minutes, or until they turn golden brown. The cooking time will depend on the size and shape of your biscuits.
