Make this the happiest Howl-oween for your pooch with these doggy-decadent “pupcakes.”
Preheat oven to 350°F. Whisk together flour, oats, baking powder, baking soda, and cinnamon in a large bowl. Stir together mashed banana, honey, coconut oil, water, eggs, and 1/2 cup of the peanut butter in a separate bowl. Add banana mixture to flour mixture; stir just until combined.
Pour batter evenly into a 24-cup miniature muffin pan lined with paper baking cups. Bake until pupcakes are cooked through and golden brown, 12 to 15 minutes. Cool completely in pan on a wire rack, about 20 minutes.
Remove pupcakes from pan. Stir together cream cheese and remaining 1/3 cup peanut butter until well combined. Spread frosting evenly over pupcakes, and top evenly with crushed cookies. Gently press in 1 dog bone treat into center of each pupcake.
