1. Preheat your oven to 350°F and line a baking sheet with parchment paper—trust me on using parchment, or you’ll be struggling with stuck sandwich treats while your pup does impatient deli spins.
2. In a large mixing bowl, combine rolled oats, mashed kidney beans, grated carrot, and egg. Mix these base ingredients until your dog starts doing his gourmet sandwich dance from the incredible deli aroma.
3. Slowly add chicken broth to achieve dough-like consistency that’s rollable but not too wet. The mixture should hold together beautifully for sandwich construction.
4. Roll out dough and cut small circles using cookie cutter. Place half on prepared baking sheet, add filling spoonfuls to each, cover with remaining circles, and press edges to seal sandwiches.
5. Bake for 20-25 minutes, checking at 18 minutes, until firm and golden. They’re done when they smell like a high-end dog bakery.
6. Let cool completely before serving—about 20 minutes if your pup can wait that long for sandwich treats. Always let cool completely to allow sandwich structure to set properly.

Notes

• Always let cool completely before serving to prevent burns and allow sandwich structure to firm properly
• Amber prefers these when the layers have had time to set and the flavors have melded into perfect sandwich harmony
• Press edges firmly during construction to prevent sandwich separation during baking

Storage Tips

• Store in airtight container at room temperature for 1-2 weeks maximum
• Handle gently to maintain sandwich structure integrity
• Keep layers intact for optimal presentation and eating experience

What Makes This Recipe Special

These treats combine fiber-rich oats that create perfect “bread” texture with plant-based protein from kidney beans for satisfying “filling.” The sandwich construction provides multiple textures and flavors in every bite while the interactive format makes treating more engaging—way better than flat treats that lack the creative presentation and layered nutrition.
