Preheat oven to 350 F
Make beet puree by boiling or roasting a large beet until fork-tender and blending the small pieces in a food processor.
Mix wet ingredients in a large bowl; beet puree, peanut butter, and egg.
Slowly pour your flour of choice into the bowl and mix well. Add more flour if the dough is wet.
Use a rolling pin to roll out dough on a well-floured surface.
Use cookie cutters to cut out heart shapes in the dough and place them on cookie sheets.
Bake for 20-30 minutes or under golden brown.
Allow the homemade treats to cool on a cooling rack before serving them to your furry friend!
