Place steak and broccoli into a saucepan. Fill with enough water to cover.
On medium heat, let cook for about 15 minutes. When finished, the steak will be fully cooked.
Transfer cooked steak, broccoli, and 1/2 cup of the fresh beef broth to a blender. Puree until smooth.
Add gelatin powder and mix with a spoon until the gelatin is fully dissolved. I find mixing the gelatin in with a spoon works better vs. simply blending it with the blender.
Place a silicone mold onto a baking sheet for support and spoon the mixture into each mold, filling to the top.
Move to the refrigerator for 1-2 hours, or until fully set.
Remove jello-like treats from the mold. Store in an airtight container in the refrigerator up to 4 days.
