Peel the banana and break it into chunks. If using a frozen banana, let it sit for a few minutes so it blends more easily. Stir the natural peanut butter well so there are no large oily pockets.
1 large ripe banana, 1/4 cup natural peanut butter
In a blender or food processor, add the banana chunks, plain yogurt, natural peanut butter, and 2 tablespoons of water or low-sodium, onion-free chicken broth. If using pumpkin puree, ground flaxseed or chia seeds, or chopped strawberries, add them now.

Blend on medium speed until the mixture is smooth, creamy, and pourable—similar to a thick smoothie. If the mixture is too thick or the blender struggles, add more water or broth 1 tablespoon at a time until it reaches a pourable consistency.
Check the mixture by smell and texture. It should smell like banana and peanut butter and feel smooth, with no large banana chunks. If chunks remain, blend again briefly for an even freeze.
Place silicone molds, ice cube trays, or small paper cups on a baking sheet or tray for easy transfer. Pour or spoon the mixture into each cavity, leaving a little space at the top for expansion as it freezes.
If you want classic pupsicle shapes, gently press a small dog biscuit, carrot stick, or bully stick into each mold, inserting halfway so it stands upright. If the mixture is very thin, freeze for 20–30 minutes first, then add the sticks so they stay in place.

Transfer the tray with filled molds to the freezer. Freeze for 3–4 hours or until completely solid. Smaller molds or ice cubes will freeze faster; larger paper cups may take up to 6 hours.
Once fully frozen, remove pupsicles from the molds or peel away the paper cups. If they are stuck, briefly run the bottoms of the molds under warm water to loosen. Serve one Woof Pupsicle to your dog in a bowl or on a washable surface, as they may drip while your dog enjoys them.
Place remaining pupsicles in a freezer-safe container or zip-top freezer bag. Label clearly (e.g., "Dog Treats") and store in the freezer for up to 2 months.
