A Cool, Creamy Treat Your Pup Will Fall in Love With. When the weather warms up or your pup deserves a little extra love, these Frozen Peanut Butter & Yogurt Heart Sandwiches are the perfect homemade treat.
Made with just a few wholesome ingredients, these adorable, heart-shaped snacks are creamy, satisfying, and full of dog-approved flavor. Best of all? They’re easy to make, no baking required, and look as cute as they are delicious.
These frozen sandwiches are made with a simple yogurt base and a smooth peanut butter filling, creating a two-layered treat that your dog will absolutely adore.
The outer layers offer cool refreshment and gut-healthy probiotics, while the peanut butter center adds protein and flavor. They’re a great way to beat the heat in the summer or reward your dog with something special any time of year.
And while they look fancy, the prep couldn’t be easier. With the help of a silicone heart mold (or any other shape you like), these treats come together in just a few minutes of hands-on time—then the freezer does the rest. Whether you’re new to homemade treats or you love stocking your freezer with DIY snacks, this one’s a must-try.
What You’ll Need
- 1 cup plain unsweetened yogurt (Greek or regular)
- ½ cup natural, unsweetened peanut butter (xylitol-free)
- 1 tablespoon coconut oil (optional, for easier spreading and added health benefits)
- Silicone heart mold or mini muffin tray
Pro Tips
- Always use xylitol-free peanut butter. This artificial sweetener is toxic to dogs, so check the label carefully.
- Use plain yogurt only. Avoid flavored or sweetened versions which may contain sugar or artificial ingredients.
- Let the first layer freeze partially before adding the peanut butter filling—this helps keep the layers defined.
- Slightly warm the peanut butter to make it easier to spread or pipe into the molds.
- Use a silicone mold for the easiest release and fun shapes. Heart molds are adorable, but any shape will work.
Tools Required
- Silicone mold (hearts, bones, or other shapes)
- Spoon or spatula
- Small mixing bowl
- Measuring cups and spoons
- Freezer-safe container for storing treats
Substitutions and Variations
- Yogurt alternative: Use coconut yogurt or goat milk yogurt if your dog is sensitive to dairy.
- Filling options: Add mashed banana, plain pumpkin, or a sprinkle of cinnamon to the peanut butter for extra flavor.
- Base layer: Mix a bit of blended fruit (like blueberries or strawberries) with yogurt for colorful layers.
- Boosters: Stir in ground flaxseed or a drop of salmon oil to the peanut butter filling for added nutrition.
Make Ahead Tips
These sandwiches are ideal for make-ahead prep. You can freeze a full batch, then pop the treats out and store them in an airtight freezer bag or container. They’ll keep for up to 3 months. Make several flavors at once and label them to rotate throughout the week.
Instructions
1. Fill molds with the yogurt base
Spoon a small amount of plain yogurt into each heart-shaped mold, filling about halfway. Use the back of a spoon to spread evenly.
2. Freeze the base layer
Place the tray in the freezer for 30–45 minutes, or until the yogurt is mostly solid but not rock hard. This step helps keep the sandwich layers clean and separate.
3. Add the peanut butter layer
Slightly warm the peanut butter (and coconut oil if using) until spreadable. Spoon a small amount over each yogurt base, gently pressing it down to form the middle layer.
4. Top with more yogurt
Cover the peanut butter layer with a final spoonful of yogurt. Smooth the top with a spatula to create even, sealed “sandwiches.”
5. Freeze until solid
Return the mold to the freezer and let the treats set completely—about 2–3 hours, or overnight for best results. Once solid, pop the treats out and store in the freezer.
Leftovers and Storage
Store your frozen treats in an airtight freezer-safe container for up to 3 months. Keep frozen until ready to serve. These treats are best served straight from the freezer to avoid melting. For smaller dogs, break in half before offering.
Conclusion
These Frozen Peanut Butter & Yogurt Heart Sandwiches are as cute as they are nutritious. They offer the perfect blend of cooling refreshment, creamy texture, and healthy ingredients that dogs love. With a probiotic-rich yogurt base and a protein-packed peanut butter center, they’re not only fun to make—they’re good for your pup, too.
Perfect for summer afternoons, post-walk rewards, or just a special surprise, these treats are an easy way to show your dog some love. Plus, they store beautifully, so you can always have a stash on hand for your furry friend. Whether you stick with the classic version or get creative with mix-ins, this is one recipe you’ll want to make again and again.
