Ingredients You’ll Need
- 1 ½ cups oat flour: This is the base of your bars, providing a nutritious and gluten-free option. If you don’t have oat flour, you can blend rolled oats into a fine powder.
- ½ cup vanilla, peanut butter, or chocolate protein powder: Choose your flavor to enhance the protein content and taste. If you’re vegan, opt for plant-based protein powder.
- ¼ cup unsweetened cocoa powder: It adds richness and that classic chocolate flavor. Make sure it’s unsweetened to avoid added sugars.
- ¼ teaspoon salt: A pinch to balance the sweetness and enhance flavor.
- ½ cup almond butter or peanut butter (drippy): This is your source of healthy fats, bringing creaminess to the mix. If nut-free, sunflower seed butter works beautifully.
- ⅓ cup agave or maple syrup: For natural sweetness, you can also use honey if it fits your dietary preferences.
- Milk, as needed: I recommend almond milk, but any type will do; just add enough for the perfect texture.
- ½ cup mini marshmallows: These will give your bars that s’mores feel, adding a sweet, chewy texture.
- ½ cup chocolate chips or chopped chocolate: More chocolate means more flavor! Use your favorite variety, dark, semi-sweet, or even dairy-free.
- ⅓ cup crushed graham crackers: A classic s’mores element, they add crunch and sweetness. Gluten-free graham crackers are available if needed.
- ½ cup dark chocolate chips: A final drizzle to make the bars extra special. Melt them down for a lovely glossy finish.
- 1 tablespoon coconut oil: This helps the dark chocolate melt smoothly and gives a nice sheen when drizzled.
How to Make No-Bake S’mores Protein Bars
- Combine Dry Ingredients: In a large bowl, whisk together 1 ½ cups of oat flour, ½ cup of protein powder, ¼ cup of cocoa powder, and ¼ teaspoon of salt until everything is evenly mixed and lump-free.
- Mix Wet Ingredients: In a separate bowl, stir together ½ cup of almond butter, ⅓ cup of agave syrup, and a splash of milk until you have a smooth, glossy mixture. If your nut butter is a bit thick, warm it for 15-20 seconds to make it easier to blend.
- Combine Dry and Wet Mixtures: Pour the dry ingredients into the wet ingredients and stir until a thick, soft cookie-dough texture forms. If it’s too crumbly, add a bit more milk; if too soft, incorporate a little more oat flour.
- Prepare the Pan: Line an 8×4 or 9×5 loaf pan with parchment paper for easy removal. Firmly press the dough into the pan, ensuring it’s packed down to hold together when sliced.
- Add S’mores Toppings: Sprinkle ½ cup of mini marshmallows, ½ cup of chocolate chips, and ⅓ cup of crushed graham crackers over the top, gently pressing them into the mixture.
- Melt Chocolate: In a microwave-safe bowl, melt ½ cup of dark chocolate chips with 1 tablespoon of coconut oil in 30-second increments, stirring in between until it’s completely smooth.
- Drizzle Melted Chocolate: Using a spoon or a zip-top bag with the corner snipped off, drizzle the melted chocolate over the topped bars in decorative ribbons.
- Set in Refrigerator: Refrigerate for 1-2 hours or freeze for 20-30 minutes until firm enough to slice cleanly.
- Slice & Enjoy: Lift the slab out of the pan using the parchment paper and slice into six thick bars (about 18-20g protein each) or eight standard bars (around 14g protein each).
Storing & Reheating
To keep your No-Bake S’mores Protein Bars fresh, store them in an airtight container at room temperature for up to 3 days. If you want to extend their shelf life, refrigerate them, where they can last up to a week. You can also freeze them for up to 3 months. To enjoy frozen bars, simply let them thaw at room temperature for a few minutes. While texture may change slightly, the delicious flavor will remain intact!
Chef’s Helpful Tips
- If your protein bars seem a bit dry, a touch more almond butter or a little coconut oil can help create a creamier texture.
- Make sure the nut butter is smooth and drippy; it makes mixing much easier and gives your bars the desired consistency.
- Allow your chocolate to cool slightly before drizzling to prevent it from melting the toppings.
- Feel free to get creative! Experiment with different protein powder flavors or add-ins like nuts, dried fruit, or seeds.
- For a smoother chocolate drizzle, ensure the dark chocolate and coconut oil are combined thoroughly to avoid clumping.

Recipe FAQs
Can I use other types of protein powder?
Absolutely! You can use whey, plant-based, or flavored proteins like chocolate or vanilla. Just keep in mind that flavored powders may alter the overall taste slightly but can add a fun twist!
How should I crush the graham crackers?
Place them in a zip-top bag and use a rolling pin to crush them into small bits. Alternatively, you can blend them briefly in a food processor for a fine crumb.
Can I make this recipe vegan?
Yes! Replace the honey with agave syrup or maple syrup, and ensure your chocolate chips are dairy-free. Use a plant-based protein powder for the best results.
What should I do if the bars are too crumbly to hold together?
If your bars crumble after slicing, they may need more moisture. Adding a little more nut butter or syrup can help bind them together. Just mix it in gently and press the mixture back into the pan before chilling again.
