If you’re looking for a quick, easy, and nutritious snack, these 4-Ingredient Protein Bars are the perfect option!

Made with just a few wholesome ingredients, these bars are a delicious way to fuel your body, whether you’re enjoying them after a workout, as a midday snack, or even for breakfast on the go.
Skip the store-bought protein bars that are often loaded with sugar and preservatives — this homemade version allows you to control what goes into your snack. And best of all? They come together in minutes with just four basic ingredients you probably already have in your pantry!
Ingredients
- 1 cup peanut butter (or almond butter)
- 1/2 cup pure maple syrup (or honey)
- 2 cups rolled oats (quick oats work well, too)
- 1/2 cup protein powder (your favorite flavor)
Optional for Topping:
- 1 cup chocolate chips, melted (for a chocolate coating)
Instructions
- Mix the Wet Ingredients:
In a microwave-safe bowl or on the stovetop, gently warm the peanut butter and maple syrup together until they’re soft and easily combined. This step helps make the peanut butter easier to mix with the dry ingredients. - Add the Dry Ingredients:
Once the peanut butter and maple syrup are smooth, stir in the rolled oats and protein powder until a thick dough forms. If the mixture is too dry, add an extra tablespoon or two of maple syrup or a splash of water to help bind everything together. - Press into a Pan:
Line an 8×8 inch baking pan with parchment paper for easy removal. Press the mixture firmly into the pan, making sure it’s evenly spread out and compact. Use the back of a spoon or your hands to smooth the top. - Optional Chocolate Topping:
If you’re adding a chocolate topping, melt the chocolate chips in the microwave in 20-second intervals, stirring between each interval until smooth. Pour the melted chocolate over the bars and spread evenly. - Chill and Set:
Place the pan in the fridge for at least 1 hour, or until the bars are firm and the chocolate topping is fully set. - Cut and Serve:
Once the bars are set, remove them from the fridge and slice them into rectangles or squares. Store in an airtight container in the fridge for up to 1 week, or freeze for longer storage.
Cooking Tips & Tricks
- Use Different Nut Butters: While peanut butter is a classic choice, you can easily substitute it with almond butter, cashew butter, or even sunflower seed butter for a nut-free option.
- Choose Your Favorite Protein Powder: This recipe works with any protein powder flavor you like. Try chocolate, vanilla, or even unflavored for a more neutral taste. If you’re looking for a plant-based option, feel free to use a vegan protein powder.
- Texture Adjustments: If you prefer a softer protein bar, increase the amount of peanut butter or add a splash of almond milk. For a chewier bar, decrease the maple syrup slightly or add a little extra oats.

Variations & Substitutions
- Add Mix-Ins: Take these protein bars to the next level by mixing in fun ingredients like chia seeds, flaxseeds, shredded coconut, or chopped nuts for extra crunch and nutrition.
- Different Sweeteners: If you prefer, you can substitute the maple syrup with honey or agave nectar for a slightly different flavor. Just be mindful of the sweetness level, as honey is slightly sweeter than maple syrup.
- Oat Alternatives: If you don’t have oats on hand, you can use crushed cereal (like Rice Krispies) or even puffed quinoa for a different texture.
- No-Bake Chocolate Coating: If you’re in the mood for a chocolate-peanut butter combo, top the bars with melted dark or semi-sweet chocolate for a more decadent treat. You can even drizzle it for a lighter coating.
