Pumpkin Protein Bars

These pumpkin protein bars immediately put me in the mood for fall and are always one of the first pumpkin recipes I make each year. The combination of pumpkin, oats, and peanut butter creates a soft and chewy texture that reminds me of Perfect Bars. My family kept coming back for more bites when I was testing them, which is always a good sign. A batch is a great way to have an option for quick breakfasts, lunchboxes, and healthy snacks within reach.

Ingredient Notes and Substitutions

These pumpkin protein bars come together from just a handful of items, most of which I keep on hand for healthful breakfast recipes and real-food desserts. Here’s what to gather:

• Oats: Oats are a healthful ingredient, and each type offers different nutritional benefits. For these bars, I use quick-cooking oats (also called quick oats), because they soften easily and create a softer, chewier texture. Old-fashioned oats can be used, too. I just recommend pulsing them first a few times in the food processor to help them break down before adding the other ingredients. Just don’t process them so much that they become oat flour.
• Protein powder: Making homemade protein bars is one of my favorite ways to use protein powder. For this recipe, I recommend an unflavored or vanilla protein powder to avoid overpowering the pumpkin spice flavor. I’ve used both whey protein and plant-based protein, and both work well.
• Pumpkin puree: This adds moisture, nutrients, fiber, and pumpkin flavor. Make sure to use pure pumpkin puree, not pumpkin pie filling, which contains added sweeteners and spices.
• Creamy peanut butter: I recommend natural creamy peanut butter with a smooth, drizzly consistency so it blends easily into the dough. A different creamy nut butter or seed butter, such as almond butter or sunflower seed butter, could also work, though it will change the flavor slightly.
• Honey: This naturally sweetens the bars while also helping bind the ingredients together. I don’t recommend skipping it, since it contributes to both the flavor and texture. Maple syrup will also work, but it changes the flavor slightly.
• Ground flaxseed meal and hemp hearts: These add fiber and healthy fats while helping to bind the bars. 
• Spices: Pumpkin pie spice and cinnamon give these bars their warm fall flavor.
• Mini chocolate chips: These are optional, but I like the little bit of sweetness they add. I prefer dark chocolate chips, but semi-sweet chocolate chips and milk chocolate chips also work well. For a little extra crunch, other nuts and seeds, such as sunflower seeds or chopped pecans could also be pressed into the top of the bars before chilling.

Make It Dairy Free

For dairy-free pumpkin protein bars, I use plant proteins and dairy-free chocolate chips, such as Enjoy Life.

How to Make Pumpkin Protein Bars

With no cooking required and simple steps, these homemade pumpkin protein bars are one of the easiest meal prep snacks I make. My boys have fun mixing and pressing the dough, too. Here’s how all the ingredients come together:

1. Blend the ingredients. Add all the ingredients, except the chocolate chips, to a food processor. Process until everything is well combined and a thick dough forms. I stop and scrape the sides of the bowl once or twice to ensure everything is well incorporated.
2. Shape the dough. Transfer the dough to a parchment-lined loaf pan. I like to use my hands to press it evenly into the pan, making sure it’s firm. I find this helps the bars hold their shape once sliced.
3. Add toppings. If using the chocolate chips, sprinkle them over the dough, gently pressing down to make sure they stick.
4. Chill. Place the pan in the fridge, a minimum of 30 minutes, until the dough is firm and set.
5. Serve. Remove the dough from the pan, and use a sharp knife to slice it into equal-sized bars. I cut my dough into 10 bars, but they can be made smaller or larger, depending on preference.

How to Store

These pumpkin protein bars keep really well, making them great for meal prep. Once sliced, I store them in an airtight container in the refrigerator for up to 7 days. They stay soft and chewy without drying out.

For longer storage, freeze the bars in a freezer-safe container for up to 3 months. To serve, thaw frozen bars in the fridge overnight or at room temperature until they’re soft enough to eat.
