Pumpkin Oatmeal Bars Recipe

The minute September rolls around, I’m ready for all things pumpkin! These Pumpkin Oatmeal Bars are soft, cakey, and full of cozy fall flavor. They’re like a cross between baked oatmeal and pumpkin cake, but sturdy enough to pick up and eat with your hands.

When my kids were younger, I loved making big pans of homemade snacks like these. I’d cut everything into individual portions, pop them into little snack bags, and have grab-and-go treats ready for lunchboxes, after-school snacks, or busy mornings. It was an easy way to save money instead of buying boxes of individually packaged snacks at the store.

These were always a favorite because they’re yummy enough to feel like a treat, but the oatmeal makes them a satisfying option for breakfast, too. One pan, several days of easy snacks, and a kitchen that smells like fall. That’s my kind of shortcut!

Ingredients

Ingredients & Substitutions

These Pumpkin Oatmeal Bars are made with simple baking ingredients, and they’re easy to adapt depending on what you have in your pantry.

Old-Fashioned Rolled Oats: I originally made these with certified gluten-free rolled oats because my son was eating gluten-free at the time. Regular old-fashioned oats work just as well if gluten isn’t a concern. The oats give these bars their hearty texture while keeping them soft and cakey.

Flour: I’ve made these with both regular all-purpose flour and King Arthur Gluten-Free Measure for Measure Flour. Both have worked well! If you’re making the gluten-free version, be sure to use a gluten-free flour blend intended for 1:1 substitution.

Pumpkin: Use plain pumpkin puree, not pumpkin pie filling. Pumpkin puree gives these bars their moisture and delicious pumpkin flavor.

Spices: Warm fall spices give these oatmeal bars their cozy pumpkin flavor. You can use the spices listed in the recipe or try my Homemade Pumpkin Pie Spice for an easy shortcut. I love keeping a batch mixed up for fall baking!

Supplies

• An 8x8x or 9×9 baking dish
• Mixing Bowl

How to Make Pumpkin Oatmeal Bars

Pin

These pumpkin oatmeal bars are easy to throw together with simple ingredients. They’re perfect for making a big pan at the beginning of the week so you have breakfast and snacks ready to go.

1. Get everything ready. Preheat your oven and prepare your baking pan according to the recipe card below.
2. Mix the dry ingredients. Combine the flour, oats, spices, and other dry ingredients in a large bowl.
3. Add the wet ingredients. Mix the pumpkin and remaining wet ingredients, then combine everything until the batter is evenly mixed.
4. Bake. Spread the batter evenly into your prepared pan and bake according to the recipe card, until the bars are set in the center.
5. Cool and slice. Allow the bars to cool before cutting them into squares or rectangles. They’re soft and cakey but hold together beautifully for grab-and-go snacks.

I like cutting these into individual portions so they’re ready to tuck into lunchboxes or grab for a quick breakfast.

Tips for the Best Pumpkin Oatmeal Bars

• Use old-fashioned rolled oats. They give these bars a wonderful texture without making them feel like a bowl of oatmeal. I originally used certified gluten-free oats, but regular rolled oats work great, too.
• Don’t overbake. These bars are supposed to be soft and cakey, so you don’t want to dry them out. Check for doneness near the end of the baking time.
• Use pumpkin puree, not pumpkin pie filling. They aren’t the same thing! Pumpkin pie filling already contains added sugar and spices.
• Let them cool before slicing. Giving the bars time to cool helps them hold together when you cut them into individual portions.
• Make a big batch! I loved making a whole pan, slicing it into bars, and putting individual servings into snack bags. It made packing lunches and grabbing a quick breakfast so much easier.
• Make them gluten-free. I’ve successfully made these with King Arthur gluten-free flour and certified gluten-free rolled oats. Just be sure your remaining ingredients are gluten-free as well.
• Egg-Free Option: These pumpkin oatmeal bars are easy to make without eggs! Since the recipe only calls for one egg, you can use your favorite egg replacer or substitute 1 teaspoon of baking powder and 2 tablespoons of milk in place of the egg. I’ve made them this way, and they’re just as tasty! The oats help absorb moisture and hold the bars together, even without the egg. If you’re avoiding eggs due to an allergy, be sure to check the labels on your other ingredients, too.

My Kitchen Shortcut: When a baking recipe only calls for one egg, try replacing it with 1 teaspoon of baking powder and 2 tablespoons of milk. I’ve used this trick in all kinds of baked goods over the years, and it works surprisingly well! It’s especially handy when you’re out of eggs or baking for someone with an egg allergy. Just remember that results can vary depending on the recipe.

Optional Mix-Ins

These pumpkin oatmeal bars are delicious just as they are, but it’s fun to change them up depending on what you have in the pantry!

• Raisins: Add a little natural sweetness and chewy texture.
• Dried Cranberries (Craisins): Their sweet-tart flavor is delicious with pumpkin and warm fall spices.
• Homemade Cinnamon Chips: Try my Homemade Cinnamon Chips for little pockets of cinnamon sweetness throughout the bars.
• Chocolate Chips: A fun option when you want something a little more dessert-like.

You can also mix and match your favorites. Pumpkin, cinnamon, and dried cranberries are especially delicious together!

How to Store and Freeze Pumpkin Oatmeal Bars

One of my favorite things about these pumpkin oatmeal bars is how easy they are to make ahead. I used to cut up a big pan, put the individual bars into snack bags, and keep them in a basket on the counter for the kids to grab whenever they wanted something. They rarely lasted long enough for storage to be an issue!

Room Temperature: If you’re planning to eat them the same day, keep the cooled bars covered at room temperature. Because these bars are soft and moist, I recommend refrigerating them for longer storage.

Refrigerator: Store the bars in an airtight container or individual snack bags in the refrigerator for up to 4 days. They’re delicious cold, or you can warm one briefly in the microwave.

Freezer: Yes, you can freeze pumpkin oatmeal bars! I’ve done this when I wanted to make a batch ahead of time. Let the bars cool completely, cut them into individual portions, and wrap or package them in freezer-safe bags. Freeze for up to 3 months for the best quality.

For Lunchboxes: Grab a refrigerated bar when you’re packing lunches and tuck it into an insulated lunchbox with an ice pack. Frozen bars can also be thawed in the refrigerator overnight.

My favorite shortcut? Package them individually before freezing so you can grab exactly what you need without thawing the whole batch.
