Need a tasty breakfast or snack to take on the go? These pumpkin peanut butter cereal bars combine creamy peanut butter, pumpkin puree, honey, and warm spices with crunchy cereal for an effortless fall treat. They keep refined sugar low, use wholesome ingredients, and come together quickly — perfect for busy mornings, school lunches, or snack prep.

We love pumpkin this time of year. If you enjoy pumpkin flavors but short on time, try these bars. They’re similar to rice crispy treats in how you assemble them: make the pumpkin-peanut butter base, stir in the cereal, press into a pan, chill until firm, then slice and enjoy.
Make these the night before for an easy grab-and-go breakfast, or make a batch on the weekend and store them in the fridge or freezer. If peanut butter isn’t an option, substitute your favorite nut or seed butter — almond, cashew, or sunflower seed butter all work well and change the flavor in tasty ways.
What’s in Pumpkin Peanut Butter Cereal Bars?
- Peanut butter: use an all-natural “drippy” peanut butter for the creamiest texture.
- Honey: acts as the binder and adds natural sweetness without refined sugar.
- Pumpkin pie spice: adds warm, seasonal flavor.
- Unsweetened pumpkin puree: the real pumpkin flavor — avoid pumpkin pie filling here.
- Plain Cheerios: provide the crisp crunch; other plain oat cereals also work.
- 8×8-inch pan: the right pan size helps the bars set and slice evenly.

Substitutions & Variations
Nut or seed butter: Swap peanut butter for almond butter, cashew butter, or sunflower seed butter if you need a nut-free version. Expect a different but delicious flavor.
Sweetener: Pure maple syrup can replace honey for a vegan-friendly option.
Cereal: Plain Cheerios keep the bars from getting too sweet; cinnamon or pumpkin-flavored cereals add extra fall spice if desired.
Mix-ins: Stir in chocolate chips, dried fruit, or pumpkin seeds for texture and flavor contrasts. Keep mix-ins modest so the bars hold together.

FAQs
Why warm the peanut butter mixture?
Warming the peanut butter, honey, pumpkin spice, and puree melts them together into a glossy, homogeneous binder. That warm mixture coats the cereal evenly and hardens as it cools so the bars hold together.
Can I use pumpkin pie filling instead of pumpkin puree?
Pumpkin pie filling is sweeter and spiced, so it can overpower the recipe. If you use it, reduce any added sweetener to avoid an overly sweet result. Unsweetened pumpkin puree is recommended for the best balance.
Where to find pumpkin puree?
Pumpkin puree is commonly sold canned in grocery store baking aisles or with canned vegetables, especially in fall and winter. If unavailable locally, many online retailers also carry canned pumpkin puree.

Storage
Store leftover bars in an airtight container in the refrigerator for up to 5 days. For longer storage, freeze wrapped bars in freezer bags for up to 3 months. Thaw in the refrigerator or at room temperature before eating.

Serving Suggestions
These bars pair well with coffee, tea, or a yogurt cup for a balanced breakfast. They also work as an afternoon pick-me-up with a smoothie or as an easy school snack in lunchboxes. Try pairing a bar with a salty savory bite (like roasted almonds) to balance the sweetness.

Pumpkin Peanut Butter Cereal Bars — Recipe
Author: Emily Richter
Yield: 12 bars | Prep: 1 hr 10 mins | Cook: 5 mins | Total: 1 hr 15 mins
Ingredients
- ½ cup all-natural, drippy peanut butter
- ½ cup honey
- 1½ teaspoons pumpkin pie spice
- 2 tablespoons unsweetened pumpkin puree
- 3½ cups plain Cheerios (or similar plain oat cereal)
Instructions
- Line an 8×8-inch pan with parchment paper and set aside.
- In a small saucepan, combine peanut butter, honey, pumpkin pie spice, and pumpkin puree. Stir over medium heat until the mixture melts and becomes glossy, about 4–5 minutes. Remove from heat.
- Pour the melted peanut butter mixture over the Cheerios in a large mixing bowl. Stir gently but thoroughly until the cereal is evenly coated.
- Transfer the mixture to the prepared pan. Place another piece of parchment on top and press the mixture firmly into an even layer so the bars hold together.
- Freeze or refrigerate for at least 1 hour, until firm.
- Lift the set mixture out of the pan using the parchment and cut into 12 rectangles or squares. Store chilled or frozen as desired.
Tips & Notes
- Warming the peanut butter mixture ensures the binder coats the cereal evenly and hardens as it cools; don’t skip this step.
- Plain Cheerios keep sweetness balanced. Use flavored cereal if you prefer a sweeter or spicier bar.
- Swap nut butters as needed for allergies or different flavors — almond or sunflower seed butter are great alternatives.
