What You’ll Need
For the Pumpkin Bars:
- 1 3/4 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 2 teaspoons ground cinnamon
- 1 teaspoon ground ginger
- 1/2 teaspoon ground nutmeg
- 1/4 teaspoon ground cloves
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar
- 1/2 cup brown sugar, packed
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup pumpkin puree (canned or homemade)
For the Brown Sugar Frosting:
- 1/2 cup unsalted butter, softened
- 1 cup brown sugar, packed
- 2–3 tablespoons milk
- 1 teaspoon vanilla extract
- Pinch of salt
Step-by-Step Instructions
Step 1: Prepare the Oven and Pan
Preheat your oven to 350°F (175°C).
Line a 9×13-inch baking pan with parchment paper or lightly grease it to prevent sticking.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, ginger, nutmeg, and cloves. Set aside.
Step 3: Cream Butter and Sugars
In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar together until light and fluffy. This usually takes about 2–3 minutes with a hand or stand mixer.
Add eggs, one at a time, beating well after each addition. Stir in vanilla extract.
Step 4: Add Pumpkin
Mix in the pumpkin puree until fully incorporated. The batter will be thick but smooth.
Step 5: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the pumpkin mixture, mixing until just combined. Do not overmix; you want the bars to remain tender.
Step 6: Bake
Pour the batter into the prepared pan and smooth the top with a spatula.
Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
Allow the bars to cool completely in the pan on a wire rack before frosting.
Step 7: Prepare Brown Sugar Frosting
In a small saucepan over medium heat, melt the butter. Stir in the brown sugar and cook for 2–3 minutes until it bubbles.
Slowly whisk in milk, vanilla extract, and a pinch of salt until smooth. Remove from heat and allow to cool slightly until it thickens to a spreadable consistency.
Step 8: Frost the Bars
Spread the brown sugar frosting evenly over the cooled pumpkin bars.
Cut into squares or rectangles and serve.
Tips for Perfect Pumpkin Bars
- Use pure pumpkin puree
Avoid pumpkin pie filling, which is already sweetened and spiced — it can affect the flavor and texture. - Don’t overmix the batter
Overmixing can make the bars dense. Stir until the flour is just incorporated. - Check doneness early
Ovens vary; start checking at 30 minutes. Toothpick should come out clean or with a few moist crumbs. - Cool completely before frosting
Brown sugar frosting can melt and slide off warm bars. - Adjust spices to taste
If you love extra cinnamon or ginger, feel free to increase slightly — it enhances the pumpkin flavor.
Flavor Variations
Savory-Sweet Twists
- Maple Pecan Pumpkin Bars: Add chopped pecans and a drizzle of maple syrup over the frosting.
- Chocolate Chip Pumpkin Bars: Fold in 1/2 cup semi-sweet chocolate chips before baking.
- Cream Cheese Swirl: Swirl 4 ounces softened cream cheese into the batter for a marbled effect.
Spiced Up
- Extra Pumpkin Spice: Increase cinnamon to 3 teaspoons and nutmeg to 1 teaspoon for a stronger fall flavor.
- Ginger Kick: Add 1/2 teaspoon ground cardamom for an aromatic twist.
Serving Suggestions
- Pair with a hot cup of coffee, chai, or tea for a cozy breakfast or afternoon treat.
- Top with whipped cream for dessert-style indulgence.
- Serve at holiday gatherings or potlucks — these bars are always a hit.
- Make mini bars for lunchbox-friendly snacks or party platters.
How to Store and Reheat
Room Temperature:
Store unfrosted bars in an airtight container for up to 2 days.
Refrigerator:
Store frosted bars in the fridge for up to 5 days. Bring to room temperature before serving for best flavor.
Freezer:
Wrap individual bars tightly in plastic wrap and place in a freezer-safe bag. Freeze for up to 2 months.
Thaw at room temperature and optionally warm in the oven for a few minutes before serving.
Make-Ahead Option
You can bake the pumpkin bars and store them unfrosted in the fridge for 2–3 days.
Prepare the brown sugar frosting fresh before serving to keep it creamy and smooth.
Alternatively, you can freeze unfrosted bars, thaw, and frost just before serving for fresh, indulgent results.
Troubleshooting
Bars too dense:
Make sure your baking powder and baking soda are fresh. Don’t overmix the batter.
Frosting too runny:
Allow the brown sugar frosting to cool slightly before spreading. If needed, add a little more powdered sugar or cook slightly longer to thicken.
Bars dry:
Do not overbake; check a few minutes before the timer is up. Pumpkin puree adds moisture, so overbaking can dry them out.
Frosting grainy:
Stir continuously when cooking the brown sugar mixture and remove from heat as soon as it thickens.
Frequently Asked Questions
Can I use canned pumpkin pie filling instead of puree?

Yes, substitute butter with a vegan alternative, use plant-based milk in the frosting, and replace eggs with flax or chia eggs.
Can I make mini bars or muffins?
Absolutely! Bake in a lined muffin tin or mini baking dish; adjust baking time to 20–25 minutes for mini sizes.
Can I use brown sugar frosting on cupcakes instead?
