Instructions

  1. Preheat your oven to 350 degrees F (175 degrees C). Line an 8x8 inch square baking pan with parchment paper or lightly grease it.
  2. In a large mixing bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, nutmeg, ginger, and cloves until well combined.
  3. Add the pumpkin puree, brown sugar, vegetable oil, egg, and vanilla extract to the same bowl with the dry ingredients.
  4. Gently stir the mixture with a wooden spoon or spatula until just combined; avoid overmixing. The batter will be thick and moist.
  5. Fold in the chopped walnuts evenly throughout the batter.
  6. Spread the batter evenly into the prepared pan, smoothing the top with a spatula.
  7. Bake for 28-32 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
  8. Remove from oven and let bars cool completely in the pan on a wire rack before slicing into 12 bars.
  9. Store bars in an airtight container at room temperature for up to 3 days, refrigerate up to a week, or freeze for up to 3 months.

Tips

Equipment Needed

Essential equipment for making these One-Bowl Spiced Pumpkin Breakfast Bars includes basic baking tools perfect for beginners: Mixing Bowl: Large and sturdy bowl ideal for combining all ingredients in one place. Measuring Cups and Spoons: For precise measurement of flour, spices, and liquids. Whisk or Fork: To evenly blend dry ingredients before adding wet ones.

Ingredient Prep Notes

Use canned pumpkin puree (not pumpkin pie filling) for the best texture and flavor in these breakfast bars. For measuring flour, gently spoon it into the cup and level it off to avoid dense results. For a nut-free version, omit walnuts or substitute with seeds such as pumpkin or sunflower.

Oven Note

Always fully preheat your oven to 350 degrees F (175 degrees C) for even baking and consistent results. Using an oven thermometer can help ensure accuracy. Place your baking pan on the center rack to promote even heat circulation and avoid uneven cooking or overbrowning on edges.

Easy Upgrade Ideas

Boost these simple pumpkin bars with quick and easy upgrades perfect for beginner bakers: Cream Cheese Swirl: Add softened cream cheese drops and gently swirl before baking for creamy tang. Streusel Topping: Mix brown sugar, flour, cinnamon, and butter for a crumbly topping. Dried Fruit: Fold in chopped dried cranberries, raisins, or dates to add sweetness and texture.
