Perfect for a healthier snack or breakfast option, they rely on natural sweetness from pumpkin and just a touch of sugar, making them ideal for those watching their sugar intake without sacrificing flavor.
Ingredients
- 1 cup whole wheat flour
- 1/2 cup all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 1 1/2 teaspoons ground cinnamon
- 1/2 teaspoon ground nutmeg
- 1/4 teaspoon ground cloves
- 1/4 teaspoon ground ginger
- 1/3 cup coconut sugar (or light brown sugar)
- 1/4 cup unsweetened applesauce
- 1/4 cup plain Greek yogurt
- 1 large egg
- 1 teaspoon vanilla extract
- 1 cup canned pumpkin puree (not pumpkin pie filling)
- 1 cup finely grated zucchini (about 1 medium zucchini, excess moisture squeezed out)
- 1/3 cup chopped walnuts or pecans (optional)
- Optional: 1/4 cup raisins or dried cranberries (unsweetened)
Instructions
- Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease it.
- In a medium bowl, whisk together the whole wheat flour, all-purpose flour, baking soda, baking powder, salt, cinnamon, nutmeg, cloves, and ginger until evenly combined.
- In a large bowl, beat the egg lightly. Add the coconut sugar, applesauce, Greek yogurt, and vanilla extract; mix well until smooth.
- Stir in the pumpkin puree until fully incorporated.
- Fold in the grated zucchini, making sure excess liquid has been squeezed out to avoid sogginess.
- Gradually add the dry ingredients to the wet ingredients, folding gently until just combined. Do not overmix to keep the bars tender.
- If using, fold in the chopped nuts and dried fruit evenly into the batter.
- Pour the batter into the prepared pan, spreading it evenly with a spatula.
- Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs.
- Remove from oven and let the bars cool completely in the pan on a wire rack before slicing into 12 bars.
Tips
- Grate and drain zucchini well: After grating, place zucchini in a clean kitchen towel or cheesecloth and squeeze out as much moisture as possible to prevent soggy bars.
- Sweetener substitutions: You can swap coconut sugar for light brown sugar, maple syrup (reduce applesauce slightly), or a granulated sugar substitute like erythritol for a lower glycemic index.
- Flour swaps: Use all-purpose flour only if you prefer a lighter texture, or substitute oat flour for a gluten-free option (note baking times may vary).
- Don’t overbake: Bars continue to set as they cool. Remove from oven once a toothpick shows moist crumbs to avoid dryness.
Serving Suggestions
These pumpkin zucchini bars are delicious on their own as a grab-and-go snack or breakfast. For an extra touch, serve them with a smear of almond butter or a dollop of Greek yogurt. They also pair well with a warm cup of chai tea or coffee, complementing the fall spices perfectly. For a more indulgent treat, drizzle lightly with honey or a low-sugar cream cheese frosting.
Variations
You can easily customize these bars to suit your taste or dietary needs. Add 1/4 cup of mini dark chocolate chips for a richer flavor without too much added sugar. Swap walnuts for pecans or sunflower seeds to change the texture. For a vegan version, replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, set for 5 minutes) and use dairy-free yogurt. To increase protein, add a scoop of vanilla protein powder, adjusting flour quantities slightly to keep the batter balanced.
Storage and Reheating
Store these bars in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to 1 week or freeze for up to 3 months. To freeze, wrap bars individually or in portions in plastic wrap and place them in a freezer-safe container or bag. Thaw overnight in the refrigerator or at room temperature for an hour before serving. Reheat briefly in a microwave (15-20 seconds) if you prefer them warm.
Frequently Asked Questions
Can I use fresh pumpkin instead of canned?
Yes, you can use fresh pumpkin puree made by roasting and pureeing pumpkin flesh. Be sure to cook it down slightly to reduce excess moisture, as fresh pumpkin tends to be wetter than canned.
What if I don’t have Greek yogurt?
You can substitute plain yogurt, sour cream, or buttermilk in equal amounts. For a dairy-free option, use coconut yogurt or a non-dairy yogurt alternative, but note it may slightly alter texture and flavor.
Are these bars gluten-free?
Not as written, since they contain whole wheat and all-purpose flour. To make gluten-free bars, replace the flours with a gluten-free flour blend and add 1/2 teaspoon xanthan gum if your blend doesn’t already contain it.
How do I know when the bars are done baking?
Insert a toothpick into the center; it should come out with a few moist crumbs but not wet batter. The bars will also spring back lightly to the touch. Avoid overbaking to keep them moist.
Can I make these bars ahead of time?
Absolutely. They hold up well stored in the fridge for up to a week and freeze beautifully. Preparing the batter the night before and baking fresh in the morning is also a great option.
What if my batter is too thick or too runny?
If too thick, add a tablespoon or two of milk or water to loosen it slightly. If too runny, add a tablespoon of flour at a time until it reaches a thick but scoopable consistency.
These low sugar pumpkin zucchini bars strike a perfect balance between healthful ingredients and comforting flavors, making them a versatile addition to your baking repertoire. Whether you enjoy them as a wholesome snack, a quick breakfast, or a lunchbox treat, these bars provide nourishing satisfaction with minimal added sugar.
