Ingredients You’ll Need
Getting started with Butterscotch Zucchini Bars couldn’t be easier. The ingredients are straightforward yet thoughtfully chosen to create the perfect balance of sweetness, texture, and color. Each component plays a crucial role, whether it’s binding the batter, adding richness, or delivering that signature butterscotch goodness.
- Butter (1 cup, room temperature): Provides richness and helps create that tender crumb everyone loves.
- Brown sugar (1 3/4 cup, packed): Adds deep sweetness and moisture for a luscious taste.
- Eggs (2 large, room temperature): Bind the ingredients together and contribute to a soft, moist texture.
- Vanilla extract (1 teaspoon): Enhances the flavors with warm, sweet notes that complement butterscotch.
- All-purpose flour (2 cups): The foundation providing structure while keeping the bars fluffy yet sturdy.
- Baking powder (1 teaspoon): Helps the bars rise beautifully without being cakey.
- Salt (1/4 teaspoon): Balances the sweetness, bringing out all the flavors.
- Finely grated and drained zucchini (1 1/2 cups): Adds moisture and a tender bite without a strong veggie flavor.
- Butterscotch morsels (1 1/2 cups): The star of the show, delivering melty pockets of caramel-like sweetness in every bite.
How to Make Butterscotch Zucchini Bars
Step 1: Prepare Your Pan and Oven
Start by preheating your oven to 350°F and preparing a 9×13-inch pan with non-stick spray or by greasing and flouring it. Proper prep makes sure those bars come out perfectly without sticking, ready to wow anyone who tastes them.
Step 2: Cream Butter and Brown Sugar
In a large bowl, use a hand-held mixer to cream together the softened butter and brown sugar until the mixture becomes lighter and fluffy. This step is essential for creating a smooth base that will give your bars their lovely texture and depth of flavor.
Step 3: Add Eggs and Vanilla
Next, add the eggs one at a time along with the vanilla extract. Mixing until everything is fully combined helps achieve that silky batter that promises moist, delicious bars each time. Don’t forget to scrape down the bowl now and then to keep everything evenly mixed.
Step 4: Combine Dry Ingredients
Mix together the flour, baking powder, and salt separately, then add them to your wet ingredients. Blend on medium-low speed until just incorporated to avoid overmixing and ensure tender bars rather than tough ones.
Step 5: Fold in Zucchini and Butterscotch Morsels
Carefully stir in the grated and drained zucchini; the batter might look a bit runny—that’s perfect! If it seems dry, just let it sit for about five minutes to hydrate fully. Now fold in 1 cup of the butterscotch morsels for hidden pockets of sweetness, saving the rest for topping.
Step 6: Bake Until Golden
Pour the batter into your prepared pan and sprinkle the remaining butterscotch morsels evenly over the top. Bake for 40 minutes, then check doneness with a toothpick. You want a few moist crumbs attached but no wet batter. The top should be a rich golden brown—this signals those glorious Butterscotch Zucchini Bars are ready to cool and be devoured.
How to Serve Butterscotch Zucchini Bars

Garnishes
These bars are lovely on their own, but you can elevate them with a dusting of powdered sugar or a drizzle of caramel sauce for added sweetness and visual appeal. A sprinkle of chopped nuts like pecans or walnuts can add delightful crunch and nutty contrast too.
Side Dishes
Serve Butterscotch Zucchini Bars alongside a scoop of vanilla ice cream or a dollop of whipped cream for an indulgent dessert experience. For a cozy afternoon snack, pair them with a hot cup of coffee or chai tea—a match made in heaven.
Creative Ways to Present
Cut these bars into small squares and serve them on a platter at your next party for easy grab-and-go enjoyment. You can also layer pieces in a dessert parfait with yogurt and fresh berries for a visually stunning twist that still keeps that iconic butterscotch flavor front and center.
Make Ahead and Storage
Storing Leftovers
Keep your leftover Butterscotch Zucchini Bars fresh by storing them in an airtight container at room temperature for up to three days. This keeps them moist and flavorful, almost as good as fresh from the oven.
Freezing
If you want to make these ahead of time or save some for later, freeze the bars tightly wrapped in plastic wrap and foil for up to three months. Thaw overnight in the fridge for a soft, melt-in-your-mouth treat any time you desire.
Reheating
Warm your bars in the microwave for about 15-20 seconds or pop them in a preheated oven at 300°F for 5-7 minutes for that fresh-baked feel. Reheating makes the butterscotch morsels even melty and irresistible.
FAQs
Can I use a different type of squash instead of zucchini?
Absolutely! Yellow squash can be a great substitute if you want a milder flavor, but zucchini is preferred because of its moisture content and subtle taste that won’t overpower the butterscotch.
Do I need to peel the zucchini before grating?
No need to peel it; the skin adds a lovely green fleck and nutrients, plus it softens nicely during baking. Just make sure to grate it finely and drain any excess moisture to avoid sogginess.
Can I omit the butterscotch morsels?
You could, but the butterscotch morsels are key to the flavor profile of these bars. If you want to switch things up, consider white chocolate chips or dark chocolate chips for a different twist.
How do I know when the bars are fully baked?
Insert a toothpick in the center; it should come out with a few moist crumbs but no wet batter. The top will be golden and slightly darkened at the edges—this indicates perfect doneness.
Are these bars suitable for freezing and thawing?
Yes, they freeze beautifully! Just wrap well to maintain freshness and thaw in the fridge before serving. Reheat slightly for that freshly baked taste and texture.
