Ingredients
Wet Ingredients
- 1 cup (227g) butter, room temperature
- 1 3/4 cup (350g) brown sugar, packed
- 2 large eggs, room temperature
- 1 teaspoon vanilla extract
Dry Ingredients
- 2 cups (250g) all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon salt
Add-ins
- 1 1/2 cup finely grated and drained zucchini, packed
- 1 1/2 cups butterscotch morsels (divided)
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Prepare a 9×13 inch baking pan by spraying it with non-stick spray or using the butter and flour method to prevent sticking.
- Cream Butter and Sugar: In a large mixing bowl, combine the room temperature butter and packed brown sugar. Using a hand-held mixer, beat them together until the mixture becomes lighter in color and fluffy in texture.
- Add Eggs and Vanilla: Incorporate the eggs and vanilla extract into the creamed butter and sugar. Mix thoroughly for 1-2 minutes until fully combined, stopping to scrape down the sides of the bowl as needed to ensure even mixing.
- Combine Dry Ingredients: Add the all-purpose flour, baking powder, and salt to the wet mixture. Mix on medium-low speed until the ingredients are just combined, being careful not to overmix.
- Mix in Zucchini: Gently fold in the grated and drained zucchini on low speed. The batter should be runny; if it appears dry, let it rest for about 5 minutes to allow the zucchini to release moisture.
- Add Butterscotch Morsels: Stir in 1 cup of butterscotch morsels using a spatula to evenly distribute them throughout the batter.
- Pour Batter and Add Topping: Pour the batter into the prepared baking pan and spread it evenly. Sprinkle the remaining 1/2 cup of butterscotch morsels evenly over the top.
- Bake and Test Doneness: Place the pan in the preheated oven and bake for approximately 40 minutes. Check for doneness by inserting a toothpick in the center—it should come out with a few moist crumbs but no wet batter. The top and edges should appear dark and set.
- Cool and Serve: Allow the bars to cool completely in the pan before cutting into squares and serving.
Notes
- Make sure to finely grate and thoroughly drain the zucchini to prevent excess moisture from making the bars soggy.
- Using room temperature butter and eggs helps achieve a smooth, well-mixed batter.
- If you do not have butterscotch morsels, butterscotch chips or chopped butterscotch candy can be used instead.
- Letting the batter rest after adding zucchini allows it to absorb moisture, improving texture.
- Store leftover bars in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
