The Best Zucchini Bars Tips
These are decadent, luscious, and easy-to-make dessert bars. Zucchini is so easy to shred and prepare for this simple zucchini bar recipe. Add in nuts or chocolate chips even to make it a variety of zucchini bars!
- Zucchini: When shredding your zucchini, do it finely, especially if you are worried about kids figuring out what’s hiding in their dessert. The smaller, the easier it is to hide. You can also peel the zucchini, but it isn’t necessary. Do not to squeeze out any extra liquid. You want the moisture to create the best bars ever.
- Pecans: If you do not like pecans, you can leave them out or use walnuts.
How To Brown Butter
Don’t be scared by browning butter. It is super simple and foolproof if you follow these tips. To get the best-browned butter, make sure to use unsalted butter.
- Use a light-colored pan: You want to be able to see the brown bits form at the bottom of the pan. Using a dark-colored pan will prevent you from seeing when those have formed, and this is a key clue to when your butter is done. Those dark specks are the toasted milk solids that bring the flavor, so don’t leave them behind.
- Don’t Stop Stirring: This will make sure your butter cooks evenly and will help prevent it from going from brown to burnt too fast, which can happen.
- Cut the butter into pieces: Again, you want it to cook evenly, and cutting it will help it do so.
- Remove from heat and pan: Once your butter has foamed, turned golden brown, and the brown specks form, you want to remove it from the heat. Transfer the butter to a different pan as well, or as in this case, add something to the pan. This will help the butter stop cooking so it doesn’t go from browned to burnt.
- Smell: It should have a buttery, nutty, rich smell as well.
Storing Leftovers
- Room Temperature: Zucchini bars with butter frosting will keep at room temperature in an airtight container for up to 3 days.
- In the Refrigerator: They will last even longer in the fridge, up to 10 days.
- In the Freezer: You can also freeze them. Refrigerate the sheet pan first, then cut them into bars and place them in freezer-safe bags. They will last about two months.
