Notes
FAQ
How do I keep my brownies from drying out?
The key to irresistibly moist brownies is not overbaking them. Keep an eye on the oven and perform a toothpick test towards the end of baking. If it comes out with a few moist crumbs, they’re perfect!
Does it matter what chocolate I use?
Nope! Not at all. Mix in different textures and flavors. Combine smooth chocolates like Milky Ways with crunchy options like Kit Kats or even throw in some M&Ms for a bit of color. Feel free to get creative and use any kind of candy — candy corn included!
How do I keep the brownies fresh?
Store any leftover brownies in an airtight container at room temperature to keep them moist and chewy. They’ll last like this for several days — if they don’t get eaten first!
Are these brownies allergy-friendly?
Always check the candy for any allergens, especially when serving to other children. It’s crucial to be mindful of nuts, dairy, and gluten.
Are the brownies healthy?
These are not on the healthy side. While these brownies are a tasty treat, they’re also rich in sugar. It’s a good idea to manage portions, especially for little ones, to keep the sugar rush in check. You might be able to swap out ingredients to make them healthier, though!
