How to Store and Reheat

Tips for Success
- Add extra M&M’s on top of the batter before baking the bars. This will give you a little extra sweetness and crunch.
- Make sure you pat the blondie batter into your prepared dish. This will make sure they cook evenly and will be easier to cut after they cool.
- Feel free to use your favorite peanut butter for this recipe. If you want to reduce the sugar, you can use sugar-free peanut butter.
- The center of your blondie bar should be chewy and moist, but not necessarily gooey. You want to make sure that the batter is cooked and not still raw in the center before removing them from the oven.
