Substitutions & Additions
If you want to mix things up a bit, here are some fun ideas:
- Try using crunchy peanut butter for added texture.
- Swap half the chocolate chips for butterscotch chips for a different flavor profile.
- Add a handful of chopped nuts for an extra crunch.
- Mix in some dried fruits like cranberries or raisins for a fruity twist.
Tips for Success
Here are a few tips to ensure your Peanut Butter Lunch Lady Cookie Bars turn out perfectly:
- Make sure your butter is softened, not melted, for the best texture.
- Don’t overmix the batter once you add the dry ingredients; it can make the bars tough.
- If you want to prep ahead, you can mix the dry ingredients in advance and store them until you’re ready to bake.
How to Store Peanut Butter Lunch Lady Cookie Bars
These bars are best stored in an airtight container at room temperature. They should stay fresh for about a week, but I doubt they’ll last that long! You can also freeze them for up to three months. Just make sure to wrap them well.
FAQs
- Can I use natural peanut butter? Yes, but the texture may be a bit different since natural peanut butter can be oilier.
- Can I make these bars gluten-free? Absolutely! Just substitute the all-purpose flour with a gluten-free baking blend.
- How do I know when they are done baking? The edges should be golden brown, and a toothpick inserted in the center should come out clean.
