Can I use quick oats instead of old-fashioned oats?

Yes, but the texture will be slightly different. Old-fashioned oats provide more chew and texture, while quick oats create a more uniform, softer bar.

Why are my bars falling apart when I cut them?

This usually happens when the bars haven't cooled completely or weren't pressed firmly enough before baking. Make sure to compact the dough well and let them cool for at least 2 hours.

Can I double this recipe?

Absolutely! Use a large sheet pan (18x13 inches) and increase the baking time by 5-10 minutes. Check for doneness by ensuring the edges are golden brown.

How do I know when the bars are done baking?

The edges should be golden brown and the center should feel set but still slightly soft. They'll continue to firm up as they cool.

Can I make these without eggs?

Yes! Replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) or use ¼ cup unsweetened applesauce.

What's the best way to cut clean squares?

Use a sharp knife wiped clean between cuts, or lightly spray the knife with cooking spray to prevent sticking.
