FAQs

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

Yes, though the texture may be softer and less chewy.

What’s the best way to cut these cleanly?

Let them cool completely, then use a sharp knife wiped clean between cuts.

Can I substitute the sweetened condensed milk?

Not directly. It’s essential for the gooey texture, though you can experiment with homemade versions.

Are these bars overly sweet?

They are rich, but not cloying. Using dark chocolate chips can help balance the sweetness.

Can I add coconut to this recipe?

Yes, mix in up to ½ cup shredded coconut for added texture and flavor.

How do I know when they’re done baking?

The top should be golden brown and the edges slightly firm. The center may still look soft but will set as it cools.

Can I use white chocolate instead?

Yes, but it will change the flavor significantly—still delicious, just different.

Are these bars good for mailing?

Yes, they hold up well and can be packaged for gifting or shipping.

Can I make these in an 8×8-inch pan?

Yes, but halve the recipe or extend the baking time if making a thicker batch.

What drinks pair well with these bars?

Cold milk, coffee, or a dessert wine like port pair beautifully with these rich bars.
