Frequently Asked Questions
- → Why did my bars turn out too hard?
Make sure not to bake them too long. About 18 minutes is just right. They should be set in the middle but still soft when taken out. They'll firm up as they cool.
- → Can I leave out almond extract?
You can! Swap it with vanilla extract or skip it completely. Almond brings extra flavor, but it's not required.
- → Why isn’t my frosting smooth?
Start by beating your butter until creamy, then mix in powdered sugar slowly. Adding cream gradually helps get it smooth too.
- → Can I prepare these ahead of time?
Yep, they stay fresh at room temp for 3-4 days. Hold off on sprinkles until serving to avoid colors running.
- → What’s the trick for neat slices?
Make sure the bars cool totally first. Use parchment to lift them out, then cut with a sharp knife and clean it off between cuts.
