Practical tips for a better bake
- Press the crust firmly into the pan so it holds together when you cut the bars.
- Use instant coffee granules for strong flavor; adjust to taste if you prefer milder coffee.
- Let the bars cool completely before slicing to get clean edges.
- If the top browns too quickly, cover loosely with foil for the last 10 minutes of baking.

Frequently asked questions
Q: Can I use brewed coffee instead of instant coffee granules?
A: Instant coffee gives concentrated flavor without adding liquid. If you use brewed coffee, reduce other liquid or use a stronger, reduced brew, but instant is easiest.
Q: Can I make these gluten-free?
A: Yes—swap the all-purpose flour for a gluten-free flour blend and use gluten-free graham crumbs.
Q: Will the bars be too hard if I overbake?
A: Overbaking can dry them out. Bake until the center is set but not rock hard. They should be firm and slightly soft in the middle.
Q: Can I double the recipe?
A: Yes. Use a larger pan (13×9) and adjust baking time; start checking at 30 minutes and bake until set.
