Tips for Making Gooey Chocolate Chip Toffee Bars
- Weigh your ingredients. I don’t give you much of a choice, as I don’t include volume measurements, but it’s worth re-stating regardless.
- Don’t overbake. These bars will be perfectly gooey if baked properly. You can eve start checking for doneness a few minutes sooner than stated, if your oven tends to bake fast or run hot.
- Use unsalted butter, to prevent overly salty cookie bars.
- Use one large egg. Use one large egg. Don’t use an egg that’s too large or too small, as this will impact the texture of your bars greatly. A large egg in the US is about 70 grams in shell. Bring the egg to room temperature before using.

Notes
Chocolate Chip Toffee Bars will keep well inside an airtight container for about 3 days. Store at room temperature.
I haven’t tried these bars with any substitutions, but other types of nuts and varieties of chocolate will work too – just note that this will change the overall flavor, so some experimentation may be needed.
