Textural tip: Chop or pulse your chocolate into differently sized bits for a great textural variety. Be sure to include the chocolate "dust" as well.
Freezing Tip: Once you make your cookie dough, you can portion and freeze them for later use. Scoop your cookie dough into portions onto a baking sheet and freeze them until solid and then store them in an airtight bag or container.
Temperature Tip: Be sure you're baking at 325F. Any higher and the toffee chips will melt and leak out before the cookie dough has time to set and it will end up making a mess.
Baking Tip: If baking from frozen dough, let your dough thaw in the fridge until soft. If baking after being chilled in the fridge set your portioned cookie dough onto a baking tray on the counter for 10-15 minutes then press down and bake 10 min at 325. turn off oven, let cookies rest for another 3-5 minutes in the closed but turned off oven. Keep an eye on them and don't let them get too browned.
Cookie Shape Tip: If your cookies spread out too much or have an odd shape once baked, you can reshape them by using a spoon or silicone spatula to gently push in the edges to get them back into rounds. You should do this within 30-60 seconds after you've baked them before they set up and cool.
