Cake Flour:You can make your own cake flour by measuring 1½ cups of all-purpose flour, removing 3 tablespoons, and adding 3 tablespoons of cornstarch. Mix and sift well before using.
In a pinch, you can use all-purpose flour in place of the cake flour.
You can use salted butter instead of unsalted; simply omit the salt.
For a richer flavor, you can use dark brown sugar instead of light.
Feel free to use your favorite kind of chocolate chips, such as milk, semisweet, or dark. You could even use caramel baking chips!
You can stuff these cookies with a tablespoon of frozen nut butter or Nutella instead of caramels.
Make sure the caramels are completely covered with cookie dough. If not, the caramel will ooze out during baking.
Bake these cookies on parchment paper to prevent a sticky mess in the event that some caramel does ooze out.
These cookies are best enjoyed warm from the oven. If eaten at room temperature, the caramel will be firmer and more chewy. Rewarm for 15 seconds in the microwave or a few minutes in a 350°F oven.
