Step 1Mix base together in bowl and then press into a lined mini loaf pan or tray (I used 5 x 5 inches)
Step 2Mix filling in bowl and pour onto base
Step 3Freeze until set - for approximately 20 minutes
Step 4Melt chocolate, coconut oil and espresso (if using) and set aside
Step 5Slice bars and dip into the melted chocolate - you can pour the chocolate on to the caramel once it's set and then slice but I find it easier this way
Step 6Eat! And what you don't eat store in an air-tight container in the fridge. Mixture can also be frozen for treats at a later date.
