Step 1

In a microwavable mug, place the chopped dates, baking soda and water.

Step 2

Place in microwave for 50 seconds until the dates are softened.

Step 3

Add the butter and stir until melted.

Step 4

Stir in the sugar, flour and egg to the mug until combined. Add in walnuts now if you like them.

Step 5

Place in the microwave for 1 minute- 1 minutes 15 seconds. When it is firm to the touch on top it is done. (This timing is based on my 1200W microwave so yours might vary)

Step 6

Drizzle caramel sauce over the sticky toffee cake and enjoy!
