No1 son and I tried this little number last week and it went down a treat!
We were using up the bars from the Easter Eggs 
The cake was just coming out of the oven as we finished our evening meal so I served it without the topping, warm with Ice cream, it really was delicious.
Next evening we had the leftovers cold – again with no topping.
Well worth a try!
MMMM! Looks good!
