UPDATED Mixed Berry Flapjacks - Calorie Count

So I really like this recipe link here but the guilty feelings when I eat half of what i've made have got too much. 

I thought I better look at how many calories are in this lovely mixture.

Ingredients                                                       Calories               Fat

225gm Butter                                                      1,688                  187g
225gm Light Brown Demerara Sugar                 898                     1g
65gm Golden Syrup                                            211                     0g
10gm Honey                                                        30                      0g
275gm Oats                                                         823                    32g       

10gm Freeze Dried Strawberries                         31                      1g
10gm Freeze Dried Raspberries                          33                      1g
10gm Freeze Dried Blueberries                           30                      0.5g
                                                                     

So calories in the whole thing are 3,744 and fat of 223.5g which is a bit scary, but only if you eat it all in one go!

So if we have 20 slices they will be 187 calories with a fat content of 11g

A standard 51g mars bar has 231 calories with a fat content of 8.6g

The total recipe is 830g divided by the twenty slices which are 41g each.
