    This recipe did not work at all. As others said it sunk in the middle. The mixture tasted eggy and the buttercream was like it had split. Yeuk!

        Followed the recipe to the t and it did not come out like the photo. The flavor was great however the cake did not rise and the frosting looks like goop. Do not recommend.

            Made a cake for Xmas eve and added cream cheese to the buttercream frosting and it's beyond delicious. Fell in love with the easy recipe and decide to make this as cupcakes as well. Bravo for a brilliant recipe 👏👏👏

                    Just the fix I need for my sweet tooth! I added half butter, half cream cheese for the icing to boost up the fat a bit more. The coffee and walnut combo are marvelous!

                    Just made this this as part of VE day celebrations and it was lovely. Much lighter and moist than I expected ! And my husband loved it he is not on a diet but is a diabetic and always trying to get him to eat less sugar and other carbs so another bonus, will definitely make it again.

                          Nice flavor but VERY greasy. Obvious with the amount of butter but next time I make I might try less butter or more almond flour

                            It's delicious but I had to bake it about 15 minutes longer then the directions said. The cake is very moist! Also my cakes were only about 1/2" high...didnt look like the picture above. But I will make this again!! My whole family loved it!

                            Looks really good. But the high amount of fat for one slice seems a bit off. Eggs have like 5-6 grams each and unsalted butter has like 11 grams per serving

                              Well it tasted good but unfortunately it wasn’t done. I failed somewhere. Will try again at another time 😀

                                Ah, thats such a shame but i'm glad you liked the taste at least! Cakes are very sensitive to different ovens and can vary alot - it may just need a little longer. It should also firm up quite a lot whilst cooling.
