How do I look?

Our Rocky Road Cake is made with an indulgent marbled chocolate sponge, held together and topped off with a generous amount of chocolate buttercream and loaded with gooey marshmallows and milk chocolate and white crispy pearls.

STORAGE - Please store me in an air-tight container in a cosy spot - I don't like being kept in the fridge. Can be frozen for up to 6 months.

How do I arrive?

Our sponge cakes are packaged in secure and robust packaging. The inner box is wrapped around the cake to securely hold it in place so the sides and top do not get damaged in transit. The box also includes a handy cutting guide! It is then put in a strong cardboard outer box for extra protection so it will arrive to you safely.

    a wonderful product that can be for any occasion. For birthdays, anniversaries, moving home, just because. Ive ordered some wrapped which come in a fab cake wrapping paper also the hot chocolate & coffee added on selections. You also add a gift card from a great selection. The 14 slice cake was fab did cause a couple of friendly arguments of who wants what flavour. The mini's are great as a takeaway cake in its little box. The rocky road went down great as a birthday surprise and a moving home gift. I really recommend Sponge to everyone and will definitely be back and tell all my friends.

    The Rocky Road cake was delicious - the cake is a good size (very deep) and the sponge to buttercream ratio was spot on. The image on the website is true to life. We have since ordered another cake as it was just so more-ish :-) Thank you.
