Somewhere over the rainbow
This is our favourite. How on earth do you get a rainbow heart inside a cake?! Cake blogger extraordinaire Amanda Rettke creates these incredible "surprise inside" cakes for her blog, I Am Baker. If you fancy a challenge, try her awesome recipe – and let us know how you get on!
What's better than a surprise birthday party? A surprise number birthday cake, that's what. Try this recipe from food blogger Hungry Happenings – perfect for little ones, not so good if you want to keep your age a secret.
Just be careful what you say about this cake in the comments, otherwise this might happen.
A work of art
If you’re a culture vulture, turn a classic Battenburg into this Piet Mondrian-inspired surprise cake. Created by food artist Caitlin Freeman at the Blue Bottle Cafe in the San Francisco Museum of Modern Art, this edible masterpiece is best exhibited on a plate. We like this version of the recipe from the Art Fund, too.
Join the dots
This surprise-inside dotty cake really hits the spot (sorry, we had to), as food blogger In Katrina's Kitchen makes one of Amanda Rettkea's creations. There's a bit of a cheat here too, as you roll up balls of shop-bought cake and drop them into packet-mix cake batter to make the dots. Easy!
