This almond and plum sheet cake from Romy London takes inspiration from classic German fruit cakes that pair soft sponge with seasonal fruit and a crumbly topping. Plums work especially well here because their sharpness balances the sweetness of the cake. As they bake, they soften into the sponge and create pockets of jammy fruit throughout each slice.
The cake base combines oats and almond flour, which give it a slightly nutty texture without making it too heavy. Cinnamon, nutmeg, and lemon zest lift the flavor and keep it tasting fresh. On top, the crumble adds crunch and contrast. Coconut oil helps the topping crisp up in the oven, while flaked almonds give extra texture. The whole cake bakes in one tray, so it’s easy to slice and share once cooled.
