She made me a cake.
Literal
She [topic-は] me [to-に] cake [object-を] made [for me-てくれた].
ケーキ — 'cake' — is one of countless food loanwords in Japanese. Western-style sponges, sponge-with-strawberries Christmas cakes, fluffy roll cakes, and whipped-cream-laden 生ケーキ are all called by the same word; native terms (洋菓子 'Western confectionery,' 和菓子 'Japanese confectionery') split desserts by tradition rather than form. The auxiliary ~てくれる on 作る folds in gratitude — she didn't just bake, she baked for me.
