Upside-Down Peach Cake

This upside-down peach cake pairs the natural sweetness of ripe, summer peaches with the cozy warmth of cinnamon sugar. Thinly sliced peaches are layered over a dusting of cinnamon sugar, then topped with a cake batter flavored with vanilla and lemon zest. As the baked and cooled cake is flipped over, a spiral of cinnamon-scented caramelized peaches is revealed. Each bite of this soft and tender cake is a marriage of buttery richness and sweet, comforting peaches.
Peaches are one of my favorite summer fruits. You can’t beat the joy of eating a perfectly ripe peach and I love coming up with recipes that celebrate them in all of their goodness, like this cake!
I didn’t want to make just any kind of cake. I wanted to make one that really made these summer peaches shine! I felt an upside-down cake would be perfect for doing that.
