This Greek Yogurt Peach Upside Down Cake is a gorgeous display of fresh peaches! It is ridiculously moist with a delicious lemony flavour and best served warm out of the oven with a scoop of ice cream! If you want more of the peach flavour, add the optional diced peaches to the batter. This makes 2 cakes.
Alternately add the flour and yogurt mixtures in two parts, mixing just until combined after the addition of each. Fold in the optional diced peaches, if using.
Pour the melted butter into the bottom of the pan(s), spread to evenly coat the bottom, and evenly sprinkle with the brown sugar. Arrange the peach slices along the bottom of the pan. Divide the batter and spoon on top of the peaches, gently spreading with a spatula to evenly cover the peaches, and bake for approximately 30 minutes (or 20-25 minutes for the muffins) until golden brown and a toothpick inserted in the centre comes out clean.
Cool for 5-10 minutes before inverting onto a plate or cake stand. Serve with whipped cream or ice cream.
