Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan or cast iron skillet with butter.
In a medium bowl, toss the sliced 4 medium peaches with 2 tbsp brown sugar, 2 tsp lemon juice, 1 tsp vanilla extract, and 1 tbsp all-purpose flour. Set aside to let the juices start to mingle.

In a large bowl, cream the softened 1/2 cup unsalted butter and 3/4 cup granulated sugar together until light and fluffy (about 2-3 minutes). Add the 1 large egg and 1 tsp vanilla extract, and mix well.

In a separate bowl, whisk together 1 1/2 cups all-purpose flour, 1 1/2 tsp baking powder, and 1 tsp salt. Add the dry mixture to the butter mixture in two additions, alternating with the 1/2 cup buttermilk. Stir until just combined — don’t overmix.

Spread the batter evenly into your prepared baking dish. Spoon the peaches and their juices evenly over the top — it’s okay if some sink in. That’s part of the charm!
Bake for 45–55 minutes, or until the top is golden brown and a toothpick inserted into the cake (not the fruit!) comes out clean. The edges will be slightly crisp, and the fruit will bubble up a bit through the top.
Let it cool for at least 20 minutes before serving. Serve warm and top with 4 scoops vanilla ice cream and 1/4 cup caramel topping.
