Heat oven to 350°F. Line a 9-inch cake pan (not springform) with parchment paper and generously butter the surface.
02 -
Layer peach wedges in a concentric pattern over the parchment, starting from the center. Sprinkle with 1/4 teaspoon ground cinnamon.
03 -
Combine 1/2 cup sugar and 1/4 cup water in a saucepan. Stir once to combine, then cook over medium-high heat without stirring until light amber, about 10–15 minutes. Remove from heat, carefully add 1 tablespoon bourbon, and immediately pour the caramel evenly over the peaches.
04 -
Beat the butter and 3/4 cup sugar with an electric mixer until pale and fluffy, about 3 minutes. Add eggs one at a time, beating well after each addition. Mix in vanilla extract and 2 tablespoons bourbon.
05 -
In a separate bowl, whisk together all-purpose flour, almond flour, baking powder, and the remaining 1/4 teaspoon cinnamon.
06 -
Gradually beat the dry mixture into the wet ingredients until just combined, avoiding overmixing.
07 -
Spoon the batter over the peaches in the prepared pan and gently smooth the surface with an offset spatula.
08 -
Bake on the center rack for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
09 -
Allow to cool in the pan for 15–30 minutes. Run a knife around the edge and invert onto a serving plate. Remove parchment and let cool before slicing.
