Preheat oven to 425° and line a baking sheet with foil
peel and slice your peaches into ½" wedges
combine 24 peach wedges with 2 tbsp of peach schnapps, 2 tsp of lemon juice, and 1 tbsp sugar and set aside
slice the remaining peach wedges into 3pcs each and toss in a bowl with 3 tbsp peach schnapps, 2 tsp lemon juice and 2 tbsp sugar, let sit for 10 min
drain most of the liquid from diced peaches, place on baking sheet in single layer and roast 20-25 min until juices around the edges of the peaches turn dark and peaches look "dry"
after removing roasted peaches from the oven reduce temperature to 350° and let diced peaches cool @20 min
melt 1 stick of unsalted butter in a microwave and let cool
combine flour, baking powder, salt and set aside
whisk together ⅓ cup sugar, brown sugar, and eggs until well combined about 1 minute
slowly whisk in butter until completely incorporated
add sour cream and vanilla and combine well
add dry ingredients to wet ingredients and combine well
spray and flour a 9" springform pan and fill with ½ of the batter
top batter with cooled diced roasted peaches in an even layer
spread gently the remaining batter over peaches
with peach wedges make a circular pattern on top of cake batter (SAVE THESE JUICES IN THE BOWL)
take 1 tbsp of sugar and ⅛ tsp almond extract and with a fork combine them well (it doesn't seem like ⅛ of a tsp would be enough but I promise you it is)
sprinkle over top of cake and bake 60-65 minutes (until golden brown and a toothpick comes out clean in the center) cool 10 minutes then remove the sides of pan
add the last 1 tbsp of peach schnapps and 1 cup of powdered sugar to your peach juices from your wedges and combine (this should make a thin boozy glaze)
pour glaze around outer edge of warm cake and spread sparingly over the middle (do not let glaze pool in the middle of the cake)it is ok for the extra glaze to run off the sides of cake we want a thin layer here, we do not want our cake to get soggy from the glaze, cool completely
