@BoreOfWhabylon I see you have math’s now. Mine is very similar. The main difference is there is no egg in mine.
1 cup self-rising flour
1 cup white sugar
1 cup milk (use full fat for best result)
½ cup butter (in US that’s one stick)
1 teaspoon vanilla extract
1/2 teaspoon cinnamon
1/2 teaspoon nutmeg
1 29 oz. can of sliced peaches drained or 4 cups of fresh peaches sliced
Preheat oven to 350 degrees F (175 C). Melt butter and pour into 9x13 in. baking pan. In a separate bowl, stir together flour, sugar, milk, and spices until well-combined and pour over butter in the pan. Spread peaches over batter; do not stir. Bake 40-45 minutes until crust is golden brown. Let cool about 10 minutes. Serve warm with vanilla ice cream.
A variation: replace some of the milk with juice or syrup the peaches are canned in, but not more than ¼ cup. Also if using fresh peaches, I use ¼ cup of the sugar to mix with them and let them sit for a few minutes, and then use the remaining ¾ cup of sugar in the batter.
