Combine all ingredients and scoop the sticky batter onto a greased flan pan. Spread dough evenly with a spatula. Bake at (375°F) = (190°C) degrees for 15-20 minutes or until golden brown. Invert on cake platter after ten minutes. Cool cake before adding fruit and glaze.
Combine one cup of mashed peaches with the water and sugar in a medium saucepan and bring to a boil. Let the glaze simmer until clear. Remove from stove and stir in the butter. Let cool before assembling the fruit on cake and then scoop the glaze carefully over the sliced peaches. Serve with freshly whipped cream.
