This stunning upside-down cake is the perfect, easy dessert to showcase your bounty of summer fruit. The cake is tender and moist, with just enough of a delightful toothy texture from the incorporation of cornmeal into the batter. You’ll want to use juicy, ripe blueberries and peaches for best results; however, you could use frozen fruit in a pinch—just be sure to thaw and dry throughly. A few more tips to ensure upside-down cake success: Finish incorporating the ingredients by hand, this will prevent over-mixing your way to a tough cake. Also, aim to arrange the fruit as tightly as you can in the cake pan; fruit shrinks as it cooks and you don’t want too much unadorned cake poking through. Finally, if you want to skip the cornmeal, simply swap it 1:1 with all-purpose flour (for a total of 1 1/3 cups).
