Everybody loves grandma’s old-fashioned banana pudding with cooked custard. I flipped mine upside down and put the meringue on the bottom for this fun pavlova. Make ahead and WoW your holiday guests.
Preheat oven to 200 degrees. Place parchment paper on a large sheet pan or 2 smaller ones.
Meringue
Whip the egg whites with salt and cream of tartar until peaks are firm and glossy.
Continue mixing, slowly adding sugar. Add cornstarch with extracts and beat for 10 seconds.
Fold in 2 cups of wafer crumbles. Divide in half and spread each onto the baking pan(s).
Leave a shallow well (1½-inch rim) in the center. Scatter with more chopped wafers, saving a bit for garnish.
Bake 1½ hours. Turn oven off and let sit several hours or overnight.
Custard
For custard, combine ingredients through vanilla and heat over double boiler until thickened, whisking as it cooks to keep a creamy consistency. Chill.
Topping
Place meringue on serving plate. Top with sliced bananas, custard and whipped cream. Dust with remaining wafer crumbs.
Notes
*To make caster sugar, put granulated sugar into food processor or blender and pulse into finer granules (but not powdered).Best not to make the meringue on high humidity days. Can be wrapped in plastic then foil and frozen up to a month.
