With only six ingredients, showy Strawberry Pavlova will wow your family. Plus, this fruit dessert only take 15 minutes to prep!
Position rack in middle of oven and preheat to 350ºF. Line a baking sheet with parchment. Trace an 8-inch circle on parchment, then flip parchment over.
In a perfectly clean, dry bowl with clean, dry beaters, whip egg whites on medium speed until foamy, about 1 1/2 minutes. Increase speed to high; continue to whip, stopping and adding sugar in spoonfuls and scraping down sides of bowl, until mixture is stiff and glossy, about 5 minutes. Fold in vinegar and vanilla.
Use a spatula to spread meringue into an 8-inch circle on parchment, making a shallow well about 5 inches in diameter in center. Reduce oven temperature to 200°F. Bake until outside of meringue is lightly crisp and just barely browned but inside is still soft, 1 hour 30 minutes to 1 hour 45 minutes. Turn off oven, crack open door (use a wooden spoon if it won't stay open) and let meringue cool completely inside oven, about 2 hours.
Just before serving, whip cream until it holds stiff peaks. Spread on top of meringue. Top with berries and serve immediately.
