Separate your egg whites from the yolks straight from the fridge. Put the egg whites in a bowl and allow them to come to room temperature. (You can dispose of, or use your egg yolks in another recipe)
Preheat the oven to 300 degrees Fahrenheit.
Draw an 8inch circle on parchment paper. (Use the bottom of an 8inch cake pan to trace). Flip the parchment over and place it on a baking sheet so you can see the circle but the pencil doesn't get on the pavlova.
Beat the egg whites in a large bowl of a stand mixer or with a hand mixer over medium speed for 3-5 minutes until soft peaks form.
Continue mixing over medium speed, adding in your sugar 1 tablespoon at a time. Add the sugar in every 30 seconds to 1 minute, allowing the sugar to mostly dissolve in between each addition.
Once the sugar is all added, continue mixing the egg whites for 5-15 minutes until the sugar is dissolved and the egg whites are thick, stiff and glossy.
Add in the vanilla extract, lemon juice, and cornstarch and fold them into the egg whites with a rubber spatula.
Scoop the mixture onto the prepared parchment paper inside the circle.
Working from the middle to the edges, slightly build up the edges, leaving a slight indent in the middle.
Place the pan in the oven and lower the oven temperature to 225 degrees.
Bake the pavlova in the oven for 1 hour until the edges are set and the bottom of the pavlova starts to peel away from the parchment.
Turn off the oven and open the door a crack and prop it open with a wooden spoon. Allow pavlova to cool in the oven for a few hours.
Transfer to a cooling rack to cool completely if not already cooled.
Wrap the pavlova carefully in plastic wrap until you're ready to serve for up to 2 days.
When ready to serve top pavlova with whipped cream and fresh fruit and serve.
