Prepare your baking sheet by lining it with parchment paper. I used a 21.5 x 14.5 size. Now trace about 12 (3 1/2 inch circles onto the parchment paper. Then flip it over and set it aside.
In the bowl of a stand mixer add 5 room temperature egg whites, 1/8 tsp cream of tartar and a pinch of salt. whisk on high speed until soft peaks form.
Now slowly add 1 1/3 cup granulated sugar. Once you see stiff peaks form (about 10 minutes) 1 1/2 tsp cornstarch and 2 tsp vanilla. Beat just until incorporated.
Now place a 1E piping tip into a disposable pastry bag and snip off the end. Begin piping the meringue in a circular motion starting from the center. Then you’ll want to pipe out a border on the top.
Bake the pavlovas at 225 degrees Fahrenheit for 1 hour and 30 mins on the conventional setting. Then turn the oven off and let the Pavlova sit in the oven for another 30 minutes.
For the ganache- pour 1/4 cup hot heavy over 1/2 cup of semisweet chocolate chips. Let it sit for a minute so and mix until smooth.
Now add the ganache to a piping bag and drizzle it inside each pavlova. You want to coat the entire bottom. I like to spread it around with a small spatula. Now sprinkle some chopped toasted pecans on top of the ganache.
For the cream topping- Combine 1 1/4 cup of cold heavy whipping cream with 1 tbsp granulated sugar and 1/2 tsp vanilla. Beat on high speed using an electric mixer until stiff peaks form.
Now place the whipped cream into a piping bag using the piping tip of your choice. I used a 1M piping tip.
Pipe the cream onto each pavlova and top with some berries. Serve immediately.
