Method
Prepare the Meringue
Preheat your oven to 250°F (120°C) and line two baking sheets with parchment paper.
In a clean mixing bowl, beat the egg whites on medium speed until foamy, then add the cream of tartar.
Gradually add granulated sugar while continuing to beat until stiff peaks form.
Gently fold in the cornstarch and vanilla extract.
Bake the Meringue
Divide the meringue mixture into two circles on the baking sheets, smoothing out the tops.
Bake for about 1.5 hours, or until the meringues are dry and crisp.
Turn off the oven and let them cool inside for an hour before removing.
Prepare the Chocolate Filling
While the meringue cools, melt the chopped milk chocolate in a heatproof bowl set over simmering water.
Stir until smooth, then remove from heat and let it cool slightly.
Whip the Cream
In another bowl, whip the heavy cream and powdered sugar until soft peaks form.
Gently fold in the cooled melted chocolate until well combined.
Assemble the Cake
Once the meringue layers are cool, place one layer on a serving plate.
Spread half of the chocolate cream mixture over the meringue.
Top with the second meringue layer and spread the remaining chocolate cream on top.
Serve
Garnish with fresh berries if desired.
Slice and serve chilled for a refreshing treat!
Notes
You can substitute the milk chocolate with dark chocolate or white chocolate for a different flavor profile. Add espresso powder to the chocolate mixture for a mocha flavor, or incorporate a layer of fruit. Store leftovers in the refrigerator, but note that the meringue may lose its crispness over time.
