In a large mixing bowl, sift together the flour, baking powder, baking soda, and kosher salt. Set this bowl aside.

Wet Ingredients

In a separate small bowl, whisk together the egg yolks, milk, melted butter, and vanilla extract until well combined. Set aside.

Melt the butter needed for assembly and set it aside. If you're making homemade whipped cream, prepare it now and chill until ready to use. In a small bowl, stir together the granulated sugar and ground cinnamon and set aside.

In a mixing bowl or the bowl of a stand mixer, whip the egg whites until soft peaks form, then gradually add the sugar. Continue beating until stiff peaks form.

Add the wet mixture to the bowl of dry ingredients and stir until just combined. Then, using a spatula, gently fold the whipped egg whites into the batter until fully incorporated without deflating the mixture.

Cook the waffles according to your waffle iron’s instructions until golden and crisp.

Once cooked, brush both sides of each waffle with the melted butter, then press each side into the cinnamon sugar mixture, coating thoroughly.

Serve warm with a generous drizzle of caramel sauce and a dollop of whipped cream on top.
