Gaufres a la glace

If you can, prepare your batter the evening before for best flavor. If enjoying same day, then begin 1 1/2 hours before you want to cook your waffles. Start by pouring the warm water, yeast, and sugar into a very large bowl. Do not stir. Let the mixture rest for 5 minutes, or until it's frothy.

Add the warm milk, melted butter, honey, vanilla extract, and kosher salt; whisk to combine. Then add in the all-purpose flour and whisk until smooth. Cover the bowl tightly with plastic wrap. Let the batter rest in a cool place on your counter overnight, or for at least 1 hour.

After your batter has rested, it should have risen in height and slightly bubbled on the surface. In a small bowl, beat the egg and baking soda together. Add this into the waffle batter and whisk to combine.

Heat your waffle iron and brush with oil or melted butter. Use a half cup measuring tool to scoop out 1/2 a cup of the waffle batter onto the iron. If your waffle iron has a timer for notifying you when the waffles are ready (usually about 3 to 4 minutes for most machines), let the waffles cook a little bit longer (like 5 to 6 minutes), or until they're slightly browned and crispy on the outside.

Place the cooked waffles on a metal wire rack in the oven with the hold setting on to keep the waffles warm while you finish cooking all of them. Dust the finished waffles with powdered sugar and place a scoop of your favorite ice cream right in the center of each.
