Add the yeast, warm water, and sugar to a small bowl and let sit for 10 minutes or until yeast is foamy.
Add the flour, salt, and cinnamon to the bowl of a stand mixer. Make a well in the center of the flour and pour the yeast into the well.
Turn mixer, fitted with the paddle attachment, to low and begin mixing. Crack in the eggs one at a time, making sure each is incorporated before adding the next.
With the mixer on low, slowly stir in the melted butter. Increase speed to medium and beat for 1 minute or until everything is well combined. Batter will be thicker than a normal waffle batter, but much wetter than a traditional yeast dough.
Place the mixing bowl in a warm spot and cover. Let rise 45 minutes or until doubled. Gently fold in the sugar pearls and let rest for 15 more minutes.
Heat your waffle iron (mine only has one heat setting, if yours has more than one setting start at a medium heat and experiment) and spoon about 1/4 cup of batter into the center of your waffle iron. Close and cook for about 3 minutes or until golden brown and crisp. Use a fork to remove the waffles from the iron. Be careful of the melted sugar as it's very hot and will burn you if you touch it.
Top waffles with Nutella and strawberries or just eat them as is.
