For the puffs:
Softened unsalted butter, for greasing the pan
tablespoons butter, melted
large eggs, at room temperature
cup whole milk
For the sugar coating:
teaspoon ground cinnamon
tablespoons butter, melted.
1. Preheat the oven to 400 degrees. Liberally grease a nonstick popover pan, or a muffin pan with 1/2-cup indentations, with softened butter. 2. For the puffs, put the 2 tablespoons melted butter, eggs, milk, salt and sugar in a blender and whiz for a few seconds. 3. Add the flour and whiz for 5 to 8 seconds, just until smooth. 4. Divide the batter among 9 greased molds, filling each 1/2 to 2/3 full. 5. Bake for 35 minutes, until the puffs are deep brown. 6. Remove from the oven, wait a few minutes until cool enough to handle, then remove the puffs from the pans. You may need a small knife to help pry them out. 7. Mix the sugar and cinnamon in a medium bowl. Thoroughly brush each puff all over with melted butter, then dredge in sugar and cinnamon mixture to coat completely. Let cool on a baking rack. Makes 9 puffs.
