Preheat oven to 350ºF (180ºC) and line a baking sheet with parchment paper.
Mix the flour, sugar, cinnamon, baking powder and salt in a large bowl until combined.
Heat honey and oil in a small saucepan over low heat until warm, but not hot.
Beat two eggs in a medium bowl, then add the honey and oil mixture and mix to combine.
Add this mixture to the dry ingredients and mix until you have a uniform, slightly wet dough. Divide into 24 equally sized pieces, and form into small spheres or ovals.
Beat the remaining egg in a small bowl. Brush the top of each broa lightly with egg, then roll in granulated or raw sugar if desired.
Place on the parchment-lined baking sheet, spaced at least an inch apart. Bake for 10-12 minutes, or until the tops are golden brown—watch closely to make sure they don't burn.
Let the broas cool, then enjoy!
