Preheat oven to 400 degrees F. Spray a baking sheet with cooking spray.
In a mixing bowl, whisk together flour, baking powder, sugar, salt and baking soda. Add buttermilk and eggs and beat on low speed 30 seconds until combined, then beat 1 minute on high speed. Dough will be sticky and will have the appearance of frosting.
With wet hands, scoop out 6 to 8 even portions of dough and place them on prepared baking sheet, mounding the dough slightly into a bun shape. Re-wet fingers and smooth the tops and sides of each bun. If desired, sprinkle with sesame seeds.
Bake in preheated oven for 10-15 minutes or until golden brown. Allow to cool. Split to serve with hamburgers.
Cook’s note: The dough is sticky, so do keep a bowl of water handy to wet your hands before scooping out the dough for each bun and smoothing out the tops.
