Add the wet and dry ingredients together and mix using an electric mixer fitted with dough hooks. Mix on medium-high speed for at least 5 minutes to ensure a smoother, more cohesive dough. About halfway through, scrape down the sides and bottom of the bowl with a silicone spatula to make sure all flour is incorporated.
You can mix using a sturdy wooden spoon or even your hands if necessary, though this may result in less smooth tops.Note: The dough will be fairly sticky - that’s normal! Resist the urge to add extra flour to the dough.
Dust the working surface with gluten-free flour and turn the dough onto it. Shape the dough into a ball, dusting it as you go to prevent sticking.
Divide the dough ball into 16 parts using a bench scraper as you would for scones (see picture). You can use a scale or simply eyeball the parts for this step.
Slightly wet or oil your hands before shaping the buns to prevent sticking. Shape each dough part into a small, tight ball and place them onto a baking sheet lined with parchment paper or a baking mat.
Cover the buns and let them proof at room temperature for about 1-1.5 hours. The buns will puff up but won't double in size. To speed up the process, place the buns uncovered into the oven at 120°F/50°C (not higher).
Once the buns are done rising, take them out of the oven (if that's where they were) and start preheating it to 350°F/175°C. In the meantime, prepare the egg wash by whisking an egg in a small bowl.Gently brush the buns with an egg wash and top with sesame seeds. For the vegan version, use oil instead of the egg.
Once the oven is ready, bake the buns for 30 minutes, then carefully remove them from the oven and let them sit on the baking sheet for 10 minutes, then you can transfer them to a cooling rack. Enjoy!
Notes
Expert Tips:
Don't open the oven during baking to prevent the buns from collapsing.
Make sure the buns are spaced out and aren't touching to ensure a thorough bake-through, like you would with these gluten-free sourdough hot cross buns.
