Creating these delicious squishy, soft gluten-free hot dog buns is simple when you follow these steps:

1. Preheat the Oven: Set your oven to 375°F (190°C) and line a baking tray with parchment paper.
2. Combine Dry Ingredients: In a large mixing bowl, whisk together the gluten-free flour, sugar, instant yeast, salt, and xanthan gum.
3. Mix Wet Ingredients: In another bowl, combine the warm water, vegetable oil, apple cider vinegar, and the egg. Whisk until fully combined.
4. Combine Both Mixtures: Gradually add the wet mixture into the dry ingredients. Stir until the mixture is well combined and smooth.
5. Knead the Dough: Transfer the dough onto a lightly floured surface. Knead gently for about 3-5 minutes until the dough becomes smooth.
6. Shape the Buns: Divide the dough into equal portions (approximately 8-10). Shape each portion into an oval or hot dog-form.
7. Let it Rise: Place the shaped buns on the lined baking tray. Cover with a clean towel and let them rise in a warm spot for about 20-30 minutes.
8. Bake the Buns: Once risen, bake in the preheated oven for 20-25 minutes or until golden brown on top.
9. Cool Down: Take the buns out of the oven and let them cool for about 10 minutes on a wire rack before serving.

By following these simple steps, you’ll have delicious, squishy, soft gluten-free hot dog buns ready for your favorite fillings.
