Activate the Yeast: In a small bowl, dissolve the sugar in warm plant-based milk. Add the yeast, give it a gentle stir, and let it sit for about 5-10 minutes until it becomes frothy.
Prepare the Flax Egg: In a small bowl, mix the ground flaxseed with water and let it sit for 5 minutes until it thickens to a consistency similar to that of a regular egg.
Combine Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour and salt.
Mix the Dough: In a separate large mixing bowl, combine the activated yeast mixture, flax egg, softened vegan butter, and maple syrup. Gradually add the dry ingredients, mixing until a soft dough forms.
Knead the Dough: Turn the dough onto a floured surface and knead for about 8-10 minutes or until it becomes smooth and elastic. Place the dough in a greased bowl, cover it with a kitchen towel, and let it rise in a warm place for 1-2 hours or until it doubles in size.
Shape the Dough: Punch down the risen dough and divide it into two equal parts. Shape each part into a loaf and place them into greased loaf pans.
Second Rise: Cover the pans with a kitchen towel and let the dough rise again for about 1 hour.
Preheat the Oven: Preheat your oven to 350°F (175°C).
Brush with Plant-Based Milk: Before baking, brush the tops of the loaves with plant-based milk to achieve a golden-brown finish.
Bake: Bake in the preheated oven for 25-30 minutes or until the tops are golden brown and the loaves sound hollow when tapped.
Cool and Enjoy: Allow the brioche loaves to cool in the pans for a few minutes before transferring them to a wire rack to cool completely. Slice and enjoy your Vegan Milk Brioche!
