Step 1

Preheat oven to 350° Fahrenheit. Grease a large 9x13" baking dish with vegan butter. Tear brioche buns into pieces and place them in the baking dish.

Step 2

Combine soy milk, sugar, and the rest of the vegan butter in a microwave-safe dish and microwave about 30 seconds to melt the butter. Mix in the cinnamon and stir until the sugar is dissolved, then pour mixture over the bread pieces.

Step 3

Use a spoon to press bread down to absorb the liquid. Keep pressing all over until all of the bread is moistened. Spread blueberries over the top.

Step 4

Bake for 15 minutes, uncovered. Allow to cool 5 minutes before serving. Serve with maple syrup or vegan whipped cream. You can optionally top it off with a dusting of powdered sugar.
