Preheat oven to0 350 degrees F. Generously grease a 9 by 13 baking pan with butter or coconut oil. Set aside.
In a large mixing bowl, whisk together eggs, cream, confectioners sweetener, vanilla stevia, salt, and maple extract. Once combined, pour in cubed bread and toss together to evenly coat bread.
Pour this into your baking dish. Place cold slices of butter all over the top of the bread pudding. If using optional strawberries, randomly insert them between bread. Drizzle over the liquid Allulose if using.
Bake 30-35 minutes until it's set but still jiggly and puffed up. Enjoy warm out of the oven or cool, refrigerate and serve chilled!
