Preheat oven to 350°F and prepare a 9x5 inch loaf pan with non-stick spray and parchment paper.
In a large bowl, whisk together gluten free baking flour, tapioca flour, sweetener, baking powder, baking soda, and salt until combined.
In a separate bowl, beat vegan butter with a handheld mixer until light and fluffy. Add eggs, almond milk, vegan yogurt, and vanilla extract, mixing until combined.
Add the wet ingredients to the dry ingredients and mix just until combined. The batter will be thick. Fold in the gluten free sprinkles.
Transfer batter to prepared loaf pan. Wet a rubber spatula and smooth batter edges towards the middle to create a dome shape.
Bake for 25 minutes, then cover the loaf with foil and bake for another 15-20 minutes or until a toothpick inserted comes out clean.
Allow the loaf to cool in the pan for 30 minutes before removing.
Stir together the glaze ingredients and drizzle over the cooled loaf. Slice and serve.
