Rainbow sprinkles add a touch of sweetness and bright, fun colour to these charming biscotti.
Preheat the oven to 350°F.
Whisk together the flour, baking powder and salt in a medium bowl and set aside. Whisk together the coconut oil and sugar in a separate large bowl. Whisk the eggs into the coconut oil mixture one at a time, and then the vanilla. Whisk the dry ingredients into the wet ingredients, and then fold in the sprinkles.
Line a baking sheet with parchment, divide the dough into 2 parts and form each part into a long rectangle, about 4 inches wide. Leave a few good inches in between the rectangles because they will spread in the oven. Sprinkle the tops with a few pinches of sea salt and bake until firm and just beginning to brown around the edges, about 25 minutes.
Remove from the oven and reduce the heat to 250°F. Use a serrated knife to cut the rectangles into 1-inch pieces and place them on the lined baking sheet cut-side down. Bake until crisp, about 20 more minutes. Transfer to a wire rack to cool completely, about 1 hour.
