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 degrees 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.
