Preheat the oven to 175°C and line 2 baking sheets with parchment paper. Let the dairy-free margarine soften fully so it creams smoothly with the sugars.
In a large mixing bowl, beat the softened dairy-free margarine, granulated sugar, and brown sugar for 2 to 3 minutes until the mixture looks lighter and fluffy.
Add the egg, vanilla extract, and almond extract. Beat until fully combined, scraping down the sides of the bowl so the mixture is even.
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This helps distribute the leavening evenly through the dough.
Add the dry ingredients to the wet ingredients and mix on low speed just until no dry streaks remain. Fold in the shredded coconut and 20 grams of the holiday sprinkles until evenly distributed.
Scoop the dough into 24 equal portions, about 1 1/2 tablespoons each, and place them on the prepared baking sheets with space between each cookie. Gently flatten each mound slightly with your fingertips, then top with the remaining 10 grams of sprinkles.
Bake one sheet at a time for 10 to 12 minutes, until the edges are lightly golden and the centers look just set. Do not overbake if you want the centers to stay soft.
Cool the cookies on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely before serving or storing.
