Creating Pineapple Upside-Down Cookies is simple! Follow these step-by-step instructions for an amazing treat:

1. Preheat Oven: Set your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. Cream Butter and Sugars: In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
3. Mix in Egg and Vanilla: Add the egg and vanilla extract to the mixture, blending until fully combined.
4. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt.
5. Combine Wet and Dry Mixtures: Gradually add the dry ingredients to the butter mixture, mixing just until combined. Do not overmix.
6. Fold in Pineapple: Gently fold the crushed pineapple into the cookie dough until evenly distributed.
7. Scoop the Dough: Using a cookie scoop or tablespoon, drop dough onto the prepared baking sheet, spacing them about 2 inches apart.
8. Top with Cherries: Press halved maraschino cherries gently into the center of each cookie. If using, sprinkle shredded coconut on top.
9. Bake: Place the baking sheet in the preheated oven and bake for 10-12 minutes, until the edges are golden brown.
10. Cool: Remove from the oven and allow the cookies to cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.
