1-First Step: Preheat your oven to 350°F. Prepare a mini round cake pan so it is ready for the sticky brown sugar mixture. This is the kind of recipe where a little prep up front saves you from scrambling once the dough is mixed. If you are the type who always forgets a pan until the last second, this is your gentle reminder to grab it now.

2-Second Step: Add 1 cup room temperature butter and 1 1/2 cups granulated sugar to a large mixing bowl. Cream them together until the mixture looks light and fluffy. This step matters because it creates the soft, tender texture that makes these pineapple upside down sugar cookies feel more like a bakery treat than a rushed snack.

3-Third Step: Beat in 2 eggs, 2 teaspoons vanilla extract, and 1/2 cup sour cream. Mix until the dough looks smooth and well combined. The sour cream is one of the quiet heroes here, since it helps keep the cookies soft and gives the dough a subtle tang that plays nicely with the sweet topping.

4-Fourth Step: In another bowl, whisk together 3 cups flour, 1 teaspoon baking powder, 1 teaspoon cornstarch, and 1/2 teaspoon salt. The cornstarch helps the cookies stay thick and soft, while the baking powder adds just enough lift. Slowly fold the dry mixture into the wet mixture until cookie dough forms. Try not to overmix, or the dough can get a little tough.

5-Fifth Step: In a separate bowl, combine 1/2 cup melted butter with 1 cup packed light brown sugar. Stir until the mixture looks thick and glossy. This is the part that turns into that sticky, caramel-like layer once the cookies bake. If you love the classic pineapple upside-down cake flavor, this is where the magic starts to happen.

6-Sixth Step: Spoon about 1 tablespoon of the brown sugar mixture into each pan cavity. Top each one with 1 canned pineapple slice and 1 maraschino cherry. Then add about 3 tablespoons of cookie dough on top and flatten gently so it covers the fruit. The dough does not have to be perfect, but it should spread enough to trap the sweet topping inside while baking.

7-Seventh Step: Bake for 25 minutes, or until the edges are golden and the brown sugar is bubbling. The kitchen will smell amazing at this point, and yes, it is completely normal to hover near the oven door. Just try not to open it too often, since that can affect the bake.

8-Eighth Step: Let the cookies cool in the pan for 10 minutes. Then invert them onto wax paper. Cooling briefly in the pan helps the topping settle so it does not run everywhere when you turn them out. If a pineapple slice sticks to the pan, gently reposition it on the cookie after inverting. That little fix is completely normal and usually saves the day.

9-Final Step: Let the cookies cool completely before serving. That gives the brown sugar topping time to set and makes the texture better for eating. These are lovely served warm, but they are also excellent once fully cooled, especially if you like a neat, chewy bite.
