Ingredients
• 1 cup all-purpose flour, spooned into measuring cup and leveled off
• 1 teaspoon baking powder
• ¼ teaspoon salt
• ½ cup (1 stick) unsalted butter, at room temperature
• ⅔ cup granulated sugar, plus more for sprinkling over cake
• 2 large eggs
• 1 teaspoon vanilla extract
• 3 tablespoons dark rum
• 2 baking apples, peeled, cored and cut into ½-inch cubes (3½ to 4 cups chopped; see note)
• Confectioners’ sugar (optional), for decorating cake
Instructions
• Preheat the oven to 350°F (175°C) and set an oven rack in the middle position. Grease a 9-inch (23-cm) springform or regular cake pan with butter or nonstick cooking spray. If using a regular cake pan, line the bottom of the pan with parchment paper and grease again.
• In a small bowl, whisk together the flour, baking powder and salt.
• Using a handheld mixer with beaters or a stand mixer with the paddle attachment, cream the butter and granulated sugar until light and fluffy, about 3 minutes. Add the eggs, one at a time, beating well and scraping down the sides of the bowl after each addition. Beat in the vanilla and rum. Don’t worry if the batter looks grainy at this point; that’s okay. Add the flour mixture and mix on low speed until just combined. Using a rubber spatula, fold in the chopped apples.
• Scrape the batter into the prepared pan and even the top. Sprinkle evenly with 1 tablespoon of granulated sugar. Bake for about 40 minutes, or until the cake is golden and a toothpick inserted into the center comes out clean. Allow the cake to cool on a rack in the pan. Once cool, run a blunt knife around the edges of the cake. If using a springform pan, remove the sides. If using a regular cake pan, carefully invert the cake onto the rack, remove the parchment paper, then gently flip the cake over and place right-side-up on a platter. Using a fine sieve, dust with confectioners’ sugar (if using). Cake can be served warm or room temperature, plain or with lightly sweetened whipped cream or vanilla ice cream.
Step-by-Step Instructions
Begin by combining the flour, baking powder and salt in a small bowl.

No need to sift; just whisk well.

Set aside. Then, in the bowl of an electric mixer, cream the butter and sugar until light and fluffy.

Add the eggs one at a time.

Beat in the vanilla extract and rum.

It will look a little curdled at this point; that’s okay.

Add the dry ingredients to the wet ingredients.

Mix until just combined.

Add the peeled and chopped apples.

Use a rubber spatula to fold the apples into the batter.

Have a 9-inch springform pan greased, or a 9-inch cake pan greased, lined with parchment, and greased again.

Scrape the batter into the prepared pan and even the top.

Sprinkle with 1 tablespoon of granulated sugar.

Bake the cake for about 40 minutes, until golden and crisp on top.

Serve warm or room temperature, plain or with lightly sweetened whipped cream or a scoop of vanilla ice cream. A dash of cinnamon would be a nice addition, too.
