3 tablespoons butter, cubed 
2 cups chopped peeled Gala apple 
1/2 cup packed brown sugar, divided 
1/4 cup brewed coffee 
2/3 cup canola oil 
1/2 cup sugar 
1 large egg plus 1 large egg white, room temperature 
2 teaspoons vanilla extract 
1-1/2 cups all-purpose flour 
2 teaspoons ground cinnamon 
1/2 teaspoon salt 
1/2 teaspoon baking soda 
1/4 teaspoon ground nutmeg 
DRIZZLE:
1/3 cup brewed coffee 
1/4 cup heavy whipping cream 
1-1/2 cups confectioners' sugar
1. Preheat oven to 375°. In a 10-in. cast-iron or other ovenproof skillet, melt butter over low heat. Add apple and 1/4 cup brown sugar. Cook and stir until crisp-tender, about 5 minutes. Stir in coffee; remove from heat. 
2. In a large bowl, beat oil, sugar, egg, egg white, vanilla and remaining 1/4 cup brown sugar until well blended. In another bowl, whisk flour, cinnamon, salt, baking soda and nutmeg; gradually beat into oil mixture. Gently spread over apple mixture. 
3. Bake until a toothpick inserted in center comes out clean, 18 to 22 minutes. Cool on a wire rack 10 minutes. 
4. Meanwhile, for drizzle, in a small saucepan, bring coffee and cream to a boil; cook until liquid is reduced to 1/4 cup, 10 to 12 minutes. Remove from heat; stir in confectioners' sugar. Let stand 10 minutes. Drizzle over cake.
