Preparation

• Preheat the oven to 350°F. Line a 9" square pan with a parchment sling and lightly grease.
• In a large skillet, melt the butter over medium-high heat. Add the cinnamon and salt and stir to combine.
• Add the apples to the skillet and stir to coat in the butter mixture. Cook for about 5 minutes, stirring occasionally, until the apples just begin to soften.
• Sprinkle the sugar evenly over the apples and stir to combine. Cook, stirring occasionally, for about 5 minutes. Allow the apple mixture to cool in the pan, off the heat.
• In a large bowl, combine the flour, baking powder, sugar, salt, and spice. Add the butter and mix until the mixture looks sandy.
• With the mixer running on low speed, beat in the eggs one at a time until fully incorporated, scraping the bowl as needed.
• With the mixer running at low speed, add the vanilla and milk. Once the milk is absorbed, scrape the bowl and mix at medium-high speed for 1 minute.
• Transfer the batter to the prepared pan and spread it into an even layer. Spoon the apple topping evenly over the batter.
• Bake the cake for 60 to 65 minutes or until a paring knife inserted in the center comes out clean. Cool for 30 minutes before removing from the pan.
• In a small bowl, combine the glaze ingredients, starting with 1.5 tablespoons of milk; whisk until smooth. Drizzle over the cooled cake.
• Allow the glaze to set briefly before slicing and serving.
