Sheet-Pan Gala Apple Slab Cake with Cinnamon Glaze

Serves 6 · 20 min prep · 32 min cook

Ingredients

• 3 medium Gala apples
• 1 3/4 cups all-purpose flour
• 1 1/2 tsp baking powder
• 1/2 tsp baking soda
• 2 tsp ground cinnamon
• 3/4 tsp kosher salt
• 1/2 cup unsalted butter
• 3/4 cup granulated sugar
• 1/4 cup packed light brown sugar
• 2 large eggs
• 2 tsp vanilla extract
• 1/2 cup sour cream
• 1/4 cup whole milk
• 1 cup powdered sugar
• 2 tbsp apple cider or milk

Instructions

1. 1Heat the oven to 350°F and line a rimmed quarter sheet pan with parchment, leaving a slight overhang for easy lifting.
2. 2Peel and dice the Gala apples into 1/2-inch pieces and pat them dry with a towel so excess moisture does not sog the batter.
3. 3Whisk the flour, baking powder, baking soda, most of the cinnamon, and salt in a bowl until evenly combined.
4. 4In a large bowl beat the softened butter with both sugars until light and fluffy, about 2 minutes, then beat in the eggs one at a time and the vanilla.
5. 5Alternate adding the dry mixture and the sour cream plus milk, mixing just until no dry streaks remain; fold in the diced apples.
6. 6Spread the thick batter evenly into the prepared pan, smoothing the top with an offset spatula so it bakes level.
7. 7Bake 28 to 34 minutes until the center springs back, a toothpick comes out with a few moist crumbs, and the edges are golden brown.
8. 8Cool the slab in the pan 15 minutes, then lift out onto a rack.
9. 9Whisk the powdered sugar with the remaining cinnamon and enough cider to make a thick pourable glaze; drizzle over the slightly warm cake.
10. 10Let the glaze set 10 minutes, then cut into neat rectangles for sharing or packing in lunchboxes.
