3cupschopped applespeeled, cored, and cut into 1/2-inch pieces (about 4 Granny Smith apples)
Caramel Glaze
1cuplight brown sugar
4tablespoonswater
½cupheavy whipping cream
3tablespoonsbutter
Instructions
Preheat the oven to 350 degrees F. Grease a 12-cup bundt pan thoroughly with shortening or butter, then sprinkle in a little flour, tilt the pan to coat every ridge, and tap out the excess. A generous coat of cake release also works.
Whisk the 3 cups all-purpose flour, 1 teaspoon baking powder, 3 teaspoons ground cinnamon, and 1/2 teaspoon salt in a bowl until combined. Set aside.
Add the 1 1/2 cups light brown sugar, 1/2 cup granulated sugar, and 3 large eggs to the bowl of a stand mixer fitted with the paddle attachment. Beat until fully combined, creamy, and bubbly on top.
Beat in the 2 teaspoons vanilla extract, then slowly pour in the 1 1/2 cups canola oil, beating well.
Remove the bowl from the mixer. Add one third of the dry ingredients and fold them in with a wooden spoon or spatula. Repeat with the remaining dry ingredients in two more additions until no flour streaks remain.
Fold in the 3 cups chopped apples until they are coated in batter.
Spoon the batter into the prepared pan and spread it into an even layer.
Bake in the center of the oven for 55 minutes, or until a skewer inserted into the center of the cake comes out clean.
Set the pan on a wire rack for 10 minutes, then turn the cake out onto a large plate or cake stand. Let it cool for the rest of the hour before glazing.
About 30 minutes into the cooling time, make the glaze. Add the 1 cup light brown sugar and 4 tablespoons water to a deep medium saucepan over low heat. Stir with a wooden spoon until the sugar dissolves, then stop stirring.
When the syrup starts bubbling, set a timer for 3 minutes. Do not stir or move the pan while it boils.
The syrup will still look thin at 3 minutes, and that is right. Any longer and the glaze sets hard on the cake.
Remove the pan from the heat and immediately add the 1/2 cup heavy whipping cream and 3 tablespoons butter. Stir with a rubber spatula until smooth. The mixture will bubble up and splatter.
Let the glaze cool for 15 to 20 minutes, then pour it slowly over the cooled cake.
