Method
Preparation
- Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan.
- In a bowl, whisk together the flour, baking powder, baking soda, salt, and ground cinnamon. Set it aside.
- In a separate large bowl, cream together the softened butter and granulated sugar until light and fluffy (about 3-4 minutes).
- Beat in the eggs one at a time, followed by the vanilla extract. Mix until well combined.
- Add the sour cream and mix until the batter is smooth.
- Gradually add the dry ingredients to the wet mixture, stirring until just combined.
- Gently fold in the chopped apples and walnuts (if using), ensuring they are evenly distributed.
- Pour the batter into your prepared pan and smooth out the top.
- In a small bowl, mix together the brown sugar and additional cinnamon; sprinkle it evenly over the batter.
Baking
- Bake in the preheated oven for 40-50 minutes, or until a toothpick inserted in the center comes out clean.
- Let the cake cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely. Slice and serve as desired.
Notes
For the best flavor, use a mix of sweet and tart apples like Granny Smith and Honeycrisp. Store in an airtight container in the refrigerator for up to a week, or freeze for up to three months.
