Instructions
1. 
Preheat your oven to 350°F (175°C) and grease a 9×9 inch square baking pan. 
2. 
In a medium bowl, toss the chopped apples with cinnamon and brown sugar until evenly coated; set aside.
3. 
In a separate mixing bowl, whisk together the sifted flour, baking powder, and salt until well combined.
4. In another large bowl, whisk the white sugar, vegetable oil, Greek yogurt, and vanilla extract until very smooth, then add the eggs and whisk again until fully incorporated.
5. 
Gently fold the dry ingredients into the wet mixture until just combined—be careful not to overmix to keep it light.
6. 
Pour half of the cake batter into the prepared pan and spread it out evenly.
7. 
Layer half of the spiced apple chunks over the batter, then pour the remaining batter on top.
8. 
Top with the remaining half of the apples, spreading them across the surface for that signature 2026 rustic texture.
9. 
Bake for 45 to 55 minutes until a toothpick inserted into the center comes out clean.
10. 
Dust with powdered sugar before serving to elevate the presentation.
11. 
Let the bars cool slightly, then slice into squares to serve
