Ingredients

For the cake

1 1/2 cups all-purpose flour
3/4 cups rolled oats or large flake oats
3/4 tsp baking powder
3/4 tsp baking soda
1 1/2 tsp cornstarch
1/4 tsp salt
1 tsp cinnamon + 1/4 tsp for dusting apples
Dash of allspice optional
Dash of cloves optional
Dash of nutmeg optional
1/2 cup oil
3/4 cups unsweetened applesauce* room temperature
3/4 cups light brown sugar room temperature
1 tbsp vanilla
2 large eggs room temperature
1 medium-sized Granny Smith apple* shredded
1 medium-sized Granny Smith apple cut in cubes

For the topping

3 tsp white sugar
1/4 tsp cinnamon

Instructions

Prep

Preheat the oven to 350℉/180℃. Line the pan with parchment paper and set aside.
Peel the apples. Cut one of the apples into small cubes, and shred the other one. I like to do both as it brings more texture to the cake, but you can also just cut them or shred them both. Add 1/4 tsp on top and mix around to evenly coat them and set aside.

For the cake

In a medium sized bowl, add in the dry ingredients. Stir to combine and set aside.
1 1/2 cups all-purpose flour, 3/4 cups rolled oats, 3/4 tsp baking powder, 3/4 tsp baking soda, 1 1/2 tsp cornstarch, 1/4 tsp salt, 1 tsp cinnamon, Dash of allspice, Dash of cloves, Dash of nutmeg
In a large bowl, add the wet ingredients. Whisk for 2-3 minutes until well combined. Make sure to scrap the sides of the bowl when needed.
1/2 cup oil, 3/4 cups unsweetened applesauce*, 3/4 cups light brown sugar, 1 tbsp vanilla, 2 large eggs
Add the dry ingredients. With a spatula, gently fold until a batter forms. Do not over-mix!
Add the apples into the bowl. Gently mix until JUST combined, it's so important not to over-mix!

Spread the batter into the prepared pan. In a small cup, add white sugar and cinnamon and mix together. Then sprinkle on top evenly. This will give you a sweet crunchy top.
3 tsp white sugar, 1/4 tsp cinnamon
Bake for 40-50 minutes, depending on your oven. A toothpick inserted will come out clean when it is ready.

Notes

*Apples – I used 2 large Granny Smith apples. You can use any kind of apples. I prefer using a tart apple in this cake as it compliments well with the sweetness. I had 2 cups total, with 1 cup being shredded and 1 cup sliced into small cubes. I chopped them with the skin off, but you can keep it if you wish. You can also JUST chop them or shred them, I prefer doing both for more texture :)

*Applesauce - You can use unsweetened or sweetened, but if you use sweetened the cake will be sweeter (obviously haha!)
