Preheat the oven to 350F and line an 8*8 inch pan with parchment paper. Then, add the vegan butter, cane sugar, brown sugar, and vanilla to a mixing bowl. Whip together with an electric mixer until fluffy and creamed, about 2-3 minutes.
Then, add the flour, baking powder, and salt to the mixing bowl and mix everything together into a thick dough. Press the dough into the parchment-lined pan until it is spread out evenly. Then, add to the oven to par-bake for 15 minutes.
Make the Apple Pie Filling & Streusel
While the crust is baking, make the apple pie filling and streusel. Peel two apples and thinly slice them into ¼ inch slices. Then, add to a bowl and mix with the rest of the apple pie filling ingredients including the sugar, cornstarch, lemon juice, cinnamon, and nutmeg. Mix together until the apples are evenly coated and set aside.
Next, make the streusel. Add the rolled oats, brown sugar, flour, and cinnamon to a bowl. Then, add in the butter and use your fingers or a fork to cut the butter into the dry ingredients until a crumbly streusel forms. Set aside until the crust has finished baking
Layer & Bake
Remove the partially baked crust from the oven and top with the apple pie filling. Then, sprinkle the streusel on top.
Add the apple pie bars to the oven and bake for another 30-35 minutes.
Remove from the oven and let cool completely before slicing. For the best results, put the cooled bars in the fridge 1-2 hours before slicing.
Slice into 9 even slices and enjoy! Before serving, drizzle with vegan salted caramel if desired.
Notes
Leftovers can be stored in the fridge for 3-4 days or in the freezer for up to 1 month between sheets of parchment paper in a closed container.
I highly recommend topping these apple bars with a drizzle of vegan salted caramel!
Cornstarch- can be subbed 1:1 for arrowroot powder.
Lemon juice- can be subbed 1:1 for any acidic fruit juice such as lime or freshly squeezed orange juice. It will affect the flavor slightly, but works!
Vegan butter- can be subbed for coconut oil, but keep in mind it will affect the flavor. If using coconut oil, it must be completely solid for the best results.
