What kind of apples are the best for baking?

Granny Smith or Honey Crisp apples are the best choice for apple oatmeal bars. They balance the sweet crumb and firm enough to hold their shape during baking.

How to Make Apple Oatmeal Bars

Plan about 50 minutes to make this recipe. Only about 20 minutes of hands on time. And if you have an apple peeler/slicer/corer, you’ll get it made even faster.

In a medium size bowl, combine the flour, salt, baking soda, brown sugar and oats. Using a pastry cutter, cut in the cold butter cubes until the mix resembles coarse crumbs.

Spray an 11×7″ or 8×8″ pan with cooking spray. Press half the crumbs in the bottom of the prepared pan.

Arrange the apple slices on top of the pressed crumbs. Sprinkle the white sugar on top of the apples, then drizzle the 2 tablespoons of melted butter over the sugar.

Top with the remaining crumbs and press down gently on the top with your hand. Bake for 30 minutes or until golden brown.

Why did my apple oatmeal bars fall apart?

The usual reason is cutting them too soon. The bars need to cool and set before slicing. Let the pan cool to room temperature, or chill for 20 minutes to cut clean squares.

Another option is to line the pan with parchment paper so you can lift the bars out.

Can I make apple oatmeal bars ahead of time?

Yes. Bake them a day ahead, cool completely and store in an airtight container in the fridge for up to 4 days. They also freeze well for up to 2 months.

I’ve made this almost 10 times. I think it works better if you make 50% more oatmeal mix. So I make a 1 and 1/2 recipe. There is way more ‘bar’ to work with. you will get a more substantial bar that is easier to cut and holds together better. Give it a go!

These are so good! Very sweet. I used dried apricots instead of apples because I have been looking for an apricot oat bar recipe for years. The kind of oat bar served at all of my favorite coffee shops. I would make this with the apples though next time. Not what I was looking and hoping for but really amazingly delicious.
