Step 1

Preheat your oven to 375F.Next, line a 9x13 pan with parchment or tinfoil. Make sure it's long enough that the material hangs over the edges so you can pick up the bars out of the pan once they're done by holding the tinfoil or parchment. Spray your tinfoil with cooking spray or butter your parchment paper.

Step 2

In a large bowl, combine your flour, sugar, baking powder, salt, cinnamon, and mix gently.

Step 3

Take your butter right from the fridge when it's still cold. Grate it with a cheese grater or dice it into small pieces. Add the butter to the flour mixture and combine everything until the butter is coated with the flour mixture.

Step 4

Next, add one egg to the flour and butter mixture and combine well. The mixture should ultimately look like it has roughly pea-sized pieces of butter in it.

Step 5

Now, take HALF of this dough, and press it into the bottom of your pan on top of the tinfoil or parchment paper. This will be the base and crust, so you'll want to press it in fairly firmly to give your bars a solid base.

Step 6

Refrigerate the pan with the crust in the bottom and also take the other half of the dough and refrigerate that too.

Step 7

Peel, slice, and dice about eight small peaches or six large (or however many gets you about five cups of peaches).It's okay if your pieces aren't all the same size.(See section in blog post about the easiest way to peel peaches)

Step 8

Add your lemon juice and vanilla to your peaches, mix gently, and set aside.

Step 9

In a separate bowl, whisk together the brown sugar, flour, rolled oats, salt, cinnamon, nutmeg, and shredded coconut (if you're using it).

Step 10

Now, gently combine the peach mixture with the dry ingredients.

Step 11

Get the pan with the crust out of the fridge, and pour your peach filling on top of it.

Step 12

Take the rest of your crisp base and topping from the fridge, and cover the peach filling mix in the pan with it. Bake in the preheated oven for 50-60 minutes until the top is light golden.

Step 13

Remove from the oven and let it come to room temperature on the counter before you move it to the fridge. Alternatively, serve them hot with ice cream!After it's been in the fridge for at least an hour, take it out and pull the edges of the parchment or tinfoil to remove the entire thing from the pan.Place it on a large cutting board and cut it into pieces of your desired size. Store in an airtight container.
