Step 1

Preheat the oven to 375 degrees F. Prepare a 8×8-inch baking pan with the non-stick coating of your choice.

Step 2

For the crumb and crust, whisk together flour, sugar, baking powder and salt.

Step 3

Next, cut in the cold butter using two forks or a pastry cutter then slowly mix in the egg yolk and cold water. Don't worry if the dough seems really crumbly. It should be!

Step 4

Next take half of the crumble mixture and press into the prepared pan. The rest should be saved for the top of the bars.

Step 5

Stir together peach slices, lemon juice, flour, sugar, cinnamon, nutmeg and vanilla until combined.

Step 6

To assemble, evenly add peach filling to top of crust.

Step 7

Next sprinkle the remaining crumble over the top of the peach filling.

Step 8

Bake for 30-38 minutes or until golden brown and set.

Step 9

Cool bars to room temperature then cut and serve.
