Preheat oven to 350F
Toss all of the filling ingredients together in a large bowl, set aside.
In a food processor, combine flour, sugar, baking powder, and salt.
Pulse 2-3 times.
Add butter one small cube at a time until a crumble forms, then add the egg yolk and vanilla. It should clump together.
Evenly press 3/4 of the crumble mixture into the bottom of a lined 8x8 pan.
Add the strawberry filing mixture on top and spread evenly.
Add the remaining crumble to the top of the strawberry filling.
Bake 35-45 minutes, until the crust is golden brown and slightly pulling away from the sides. The strawberry filling should be bubbling.
Set aside and let cool.
Combine the glaze ingredients together and mix. Once the bars are fully cooled, drizzle the glaze over the top.
Enjoy!
