Equipment

  • 9×9-inch baking pan - to bake your bars. I love this pan 9x9 pan from USA Bakeware.
  • Parchment paper - to line your pan for easy removal of the bars.
  • Food processor (optional) - for making the shortbread crust. You can also mix this by hand.
  • Fork - to dock the crust.
  • Medium sized pot - to cook the cherry pie filling.
  • Mixing bowls - to mix the crust and crumble.
  • Whisk - to mix the glaze.
  • Spatula - to mix the compote and spread.
  • Digital kitchen scale (optional) - for accurate measuring, especially helpful with sourdough baking. I linked the one I like here.
  • Measuring cups and spoons - for measuring ingredients.
  • Oven safe metal clips (optional) - for holding the foil down to the pan. I love these metal clips that are heat safe and keep my foil from sliding around.

Instructions
 

Step 1: Make the Shortbread Crust

  • To start, you need to prepare the buttery shortbread crust that makes the base of the bars. Preheat the oven to 350°F (175°C). Line a 9×9 pan with parchment, leaving overhang. Don't skip this step, it's key to removal of the bars later. Without the parchment they'll stick the the pan!
  • In a medium sized bowl, add the butter and melt it. Whisk the butter until it's smooth.
    10 (140g) Tbsp unsalted butter
  • Add the sourdough discard to the butter, and whisk it again until smooth.
    1/4 (60g) cup sourdough discard
  • Measure the flour, sugar, and salt into the bowl with the butter discard mixture. Mix the dough with your hands until a crumbly mixture forms. Avoid overmixing the shortbread crust, or it will become tough.
    1/3 (65g) cup granulated white sugar, 1 3/4 (220g) cups all-purpose flour, 1/4 tsp fine sea salt
  • Once the dough starts to form, transfer to the pan lined with parchment and press the dough firmly and evenly into the pan. If needed, you can cover the shortbread crust with more parchment paper and press with a measuring cup or rolling pin to help smooth the shortbread out to make it even.
  • Dock the bottom with a fork all over, by making small holes all over the bottom.
  • Optional Overnight Fermentation: Cover the shortbread crust with plastic, and refrigerate overnight. This allows the sourdough discard to work to ferment the dough. Remove from the refrigerator and bake the next day as directed below.
  • Bake the crust for 20 minutes until lightly golden at the edges. Allow to cool while you make your cherry pie filling and crumble.

Step 2: Make the Cherry Pie Filling

  • If using fresh cherries, remove all of the stems and pits first.
    3 (450g) cups dark sweet cherries
  • Add the frozen or fresh cherries, sugar, and lemon juice to a medium sized pot or saucepan. Cook the mixture over medium heat, stirring with a spatula to avoid the bottom burning, for about 5 minutes.
    1/2 (100g) cup granulated sugar, 1 (8g) Tbsp lemon juice
  • In a small bowl, add the cold water and cornstarch. Whisk together until smooth.
    2 (16g) Tbsp cornstarch, 1 (8g) Tbsp cold water
  • Add the cornstarch slurry to the cherry pie filling, and whisk constantly to avoid clumps.
  • Cook the cherries another 4-5 until thick and jammy. Remove from heat, and set aside the cherry pie filling to cool slightly while you prepare the crumble topping.

Step 3: Make the Oat Crumble Topping

  • Melt the butter for the crumble in the microwave, then whisk until smooth.
    6 (85g) Tbsp unsalted butter
  • Add the discard to the butter, and whisk again until smooth.
    2 (30g) Tbsp sourdough discard
  • Measure the flour, oats, brown sugar, and salt to the butter discard mixture, and mix with your hands until a crumbly mixture forms. Set aside for assembling the bars.
    1 (125g) cup all-purpose flour, 3/4 (64g) cup rolled old-fashioned oats, 1/2 (100g) cup light brown sugar, 1/4 tsp fine sea salt
  • Optional Overnight Fermentation: Cover the crumble with plastic, and rest at room temperature overnight. This allows the sourdough discard to work to ferment the crumble. You can skip this step!

Step 4: Bake the Cherry Pie Bars

  • Make sure your oven is preheated oven to 350°F (177°C).
  • Pour the cherry pie filling on top of the shortbread crust, and spread the filling evenly over the crust to form an even layer to the edges of the pan.
  • Sprinkle the oat crumble evenly over the top of the cherry pie filling, making sure to meet the edges.
  • Transfer the bars to the hot oven, and bake for 40 minutes, or until the topping is golden brown and the filling is bubbling around the edges.
  • Remove the bars from the oven, and allow the bars to cool completely before glazing. This is a key step; if you skip allowing them to cool, the filling will run everywhere.

Step 5: Glaze the Bars

  • In a small bowl, add the powdered sugar, almond extract (if using), and 1 Tablespoon of milk.
    1 (120g) cup powdered sugar, 1/4 tsp almond extract, 1-2 Tbsp whole milk
  • Start to whisk the glaze and bring it together, and add the milk or half and half one teaspoon at a time while you're whisking until the glaze has reached you're desired consistency.
  • You want the glaze to still be thick, but able to slowly run off the spoon.
  • Drizzle the glaze over the top of the cherry pie bars. Allow the glaze to set up for about 15-20 minutes before slicing. Cut the bars into 9 even sections and serve!
  • Yields 9 bars
