Step‑by‑Step Instructions for Jam Filled Sourdough Breakfast Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it’s warming up, line an 8-inch square baking pan with parchment paper, letting the edges hang over for easy lifting later. This will create the perfect base for your Jam Filled Sourdough Breakfast Bars, and will ensure they don’t stick to the pan.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, combine the sourdough discard, melted unsalted butter, and light brown sugar. Stir these ingredients together until you have a smooth mixture, ensuring everything is well combined. This forms the flavorful base of your bars, which will provide both moisture and sweetness.
Step 3: Incorporate the Dry Ingredients
Next, add the old-fashioned oats, white whole wheat flour, and salt to the wet mixture. Using a spatula or wooden spoon, mix everything until it’s just combined, avoiding overmixing. You want a thick, doughy consistency that will hold together beautifully when pressed into the pan, giving your Jam Filled Sourdough Breakfast Bars their signature texture.
Step 4: Press the Dough into the Pan
Take roughly two-thirds of the dough and press it evenly into the bottom of your prepared baking pan. Use the back of a measuring cup or your fingers to ensure the layer is level and compacted. This will act as the sturdy foundation for the filling, making sure each bite is deliciously satisfying.
Step 5: Add the Jam Layer
Carefully spread your chosen jam or preserves evenly over the pressed dough in the pan. Aim for an even layer that covers the entire surface, as this will ensure every bite of your Jam Filled Sourdough Breakfast Bars bursts with fruity flavor. Choose your favorite jam for the ultimate customization!
Step 6: Crumble the Remaining Dough
Now, crumble the remaining dough over the jam layer, using your fingers to break it into small pieces. Lightly press down on the crumbles to slightly meld them with the jam. This creates a delightful topping, giving your bars a beautiful texture and ensuring they hold together nicely when baked.
Step 7: Bake to Perfection
Place the baking pan in your preheated oven and bake for 30-35 minutes. Keep an eye on the bars; they’re done when the jam is bubbling and the top is lightly golden. This step is crucial for achieving that perfect chewy texture in your Jam Filled Sourdough Breakfast Bars.
Step 8: Cool and Slice
Once baked, remove the pan from the oven and let it cool completely on a wire rack. This cooling step is vital as it helps the bars firm up. For even firmer bars, consider chilling them in the refrigerator before slicing into squares, ensuring they are easy to grab and enjoy on the go!
