Overnight Sourdough Jam Bars with a Dairy-Free Twist

It all began on one of those quiet weekend mornings when the house still felt hushed, and the sun had only just begun to spill across the kitchen counter. I remember standing there, holding a jar of berry jam in one hand and a bowl of leftover sourdough discard in the other, wondering what I could possibly make that would be both simple and satisfying. My sourdough starter had been bubbling away all week, and like many home bakers, I faced the familiar question of what to do with the discard. That moment became the spark for my very first batch of Overnight Sourdough Jam Bars.

The process was soothing from the start—flakes of oats mixing with creamy coconut oil, the subtle tang of the discard blending right in. As the jam baked later that morning, its rich berry scent filled the air, mingling with the wholesome aroma of toasted oats. It reminded me a little of childhood breakfasts but with a grown-up twist—lightly fermented, layered, and just sweet enough. I realized that baking doesn’t have to mean butter and cream to taste indulgent; dairy-free alternatives can create just as much warmth and comfort. That discovery opened my eyes to a new wave of dairy-free sourdough recipes, especially those designed for simple, everyday enjoyment.

That first batch of jam bars quickly became my favorite among all my breakfast discard recipes. The texture was soft yet sturdy, and the jam added a touch of brightness that paired perfectly with a morning coffee. Most importantly, they captured everything I love about sourdough baking—the balance of resourcefulness and creativity, where nothing goes to waste, and each bake becomes a little act of care.

    Step-by-Step Preparation Method

    Overnight Prep – Letting the Flavors Develop

    The magic here comes from time. Combine sourdough discard, oats, flour, coconut oil, and sugar the night before, and let natural fermentation enrich the mix while you sleep. This overnight rest transforms a simple dough into a tender base perfect for an overnight sourdough breakfast.

    Mix discard with melted coconut oil, then fold in oats, sugar, and salt until soft and slightly sticky. Cover and let rest 8–12 hours at room temperature for mild fermentation that enriches flavor without bitterness. Adjust for climate by refrigerating early if warm or extending time in cooler kitchens. By morning, your dough will be lightly puffed and aromatic—ready to bake a healthy sourdough breakfast that starts itself while you rest.

    Baking to Perfection and Enjoying the Result

    Give the dough a quick stir and press two-thirds into a parchment-lined pan for the base. Spread jam evenly, then mix the remaining dough with extra oats, syrup, and dairy-free butter to sprinkle as a crumble. Bake at 350°F (175°C) for 28–35 minutes, until the edges are golden and the jam bubbles gently.

    Cool fully before slicing for neat edges and well-set layers. Each golden square combines chewy oats, tangy base, and bright jam—a blissful balance of classic and modern dairy-free sourdough recipes. Store in an airtight container three days at room temperature, a week refrigerated, or freeze portions for quick breakfast discard recipes.
