Ingredients You’ll Need

100 g unsalted butter/baking spread: Provides richness and moisture. If you’re dairy-free, swap in a vegan butter alternative.
175 g light brown soft sugar: Adds sweetness and helps achieve a chewy texture. You can use coconut sugar for a healthier alternative.
100 g unfed sourdough discard: The star of the show! It gives unique flavor and helps with chewiness. If you don’t have discard, a little plain yogurt or buttermilk could work in a pinch.
1 medium/large egg: Binds everything together for a perfect cookie. Room temperature eggs work best.
1 tsp vanilla extract: A dash of vanilla enhances the overall flavor profile. Use pure vanilla for the most authentic taste.
135 g plain flour: The base ingredient that provides structure. Whole wheat flour can be a healthier substitute.
150 g rolled oats: Gives a hearty, chewy component. Quick oats can be substituted, but will alter texture slightly.
1 tsp ground cinnamon: A warming spice that complements oats beautifully. Feel free to add nutmeg for an extra layer of flavor.
1/2 tsp sea salt: Balances sweetness and enhances all the other flavors.
1/2 tsp bicarbonate of soda: The leavening agent that helps cookies rise. Baking powder can be used in its place if needed.
200 g raisins: Adds natural sweetness and chewy texture. Swap with other dried fruits like cranberries or chopped dates if you prefer.

How to Make Sourdough Oatmeal Raisin Cookies

Preheat your oven: Start by heating your oven to 350°F (175°C). This ensures even baking.
Cream the butter and sugar: In a mixing bowl, beat together 100 g of unsalted butter and 175 g of light brown soft sugar until the mixture is light and fluffy, about 3-4 minutes. This step is crucial for a tender cookie.
Add the sourdough discard: Mix in 100 g of unfed sourdough discard, blending it well with the butter-sugar mix.
Incorporate the egg and vanilla: Beat in 1 medium/large egg and 1 tsp of vanilla extract until fully combined.
Combine dry ingredients: In a separate bowl, whisk together 135 g of plain flour, 150 g of rolled oats, 1 tsp of ground cinnamon, 1/2 tsp of sea salt, and 1/2 tsp of bicarbonate of soda. This helps evenly distribute the leavening agent and spices.
Mix wet and dry ingredients: Gradually add the dry mixture to the wet ingredients, stirring until just combined. Be careful not to overmix here!
Fold in the raisins: Gently fold in 200 g of raisins until evenly distributed throughout the cookie dough.
Scoop the dough: Using a tablespoon or cookie scoop, drop rounded balls of dough onto a parchment-lined baking sheet, spacing them about 2 inches apart for spreading.
Bake the cookies: Place the baking sheet in the preheated oven and bake for 10-12 minutes, or until the edges are golden brown and the centers look slightly undercooked.
Cool on wire racks: Once baked, allow the cookies to cool on the baking sheet for 5 minutes before transferring them to wire racks to cool completely. This cooling time helps them firm up.

Storing & Reheating

To keep your Sourdough Oatmeal Raisin Cookies fresh, store them in an airtight container at room temperature for up to 5 days. For longer storage, refrigerate them in a sealed container for up to 2 weeks. You can also freeze them for up to 3 months. Just place them in a freezer-safe bag. When you’re ready to enjoy, reheat the cookies in the microwave for about 10-15 seconds. They might soften a bit after freezing but a quick reheat will restore their deliciousness.

Chef’s Helpful Tips

Avoid overmixing: Overmixing the dough can lead to tough cookies. Stir until just combined for the best texture.
Ingredient temperature matters: Using room temperature butter and eggs helps create a smooth batter that combines easily and bakes evenly.
Watch your baking time: Every oven is different; if these are your first cookies, keep an eye on them as they bake so you achieve that perfect golden edge.
Texture issues?: If your cookies turn out too dry, it might be due to too much flour. Use a kitchen scale for accuracy.
Try adding nuts: Chopped nuts like walnuts or pecans can add a delightful crunch that complements the chewiness of the oats and the sweetness of the raisins.

Sourdough Oatmeal Raisin Cookies are not only delicious but also a fantastic way to make use of your sourdough discard. Made with love, they invite you to enjoy that cozy feeling of home-baked goodies. Feel free to modify the recipe based on your taste and ingredient availability. Experimentation is the key to creating your perfect cookie, so gather your ingredients and enjoy the process!

Recipe FAQs

Can I use fed sourdough instead of unfed?

Yes, you can use fed sourdough for this recipe. Just remember that it may add a bit more moisture and tang, which can enhance the flavor, but it’s best to stick with unfed for the intended taste and texture.

How can I make these cookies gluten-free?

To make Sourdough Oatmeal Raisin Cookies gluten-free, simply replace the plain flour with a 1:1 gluten-free baking blend. Ensure that your oats are certified gluten-free as well, as cross-contamination can be an issue.

What can I substitute for raisins?

If you’re not a fan of raisins, feel free to use other dried fruits like cranberries, chopped apricots, or even chocolate chips for a sweeter twist. Each substitute will change the flavor profile slightly but will still be delicious!

How do I know when my cookies are done baking?

Look for golden edges and a slightly soft center. They will firm up as they cool. Remember not to worry if they look underbaked when you take them out; they’ll continue to cook from the residual heat.
