Ingredients You Will Need

Here is a complete list of ingredients to make your cookie bars soft, chewy, and full of flavor. Use measuring cups and spoons for accuracy.

• 1 cup unsalted butter (softened at room temperature)

• 1 cup brown sugar (packed)

• ½ cup white granulated sugar

• 1 cup sourdough starter discard (unfed)

• 2 large eggs

• 2 teaspoons pure vanilla extract

• 2 ½ cups all purpose flour

• 1 teaspoon baking soda

• ½ teaspoon baking powder

• ½ teaspoon salt

• 1 ½ cups chocolate chips (semi sweet or milk chocolate)

• Optional: ½ cup chopped nuts (walnuts or pecans for extra crunch)

Step by Step Method

Step 1: Prepare the baking pan

Preheat your oven to 350 degrees Fahrenheit (180 degrees Celsius). Take a square baking pan, about 9×9 inches, and line it with parchment paper. Leave some extra paper hanging over the sides so you can easily lift the bars out later. Lightly grease the paper with a small amount of butter or oil spray. This will help prevent the cookie bars from sticking.

Step 2: Mix the butter and sugars

In a large mixing bowl, add the softened butter, brown sugar, and white sugar. Use a hand mixer or stand mixer to beat them together until the mixture looks light and fluffy. This step usually takes about 2 to 3 minutes. Beating well helps create air pockets in the batter, making the bars soft and tender.

Step 3: Add eggs and vanilla

Crack the eggs into the bowl one at a time. Mix well after adding each egg. Then add the vanilla extract. The eggs help bind everything together, while vanilla adds that warm cookie aroma we all love. Your batter should now look smooth and creamy.

Step 4: Add the sourdough starter

Now it is time to add your sourdough discard. Pour in one cup of unfed sourdough starter and mix it until everything is well combined. The sourdough adds moisture, a light tangy flavor, and helps the cookie bars stay soft for days. It also gives your recipe a deeper flavor than regular cookies.

Step 5: Combine dry ingredients

In a separate bowl, mix together the flour, baking soda, baking powder, and salt. Stir them gently with a whisk or fork so everything is evenly combined. This helps the leavening agents spread evenly through the dough.

Step 6: Mix wet and dry ingredients together

Slowly add the dry mixture into the wet ingredients. Mix at low speed until you see no more streaks of flour. Be careful not to overmix. Overmixing can make your cookie bars tough instead of soft. The dough should be thick but still easy to spread.

Step 7: Add chocolate chips and nuts

Now add your chocolate chips and, if you like, some chopped nuts. Gently fold them into the dough using a spatula or wooden spoon. Make sure they are evenly distributed so every bite gets some chocolate.

Step 8: Spread the dough in the pan

Transfer the dough into your prepared baking pan. Use a spatula to spread it out evenly into all corners. Smooth the top gently. You can press a few extra chocolate chips on top if you want a pretty finish.

Step 9: Bake the cookie bars

Place the pan in your preheated oven and bake for about 25 to 30 minutes. Baking times can vary depending on your oven, so start checking around the 25-minute mark. The cookie bars are ready when the edges are golden brown, and the center looks set but still a little soft.

Step 10: Cool and slice

Once baked, remove the pan from the oven and let it cool completely on a wire rack. Cooling is important because the bars will firm up as they rest. After about 30 minutes, use the parchment paper to lift the cookie slab out of the pan. Place it on a cutting board and slice into squares or rectangles. Now your Sourdough Chocolate Chip Cookie Bars are ready to enjoy.

Why This Recipe Is Special

These cookie bars are special for many reasons. First, they give you a smart way to use leftover sourdough discard. Instead of throwing it away, you turn it into something delicious and comforting. That means less waste and more joy. The sourdough adds a natural tang that balances the sweetness of the chocolate. It also helps make the cookie bars soft, chewy, and moist for days, unlike regular cookies that can dry out fast.

Another reason this recipe stands out is its simplicity. You do not need fancy tools or baking skills. Every step is easy to follow, making it perfect even for beginners. The ingredients are common and affordable, yet the final taste feels gourmet. You can make these bars in less than an hour, and they will taste like they came from a bakery.

Health wise, sourdough offers some benefits too. It may be easier to digest because the fermentation process breaks down some of the gluten. It also has a lower glycemic index compared to regular flour, which means it might cause a slower rise in blood sugar. While these cookie bars are still a treat, they can be a slightly better option than other sweets. Plus, the joy of baking from scratch and the happiness of sharing homemade treats is good for the soul.

Extra Tips for Better Taste

1. Use quality chocolate chips – Choose a good brand of semi sweet or dark chocolate chips. High quality chocolate melts better and gives a rich taste.

2. Do not overbake – Take the bars out when the center still looks slightly soft. They will continue to bake a little as they cool, keeping the inside chewy.

3. Add a pinch of coffee powder – A small amount of instant coffee or espresso powder enhances the chocolate flavor without making it taste like coffee.

4. Chill the dough – For even thicker bars, chill the dough in the fridge for about 30 minutes before baking. This helps the flavors develop and gives a richer texture.

5. Mix chocolate types – Use a combination of milk, dark, and white chocolate chips for extra depth of flavor.

6. Sprinkle sea salt on top – A light sprinkle of flaky sea salt after baking makes the sweetness pop and adds a gourmet touch.

7. Add flavor twists – Try adding shredded coconut, cinnamon, or orange zest for a fun change.

8. Use brown butter – If you want a deeper nutty flavor, brown your butter before mixing it with sugar. Let it cool slightly before using.

9. Store properly – Keep the cookie bars in an airtight container at room temperature for up to 5 days. You can also freeze them for longer storage.

10. Warm before serving – A few seconds in the microwave makes the chocolate melt again and brings back the freshly baked taste.
