How to Make Brown Butter Sourdough Oatmeal Cookie Bars

Step 1: Preheat and Prepare

First things first, preheat your oven to 350°F (175°C). This ensures your Brown Butter Sourdough Oatmeal Cookie Bars bake evenly. While the oven warms up, grab a 9×13 inch baking pan and grease it well. You can use butter or cooking spray. This step is crucial to prevent sticking, so don’t skip it! Trust me, you want these bars to come out perfectly.

Step 2: Brown the Butter

Now, let’s get to the magic of browning butter! In a saucepan, melt the unsalted butter over medium heat. Keep an eye on it as it transforms from yellow to golden brown. You’ll know it’s ready when it smells nutty and delicious. This step adds a rich flavor that elevates your cookie bars. Don’t rush it; patience is key for that perfect brown butter!

Step 3: Mix the Sugars and Butter

Once your butter is beautifully browned, pour it into a large mixing bowl. Add the brown sugar and granulated sugar to the bowl. Using a whisk or spatula, mix them together until well combined. The warmth of the butter will help dissolve the sugars, creating a smooth mixture. This is where the sweetness begins to shine, setting the stage for your cookie bars!

Step 4: Add Eggs and Vanilla

Next, it’s time to add the eggs and vanilla extract. Crack in the two large eggs and pour in the vanilla. Stir everything together until it’s fully blended. The eggs will add moisture and richness, while the vanilla brings warmth to the flavor profile. This combination is what makes your Brown Butter Sourdough Oatmeal Cookie Bars so irresistible!

Step 5: Incorporate the Sourdough Starter

Now, let’s mix in the star ingredient: the sourdough starter! Add it to your wet mixture and stir until it’s smooth. The sourdough adds a unique tang and depth that sets these bars apart from regular oatmeal cookies. It’s like a secret ingredient that makes everyone wonder what your magic is. Don’t be shy; mix it well!

In a separate bowl, whisk together the rolled oats, all-purpose flour, baking soda, and salt. This step is essential for evenly distributing the leavening agent and ensuring your bars rise perfectly. The oats will give your cookie bars that hearty texture, while the flour provides structure. Make sure there are no lumps; a smooth mixture is key!

Step 7: Mix Wet and Dry Ingredients

Now it’s time to bring it all together! Gradually add the dry ingredients to the wet mixture. Stir gently until just combined. Be careful not to overmix; you want your bars to be chewy, not tough. This is where the magic happens, and you can almost taste the deliciousness already. It’s a beautiful sight!

Step 8: Add Optional Chocolate Chips

If you’re feeling indulgent, now’s the time to fold in those chocolate chips! Gently mix them into the batter until evenly distributed. The chocolate adds a delightful sweetness that complements the nutty flavors of the brown butter and oats. If you prefer a more wholesome treat, feel free to skip this step. Either way, you can’t go wrong!

Step 9: Spread and Bake

Spread the batter evenly into your prepared baking pan. Use a spatula to smooth the top, ensuring it’s level. Pop it into the preheated oven and bake for 25-30 minutes. You’ll know they’re done when the edges are golden brown and a toothpick inserted in the center comes out clean. The aroma will fill your kitchen, making it hard to wait!

Step 10: Cool and Cut

Once baked, remove the pan from the oven and let it cool for a bit. Patience is key here! Allow the bars to cool completely before cutting them into squares. This helps them set and makes for cleaner cuts. Trust me, the wait will be worth it when you take that first bite of your Brown Butter Sourdough Oatmeal Cookie Bars!

  • Use room temperature ingredients for better mixing.
  • Don’t rush the browning process; it enhances flavor.
  • For chewy bars, avoid overmixing the batter.
