Equipment

A metal baking pan is often the best choice for baking due to its superior heat conductivity, which ensures even and consistent baking results. The metal rapidly and evenly distributes heat, helping to achieve a perfectly browned crust and uniform texture throughout your baked goods. Additionally, metal pans typically have a higher thermal conductivity compared to glass or ceramic pans, which means they can help bake items more quickly and with better results. This efficiency can also prevent over-baking, as the pan responds swiftly to temperature changes. Overall, metal pans are reliable and versatile, making them a staple in many kitchens for a wide range of baking tasks.

Ingredients

Ingredients needed for chocolate chocolate chip bars!

• Natural Cocoa Powder: Provides a rich, pure chocolate flavor with a slight acidity that enhances the overall taste. It adds depth and complexity to the chocolate flavor.
• Dark Chocolate: Adds intense chocolate flavor and richness due to its higher cocoa content compared to milk chocolate. It melts beautifully and contributes to the gooey texture!
• Brown Sugar: Brings a moist, chewy texture and a caramel-like flavor. The molasses in brown sugar adds depth and a subtle sweetness, complementing the chocolate.
• Extra Egg Yolk: Contributes to a richer, more tender texture by adding additional fat and moisture. It helps bind the ingredients together and enhances the overall creaminess of the final product.
• Espresso Powder: Intensifies the chocolate flavor. It deepens the overall taste without making the baked goods taste like coffee, just a richer chocolate experience.

Substitutions

• Add Nuts: Incorporate chopped nuts like walnuts, pecans, or almonds to add a satisfying crunch and a nutty flavor that complements the rich chocolate. Nuts also contribute extra texture.
• Add Peanut Butter Chips: Mix in peanut butter chips for a dreamy combination of chocolate and creamy peanut butter. The chips melt slightly and add pockets of peanut butter flavor, creating a delicious contrast with the chocolate.
• Add Caramel Bits: Stir in caramel bits for a gooey, sweet surprise in every bite. The caramel melts and creates chewy pockets of sweetness that blend wonderfully with the chocolate.

Instructions

Let's make chocolate cookie bars

Step 1. Using a handheld mixer or stand mixer, beat the brown sugar, granulated sugar, and butter until combined and fluffy, about 1 minute.

Step 2. Add the egg, egg yolk, and vanilla extract, beat until combined, about 30 seconds. Scrape down the bowl as needed.

Step 3. Whisk together the flour, baking soda, baking powder, salt, cocoa powder, and espresso powder until combined. Add it to the mixture.

Step 4. Fold in the chocolate. Pour into the pan, spreading it out evenly.

Step 5. Bake for 25-28 minutes or until the edges puff and the top looks set, a toothpick inserted should have a few moist crumbs. Do not over bake.

Step 6. Let cool in the pan before cutting and enjoying. Finish with flaky sea salt.

Hint: I always line my baking pan with parchment paper, making sure it goes up and over the sides for easy removal and cleanup.

Pro tips

• Weigh the Ingredients: Use a kitchen scale for precise measurements to ensure consistent results. Accurate ingredient ratios contribute to the perfect texture and flavor of your double chocolate cookie bars.
• Use Dark Chocolate: Opt for dark chocolate to avoid an overly sweet taste. Dark chocolate adds depth and richness, balancing the overall sweetness and enhancing the chocolate flavor.
• Avoid Over-Baking: Monitor baking time closely and remove the bars when a toothpick inserted into the center comes out with a few moist crumbs. This prevents the bars from becoming dry and ensures a gooey, chewy texture.
• Cool Before Cutting: Allow the bars to cool completely in the pan before cutting. This helps them set and firm up, making it easier to achieve clean, even slices without crumbling.
• Avoid over mixing: Mix until just combined and then fold in the dark chocolate.
