Creating Brownie Mix Double Fudge Bars has become a staple in my kitchen. The ease of using a pre-made mix allows for maximum flavor without the hassle, and I’ve learned that adding chocolate chips really enhances the depth of chocolate in each bite. I've also found that letting the bars cool completely before cutting makes for cleaner edges and a more presentable dessert.

One particular time, I decided to sprinkle sea salt on top before baking, and it was a game changer! The salty sweetness combined beautifully with the fudge, adding an extra layer of flavor that I highly recommend to everyone trying this recipe. This simple addition made these bars a hit!

Creating the Perfect Brownie Base

The foundation of these Brownie Mix Double Fudge Bars is the brownie mix itself, which provides convenience and a consistent texture. When mixing, ensure all ingredients are well-combined until the batter appears uniform, without streaks of dry mix. This step is crucial for achieving the fudgy texture you desire. Over-mixing can lead to cake-like brownies instead of the dense, rich bars you want, so mix just until incorporated.

Using chocolate chips not only adds extra chocolate flavor but also contributes to the fudginess of the bars. I recommend using semi-sweet chocolate chips for their perfect balance of sweetness and richness. If you desire a more intense chocolate experience, consider using dark chocolate chips or a mix of both semi-sweet and dark. This will elevate the taste and make every bite even more decadent.

Tips for Baking Success

When pouring your brownie batter into the prepared pan, take a moment to spread it evenly using a spatula. This ensures that the bars cook uniformly and prevents any overcooked edges while keeping the center moist. I often find that lightly tapping the pan on the counter after pouring helps remove any air bubbles that might have formed, leading to a better texture in the final product.

Baking time can vary based on your oven, so be sure to check for doneness a couple of minutes before the recommended 25 minutes. Insert a toothpick into the center; it should come out with a few moist crumbs attached, not completely clean. This indicates your bars are perfectly fudgy. If you overbake, they can become dry, so keep a close eye on them as they approach the end of the baking time.

Ingredients

1/2 cup vegetable oil

Instructions

Preheat the Oven

Preheat your oven to 350°F (175°C) and grease a 9x9 inch baking pan.

Mix the Ingredients

In a large bowl, combine the brownie mix, vegetable oil, and eggs. Mix until smooth and then fold in the chocolate chips.

Pour and Bake

Pour the batter into the prepared baking pan, spreading it evenly. If desired, sprinkle sea salt or nuts on top. Bake for 25 minutes or until a toothpick comes out with moist crumbs.

Cool and Cut

Let the brownies cool completely in the pan for best results. Once cool, cut into 16 bars and serve.

Enjoy with ice cream or as is for a perfect treat!

Pro Tips

For an added layer of flavor, try adding a teaspoon of vanilla extract to the brownie batter. If you love your brownies extra fudgy, bake them for a minute less than instructed.

Serving Suggestions

These Brownie Mix Double Fudge Bars can be served warm or cooled, depending on your preference. To capture that warm, gooey texture, serve them more immediately after baking alongside a scoop of vanilla ice cream. The contrast of hot brownie and cold ice cream creates a delightful taste experience that is hard to resist.

For a more sophisticated dessert presentation, consider dusting the cooled bars with powdered sugar or serving them with fresh berries. This not only adds a pop of color but also brings a touch of freshness that balances the rich chocolate flavor beautifully.

Storage and Make-Ahead Options

These brownies can be stored in an airtight container at room temperature for up to three days. If you want to keep them longer, freeze them for up to three months. To freeze, wrap each bar individually in plastic wrap, then place them in a freezer-safe bag. This prevents freezer burn and helps maintain their rich taste and texture.

To thaw frozen bars, simply leave them at room temperature for a few hours or reheat them in the microwave for about 15-20 seconds for that freshly baked feel. This method ensures you can enjoy your delicious dessert over an extended period without sacrificing quality.
