Creating Brownie Mix Double Fudge Bars is one of my favorite ways to satisfy my sweet tooth. During a recent rainy afternoon, I decided to experiment with a box of brownie mix and add my twist to it. This method not only saves time but enhances the flavor with an extra layer of fudge that brings these bars to the next level!

I discovered that adding chocolate chips and a swirl of fudge before baking results in a chewy texture that complements the crispy edges perfectly. The bars are so versatile that you can even top them with nuts or a dusting of powdered sugar for serving!

Why You'll Love These Bars

  • Rich chocolate flavor paired with a decadent fudge layer
  • Quick and easy to prepare using a brownie mix
  • Perfect for sharing at parties or indulging alone

Baking with Brownie Mix

Using a box of brownie mix as the base for your Double Fudge Bars not only accelerates the process but also ensures consistent results every time. The pre-measured ingredients in the mix offer convenience without sacrificing flavor. Just remember that not all brownie mixes are created equal; some may have a higher cocoa content, which can substantially intensify the chocolate flavor. It’s worth experimenting with a few brands to find the one that delivers the richness you crave.

When preparing the batter, be careful not to overmix once you've combined the ingredients. Overmixing can lead to a denser texture, which may not yield the light and fudgy bars you desire. It's best to mix just until the dry ingredients are incorporated, leaving a few small lumps for a delightful final texture.

The Perfect Swirl

Drizzling fudge sauce on top of the batter adds both visual appeal and an extra layer of richness. To create an impressive swirl, use a knife or skewer to gently lift and combine the top layer with the batter beneath—this technique mixes the fudge evenly while maintaining distinct pockets of gooey goodness. If you prefer even more fudge flavor, you can double the fudge sauce and reserve some for drizzling on top once they’re baked and cooled.

For those who enjoy a little texture, consider adding crushed nuts or a sprinkle of sea salt atop the fudge drizzle. The salt enhances the chocolate flavor while providing a pleasant contrast to the sweetness. Just make sure to chop the nuts finely enough so they can be distributed evenly without overpowering each bite.

Serving and Storing

For the best texture, allow the brownie bars to cool completely before cutting them into squares. This waiting period is crucial as it helps the bars firm up just enough to hold their shape without crumbling. If you're in a hurry, you can refrigerate them for about 30 minutes, which also enhances their fudginess and makes for cleaner cuts.

If you're looking to make these bars ahead of time, they store excellently in an airtight container. They'll stay fresh for up to a week at room temperature or can be frozen for up to three months. Just make sure to place parchment paper between the layers if you stack them, preventing them from sticking together. When you're ready to enjoy them, let them thaw at room temperature for a few hours.

Ingredients

Gather the following ingredients to make these delicious Brownie Mix Double Fudge Bars:

Ingredients

  • 1 box of brownie mix
  • 1/2 cup vegetable oil
  • 1/4 cup water
  • 2 large eggs
  • 1 cup semi-sweet chocolate chips
  • 1/2 cup fudge sauce

Mix these ingredients well, and you're ready to bake!

Instructions

Follow these simple steps to bake your brownie bars:

Prepare The Batter

In a large mixing bowl, combine the brownie mix, vegetable oil, water, and eggs. Stir until just blended. Fold in the chocolate chips for extra richness.

Add To Baking Dish

Pour the brownie batter into a greased 9x13 inch baking dish. Use a spatula to spread it evenly. Drizzle fudge sauce over the top and use a knife to swirl it into the batter.

Bake

Preheat your oven to 350°F (175°C). Bake for 25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.

Cool and Serve

Allow the brownies to cool in the pan for at least 10 minutes before cutting them into bars. Enjoy!

Serve these bars warm or at room temperature, and watch them disappear!

Pro Tips

  • For a more intense flavor, consider adding a pinch of sea salt on top before baking.

Ingredient Substitutions

If you're looking to lighten up the recipe, you can substitute unsweetened applesauce for the vegetable oil. This swap not only reduces fat but also adds moisture, keeping the bars fudgy. Keep in mind, however, that the flavor may become slightly less rich, so consider adding an extra splash of vanilla extract for depth.

For those with dietary restrictions, opt for egg replacements like flaxseed meal or a commercial egg substitute. One flax egg can be made by mixing one tablespoon of ground flaxseed with two and a half tablespoons of water; let it sit until it thickens. This will help bind the ingredients while preserving the fudgy texture that makes these bars a favorite.

Variations to Consider

Feel free to get creative with mix-ins. You can fold in different types of chocolate chips such as dark chocolate or white chocolate for a unique twist. Dried fruit like cranberries or cherries can add a tart counterpoint to the sweetness. Just be mindful not to exceed the total amount of mix-ins beyond one cup, or the bars may not set properly.

Another fun variation is to turn these bars into a s'mores treat. Before baking, sprinkle mini marshmallows on top of the batter, allowing them to puff up and brown during baking. Once baked, you can drizzle additional fudge sauce over the marshmallows for an indulgent finish that brings nostalgic campfire flavors to your kitchen.

Absolutely! You can use milk chocolate or dark chocolate chips according to your preference.

→ How can I store the leftover brownies?
