Step-by-step instructions
Preheat the oven to 350°F (175°C). Grease a 9×13 inch baking pan generously.
In a large bowl, whisk together the melted butter and brown sugar until smooth and no longer warm.
Beat in the eggs one by one, making sure to fully incorporate each before adding the next. Add the vanilla extract as well.
In another bowl, whisk together the flour, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture. Mix until just combined—avoid overmixing!
Fold in the semi-sweet chocolate chips and optional nuts. You’ll notice the batter is thick and luscious.
Spread the batter evenly into the prepared baking pan.
Bake for 25–30 minutes until the top turns a golden brown. The center should still be slightly soft when you test it.
Let the Congo Bars cool completely in the pan to set before cutting into squares.
Best ways to enjoy it
Congo Bars are delicious right out of the pan, but you can elevate your serving game with a few ideas:
- Serve them warm with a scoop of vanilla ice cream for an irresistible dessert.
- Top with whipped cream and fresh strawberries for a berry twist.
- Drizzle with caramel or chocolate sauce to take the flavor up a notch.
Storage and reheating tips
To keep your Congo Bars fresh for as long as possible, store them in an airtight container at room temperature. They’ll stay good for about a week. If you have leftovers or want to save some for later, feel free to freeze them! Just wrap them tightly in plastic wrap or foil and store them in a freezer-safe container. When ready to enjoy, simply thaw at room temperature or pop them in the microwave for a few seconds to rewarm.
Helpful cooking tips
- Make sure your eggs are at room temperature to achieve the best mix.
- Don’t rush the cooling process; it helps the bars set properly for cleaner cuts.
- Experiment with add-ins! Try swapping out chocolate chips for butterscotch or peanut butter chips for a fun twist.
Creative twists
While the classic recipe is a hit, consider these variations to mix things up:
- Nut-Free: Simply omit the nuts for a nut-free version that still tastes amazing.
- Flavored Congo Bars: Add a teaspoon of almond extract or espresso powder to the batter for extra flavor depth.
- Healthier Options: Replace half of the all-purpose flour with whole wheat flour for added nutrition without sacrificing texture.
