Classic Chocolate Dessert Bars That Never Disappoint

Some treats are so simple, so rich, and so reliably delicious that you’ll want to keep the recipe taped to your fridge.

Chocolate dessert bars are that kind of dessert. They combine the chew of brownies, the softness of cake, and the boldness of cocoa into one finger-friendly slice.

Start with a cocoa-rich base — I prefer using unsweetened cocoa powder along with melted butter for a deep, velvety flavor.

The batter comes together in one bowl and needs no mixer, just a sturdy spoon and some patience. After baking, the top forms a crackly crust while the middle stays fudgy.

You can add chopped chocolate, nuts, or a swirl of peanut butter for a personal touch.

Chill them for neat cuts or serve warm with a scoop of ice cream — there’s really no wrong way to enjoy them.

How to Make Chocolate Dessert Bars

These bars are simple to mix, quick to bake, and perfect to chill or serve warm. Here’s how to make them step by step:

---

Step 1: Prep and Preheat

Preheat your oven to 350°F (175°C). Line your baking pan with parchment paper, leaving some overhang for easy lifting later.

---

Step 2: Mix Wet Ingredients

In a large mixing bowl, combine melted butter, granulated sugar, and brown sugar. Whisk until smooth.

Add eggs and vanilla extract, and whisk again until fully combined and glossy.

---

Step 3: Add Dry Ingredients

Sift in the flour and cocoa powder. Stir gently with a spatula or wooden spoon until no dry patches remain.

Fold in the chocolate chips or chunks at the end.

---

Step 4: Bake to Perfection

Pour the batter into the prepared pan and smooth the top.

Bake for 20–25 minutes or until the edges are set and a toothpick in the center comes out with a few moist crumbs.

---

Step 5: Cool and Slice

Let the bars cool in the pan for 15 minutes, then transfer to a wire rack to cool completely.

Once cooled, slice into neat squares using a sharp knife.
