These easy bars use a simple sugar cookie dough base, boosted with unsweetened cocoa and studded with mini chocolate chips — perfect for chocolate lovers and simple enough for everyday baking.

Classic sugar cookies are beloved for their buttery texture and vanilla aroma. Add cocoa powder and the result is a rich, chocolatey bar that still retains the soft, tender crumb you expect from sugar cookie dough.
Whether it’s your first time trying chocolate sugar cookie bars or you’re looking for a reliable version to bake again and again, this recipe delivers consistent results and straightforward steps.

Ingredients for this Chocolate sugar cookie bars recipe
Below are the ingredients used to make these bars. Exact measurements and a printable recipe card are included in the recipe section further down.
- Unsalted butter (melted and cooled): Melted butter makes the dough easy to press into the pan while keeping the bars tender. Use unsalted to control salt levels.
- Granulated sugar and brown sugar: Granulated sugar sweetens and adds structure; brown sugar brings moisture and a subtle caramel note that softens the bars.
- Large egg: Binds ingredients and contributes to structure.
- Vanilla extract: Enhances both the cookie base and the chocolate flavor.
- All-purpose flour: The foundation of the dough.
- Unsweetened cocoa powder: Provides the chocolate flavor — sifted for a smoother texture.
- Baking powder: A touch of leavening prevents the bars from becoming overly dense.
- Salt: Balances sweetness and sharpens chocolate notes.
- Mini chocolate chips: Optional but recommended for pockets of melty chocolate and added texture.

How to make this chocolate sugar cookie bars recipe
Follow these steps to turn sugar cookie dough into moist chocolate bars. Refer to the recipe card below for full ingredient amounts and timing.
- Preheat the oven to 350°F. Line an 8×8-inch square baking pan with parchment paper, leaving an overhang to lift the bars out easily.
- In a large bowl, beat the melted and cooled butter with the granulated and brown sugars until combined. Add the egg and vanilla extract, mixing until smooth.
- In a separate bowl, whisk together the flour, unsweetened cocoa powder, baking powder, and salt.
- Gradually add the dry ingredients to the wet, mixing until a dough forms. Scrape the bowl sides to incorporate all the dry bits.
- Press the dough evenly into the prepared pan using your hands or an offset spatula. Scatter the mini chocolate chips over the top and gently press them in.
- Bake until the edges are set and a toothpick inserted into the center comes out with a few moist crumbs, about 20–25 minutes.
- Let the bars cool completely in the pan before lifting them out and slicing into squares. Cooling fully ensures clean slices and the best texture.

Frequently Asked Questions – FAQ
How do I store leftover bars?
Store cooled bars at room temperature in a sealed container or a resealable bag for 3–4 days. For longer freshness, refrigerate in an airtight container for up to 7–9 days. For extended storage, wrap bars individually in plastic wrap, place them in an airtight container or freezer bag, and freeze for several months. Wrapping first prevents freezer burn and preserves flavor.

Can I add a chocolate frosting to this chocolate sugar cookie bars recipe?
Yes. A simple chocolate frosting can be made with butter, cocoa powder, powdered sugar, and a splash of milk or cream. For a richer, tangier topping, fold in some cream cheese. Frosting adds extra decadence and works well if you plan to serve these bars for a celebration.

Can I try different flavors with this recipe?
Absolutely. The dough is versatile — try these variations:
- Swap mini chocolate chips for white chocolate or peanut butter chips.
- Add a few drops of peppermint extract for chocolate-mint bars.
- Stir in a small amount of espresso powder to emphasize the chocolate with a mocha note.
Can I double this recipe?
Yes. To double the recipe, bake it in a 9×13-inch pan and increase the bake time by a few minutes. Check doneness with a toothpick—when it comes out with a few moist crumbs, the bars are ready.
