  • Versatile as a snack, dessert, or even breakfast option

Ingredients

  • Butter: Unsalted butter adds richness and contributes to the tender, moist texture of the bars.
  • Granulated sugar: Provides sweetness and helps create a slight crispness on the edges.
  • Brown sugar: Adds moisture and a subtle caramel flavor for deeper sweetness.
  • Egg: Acts as a binder and gives structure to the cookie bars.
  • Vanilla extract: Enhances overall flavor with a warm, aromatic essence.
  • All-purpose flour: The main dry ingredient that gives body and structure to the bars.
  • Baking soda: Leavens the dough, helping the cookie bars rise slightly and become soft.
  • Salt: Balances sweetness and enhances the overall flavor profile.
  • Chocolate chips: Generous semi-sweet chips add bursts of melty chocolate throughout the bars.

Instructions

Preheat the oven and prepare the pan

Set your oven to 350°F (175°C) and grease a 9×13-inch baking pan or line it with parchment paper. This ensures the cookie bars bake evenly and don’t stick to the pan.

Cream the butter and sugars

In a large mixing bowl, beat softened butter with granulated and brown sugar until the mixture is light, fluffy, and pale in color. This step aerates the base to create a tender texture in the finished bars.

Add egg and vanilla extract

Mix in the egg followed by the vanilla extract, ensuring they are fully incorporated for uniform flavor and proper binding of the ingredients.

Combine dry ingredients

In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This helps to evenly distribute the leavening agent and salt throughout the dough.

Mix dry ingredients into wet mixture

Gradually add the dry flour mixture to the wet butter mixture, mixing just until combined to avoid overworking the dough, which could result in tougher bars.

Fold in chocolate chips

Gently fold in the chocolate chips, distributing them evenly throughout the dough to ensure every bite has melty chocolate goodness.

Transfer batter and bake

Spread the dough evenly into the prepared baking pan, smoothing the top. Bake in the preheated oven for 25-30 minutes or until the edges are golden brown and a toothpick inserted comes out with moist crumbs.

Cool before slicing

Allow the cookie bars to cool completely in the pan on a wire rack. Cooling helps them set so they slice cleanly without crumbling apart.

You Must Know

  • Do not overmix your dough to keep cookie bars tender and moist rather than dense.
  • Butter should be softened but not melted for proper creaming with sugars.
  • Cooling fully before cutting prevents the chocolate from melting all over your fingers.

Storage Tips

Store the cookie bars in an airtight container at room temperature for up to 4 days. For longer storage, freeze individually wrapped bars for up to 3 months, thawing before serving.

Serving Suggestions

Serve these bars warm with a scoop of vanilla ice cream for an indulgent dessert. They are also delicious paired with a glass of cold milk or a hot cup of coffee or tea.

Professional Tips

  • Use room temperature ingredients for better mixing and consistent texture.
  • For extra gooeyness, slightly underbake the bars by a couple of minutes.
  • Mix in nuts or substitute half the chocolate chips with white or dark chocolate for a flavor twist.

FAQs

Can I use salted butter instead of unsalted?

Yes, but reduce or omit added salt in the recipe to balance flavor.

How do I make these cookie bars gluten-free?

Substitute all-purpose flour with a gluten-free baking blend that measures like regular flour.

Can I add nuts to the recipe?

Absolutely! Walnuts or pecans chopped and folded in add delightful crunch and flavor.

Can I use different types of chocolate chips?

Yes, mix semisweet, milk, white, or dark chocolate chips according to your preference.

What is the best way to cut the bars without crumbling?

Allow them to cool completely before slicing with a sharp knife for clean edges.
