Coffee Cookie Crack Bars

These Coffee Cookie Crack Bars are the sort of bake that instantly elevates any snack table or afternoon coffee break. Rich and buttery with deep coffee flavor, a gooey condensed milk topping, and a shower of sea salt, they strike that perfect note of sweet meets sophisticated. I have taken these to every potluck and holiday get-together for years and they disappear before anything else does.

I still remember the first batch I brought to my book club everyone demanded the recipe and now I always double the batch to keep up with requests

• Unsalted butter: room temperature This creates a tender crumb and rich flavor Look for butter with just cream and no additives for best results
• Dark brown sugar: brings out the caramel notes in the bar Make sure it is packed well for accurate measuring
• All purpose flour: gives these bars their structure Sift or spoon and level for the right texture
• Milk chocolate chips: add creamy bursts of chocolate throughout Use good quality chips for best melt and flavor
• Instant coffee granules: infuses every bite with deep roast flavor I always use specialty instant coffee from the grocery store for the best taste
• Baking powder: ensures the bars rise and stay tender Check that yours is fresh and not expired
• Salt: balances the sweetness and elevates all the flavors Use fine salt in the dough
• Vanilla extract: enhances every layer look for pure extract for true vanilla flavor
• Espresso powder (optional): but extra punchy Choose a trusted brand for real coffee flavor if you want even more depth
• Sweetened condensed milk: creates that signature gooey topping Choose a name brand for consistency
• More unsalted butter: for richness in the glaze
• Vanilla extract: added to the topping for a warm finish
• Flaky sea salt: sprinkled over the top for textural magic Maldon or another high quality flake is best

Step-by-Step Instructions

Cream the Butter and Sugar:

Beat room temperature butter and brown sugar with a stand or hand mixer for two to three minutes The mixture should look pale and fluffy This step adds air and gives you a lighter cookie base

Add and Mix Dry Ingredients:

Add flour chocolate chips instant coffee baking powder salt vanilla and optional espresso powder Mix on medium speed just until combined The mixture may appear crumbly but if you pinch it together it should hold its shape

Press Into Pan:

Transfer the dough to a lined nine by thirteen inch baking dish Use your hands or the back of a measuring cup to press it down into an even layer

Bake the Cookie Layer:

Place the pan in a three hundred fifty degree Fahrenheit oven and bake for twenty minutes The edges should look set but the middle will remain soft

Prepare the Condensed Milk Topping:

While the bars bake heat condensed milk and unsalted butter in a saucepan on low Stir every minute or so until the mixture looks thick glossy and perfectly smooth Remove from heat and quickly stir in vanilla extract

Add the Creamy Layer and Bake Again:

As soon as the cookie layer comes out pour the warm condensed milk mixture evenly over the top Return the pan to the oven and bake for another ten to fifteen minutes until the topping is bubbling

Finish with Flaky Sea Salt and Cool:

Remove from oven and immediately sprinkle with flaky sea salt Let the bars cool at least thirty minutes to one hour longer if possible to allow the topping to set Slip the pan into the fridge or even freezer to speed it up if you like

Cut and Serve:

Once fully cooled slice into bars and enjoy Store leftovers in the fridge or freezer for best texture I find these are most irresistible on day two and three

I will never forget baking these with my mom and my daughter and watching three generations crowd around the kitchen counter for that very first taste The way the kitchen smells when this bakes is reason enough to make it again and again

Storage Tips

Once you have cut the bars arrange them in a single layer inside an airtight container Separate layers with parchment to prevent sticking Always refrigerate or freeze to preserve the gooey topping If you want that melty chocolate effect gently zap a bar in the microwave for a few seconds before eating They are also fantastic frozen for an ice cold treat in summer

Ingredient Substitutions

You can swap out the milk chocolate chips for dark or semisweet chips for a more pronounced cocoa flavor Oat flour works well for a gluten free version just measure lightly If you do not have espresso powder double up on instant coffee or omit altogether For a nutty crunch stir in a half cup of chopped pecans with the dough

Serving Suggestions

These bars shine at the end of a dinner party piled high on a vintage cake stand You can pair them with strong coffee or pour a splash of cream over them for a twist Serve them chilled for a more fudge like bite or try warming them and topping with a scoop of vanilla ice cream They make a decadent brunch addition next to a big pot of coffee and fresh berries

Cultural Note

Coffee and chocolate have a long history together in desserts especially in European and Middle Eastern baking traditions These bars are a modern spin on classic millionaire shortbread with the lively kick of coffee and the snappy finish of sea salt They will remind you of your favorite coffee shop treat or bakery slice but one hundred percent homemade
