Ingredients

2 1/4 cups all-purpose flour
2 tablespoons instant coffee granules
1 teaspoon baking soda
1/2 teaspoon salt
1 cup unsalted butter
3/4 cup dark brown sugar
1/2 cup granulated sugar
2 large eggs
2 teaspoons vanilla extract
1 1/2 cups toffee bits
Sea salt, for sprinkling

Instructions

Step 1: Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
Step 2: In a small bowl, dissolve the instant coffee granules in 1 tablespoon of hot water and set aside.
Step 3: In a large bowl, whisk together the flour, baking soda, and salt. Set aside.
Step 4: In a saucepan over medium heat, melt the butter and continue cooking, stirring frequently, until it turns golden brown and smells nutty, about 5-7 minutes. Remove from heat and stir in both sugars until combined. Let cool for 5 minutes.
Step 5: Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract and dissolved coffee.
Step 6: Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Fold in the toffee bits gently.
Step 7: Using a cookie scoop or spoon, drop rounded balls of dough onto the prepared baking sheet about 2 inches apart.
Step 8: Bake for 9-11 minutes or until the cookie edges are golden brown. Remove from the oven and immediately sprinkle with a pinch of sea salt. Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Tips & Variations

Use a high-quality instant coffee for the best flavor, or try espresso granules for a stronger coffee taste.
For a chocolatey twist, add 1/2 cup of chocolate chips along with the toffee bits.
Make sure not to overmix the dough after adding the flour to keep cookies tender and chewy.
Brown the butter slowly to avoid burning and to bring out the deep nutty flavor.

Storage

Store cookies in an airtight container at room temperature for up to 5 days. To keep them fresh longer, refrigerate for up to 2 weeks. If desired, warm the cookies briefly in the microwave before serving to restore their softness and enhance the toffee flavor.

How to Serve

On top of the center, there are dollops of shiny caramel arranged evenly around the edge, accented by small white coarse salt flakes sprinkled in the middle. The cookies have a soft, crumbly texture with visible cracks. Steam gently rises from the cookies, giving a warm, fresh-baked feel. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use regular brewed coffee instead of instant coffee granules?

Instant coffee granules dissolve easily and provide concentrated flavor, so it’s best to use them. Using brewed coffee may alter the dough’s moisture content and affect texture.

How do I prevent the toffee bits from melting during baking?

Choosing sturdy, good-quality toffee bits helps them hold their shape. Also, mixing them gently into the dough and baking at the recommended temperature reduces excessive melting.
