Introduction

These Best Brown Butter Coffee Toffee Cookies with Sea Salt Topping combine rich, nutty brown butter with bold coffee flavor and sweet toffee bits. A touch of sea salt on top balances the sweetness perfectly, making these cookies irresistible for any snack or dessert.

The image shows several round cookies placed on a wooden surface with a white marbled texture added in the background. Each cookie has a thick, golden-brown outer layer that is cracked and textured like oatmeal or peanut butter cookie dough. The center of the cookie is a smooth, light brown layer filled with shiny caramel dollops arranged around the middle. The very top of the caramel center is sprinkled with coarse white sea salt, adding a contrast in color and a grainy texture. The cookies are slightly raised and thick, giving them a soft and chewy look, and steam rises gently from them, making them appear freshly baked. photo taken with an iphone --ar 4:5 --v 7

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 instant coffee granules in 1 tablespoon of hot water. 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 until it turns golden brown, about 5 to 7 minutes. Stir in both sugars until combined. Remove from heat and let cool for 5 minutes.
Step 5: Add eggs one at a time to the butter mixture, 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.
Step 7: Using a cookie scoop or spoon, drop rounded dough balls onto the prepared baking sheet, spacing them about 2 inches apart.
Step 8: Bake for 9 to 11 minutes, or until the edges are golden brown. Remove from oven and immediately sprinkle with sea salt. Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Tips & Variations

For a stronger coffee flavor, add an extra teaspoon of instant coffee or use espresso powder instead.
Try mixing in chopped nuts like pecans or walnuts for extra crunch.
Use dark chocolate chunks instead of toffee bits for a rich chocolate-coffee twist.

Storage

Store cooled cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze the cookies in a sealed container for up to 3 months. Reheat briefly in a warm oven to refresh the texture and flavor.

How to Serve

FAQs

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

Instant coffee granules dissolve easily and concentrate the flavor, so they work best. Using brewed coffee may add too much liquid to the dough and affect texture.
