The Best Espresso Brownie Cookie Sandwiches Ingredients
For the Brownie Cookies
• Dark Chocolate (7 oz) – Provides rich, deep chocolate flavor—use semisweet chocolate if preferred.
• Unsalted Butter (6 tbsp) – Adds moisture and richness; you can use salted butter but reduce added salt.
• Brown Sugar (¾ cup) / Granulated Sugar (¼ cup) – Contributes sweetness and moisture; try coconut sugar for a healthier option.
• Large Eggs (2) – Acts as a binder; no substitutes for texture!
• All-Purpose Flour (¾ cup) – Offers structure to cookies; a gluten-free blend works too.
• Dutch-Processed Cocoa Powder (¼ cup) – Intensifies chocolate flavor; swap with natural cocoa for a different taste.
• Salt (¼ tsp for cookies) – Balances sweetness and brings out flavors.
For the Espresso Buttercream
• Powdered Sugar (1½ cups) – Main ingredient for smooth frosting; avoid substitutions to maintain texture.
• Espresso Powder (2 tbsp) – Infuses lovely coffee flavor into frosting; instant coffee can substitute but will be less intense.
• Vanilla Bean Paste (1 tsp) – Adds aromatic flavor; you can switch to pure vanilla extract if needed.
• Heavy Cream (1 tbsp) – Use to thin buttercream if too thick; omit if consistency is just right.

How to Make The Best Espresso Brownie Cookie Sandwiches
-
Preheat and Prepare: Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper to ensure easy cookie removal.
-
Melt Chocolate and Butter: In a small saucepan, melt the dark chocolate and unsalted butter over low heat. Stir until smooth, then allow the mixture to cool slightly before using.
-
Mix Wet Ingredients: In a mixer, combine the brown sugar, granulated sugar, and large eggs. Beat on high until the mixture is pale and fluffy, about 3 minutes. Then, add your cooled chocolate mixture and mix well.

Scoop and Bake: Using a cookie scoop, drop dough onto your prepared baking sheets, spacing them about 2 inches apart. Bake for 10 minutes, or until the edges are set and the centers are still gooey.
-
Cool Cookies: Let the cookies cool on a wire rack for better texture and to allow them to firm up slightly.

Expert Tips for The Best Espresso Brownie Cookie Sandwiches
-
Melt Ingredients Gently: Always melt the chocolate and butter over low heat. High temperatures can cause chocolate to seize, ruining your cookies.
-
Don’t Overmix: When combining dry and wet ingredients, mix just until incorporated. Overmixing can lead to tough cookies instead of soft, fudgy ones.
-
Cool Properly: Allow cookies to cool on a wire rack to ensure even texture. Cooling in a pan can trap steam and make them less chewy.
-
Frosting Consistency: If the buttercream is too thick, add heavy cream gradually until you reach your desired thickness. Proper consistency is key for easy spreading.
-
Adjust Baking Time: For perfect gooeyness, slightly underbake your cookies. They should look set but still soft in the middle.
-
Storage Tips: Store the Best Espresso Brownie Cookie Sandwiches in an airtight container at room temperature for up to 3 days to maintain freshness.

The Best Espresso Brownie Cookie Sandwiches Recipe FAQs
What type of chocolate is best for making the cookies?
I recommend using dark chocolate (at least 60% cocoa) for a rich flavor, but you can opt for semisweet chocolate if you prefer a sweeter profile. The dark chocolate enhances the depth of the brownie cookies, while semisweet will offer a milder taste.
How should I store my cookie sandwiches?
You can store the Best Espresso Brownie Cookie Sandwiches in an airtight container at room temperature for up to 3 days. If you want them to last longer, refrigerate them for up to a week or freeze them individually for up to 1 month. Just wrap each sandwich in plastic wrap, then keep them in a freezer-safe bag.
Can I freeze the baked cookies before assembling the sandwiches?
Absolutely! To freeze the brownie cookies, let them cool completely, then wrap them individually in plastic wrap and place them in a freezer-safe bag. They can be frozen for up to 3 months. When you’re ready to enjoy them, simply thaw at room temperature and use the buttercream to assemble the sandwiches.
What should I do if my cookies turn out too hard?
If your cookies come out harder than desired, they might have been overbaked. For future batches, keep a close eye on them in the oven; they should look set around the edges but still soft in the center. Also, consider lowering the baking time by a minute or two to ensure the gooey texture.
Are there any common allergens in this recipe?
Yes, this recipe contains common allergens such as eggs, gluten (in all-purpose flour), and dairy (in butter and heavy cream). If you’re accommodating allergies, you can use egg substitutes and gluten-free flour blends. However, these changes might affect the overall texture and taste.
What is the best way to ensure my buttercream is smooth and creamy?
Begin by beating the butter until it’s light and fluffy before gradually mixing in the powdered sugar. It’s crucial to add espresso powder and any liquid (like heavy cream) slowly, mixing well in between. If your frosting becomes too thick, add heavy cream by the tablespoon until you achieve the desired spreading consistency.
