How to Make Brownie Cookie Sandwiches
-
Preheat Oven: Begin by preheating your oven to 350°F (175°C). Don’t forget to line two baking sheets with parchment paper for easy cookie transfer!
-
Mix Cookie Dough: In a large bowl, whisk together the melted unsalted butter and granulated sugar until the mixture is smooth and creamy. Add in the eggs and vanilla extract, mixing well. Gradually incorporate the cocoa powder, flour, salt, and baking soda until you’ve formed a thick, luscious batter. Fold in those scrumptious semi-sweet chocolate chips for an extra chocolaty delight!
-
Shape Cookies: Using a tablespoon, scoop portions of cookie dough onto your prepared baking sheets, spacing them about 2 inches apart. Give each ball a gentle press to slightly flatten them for even baking.
-
Bake: Place the trays in the oven and bake for 10-12 minutes. You’ll know they’re ready when the edges are set but the centers are still soft. Allow them to cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.
-
Prepare Buttercream: While the cookies cool, grab another bowl and beat together the softened butter, brown sugar, and powdered sugar until the mixture is light and fluffy. Add the vanilla extract and milk, mixing until creamy. Finally, fold in mini chocolate chips for that irresistible cookie dough vibe!
-
Assemble: Once the cookies are completely cool, take one cookie and spread a generous layer of cookie dough buttercream on its flat side. Sandwich it with another cookie, gently pressing down. Repeat this delightful process with the remaining cookies.
Optional: Sprinkle a little sea salt on top of the buttercream for an added flavor kick!

Brownie Cookie Sandwiches with Cookie Dough Buttercream Recipe FAQs
What type of chocolate should I use for the brownie cookies?
Absolutely! I recommend using semi-sweet chocolate chips for that classic chocolatey flavor. However, feel free to swap them for dark chocolate if you prefer a richer taste or milk chocolate for a sweeter bite.
How should I store my brownie cookie sandwiches?
To keep your brownies fresh, place them in an airtight container at room temperature for up to 1 day. If you’d like them to last longer, store them in the refrigerator for up to 5 days or freeze them for up to 2 months. Just make sure to wrap them individually and keep them in a freezer-safe bag.
Can I make these brownie cookie sandwiches vegan?
Very much so! To create a vegan version, simply substitute the large eggs with flaxseed meal. For each egg, mix 1 tablespoon of flaxseed meal with 2.5 tablespoons of water and let it sit for a few minutes to thicken before adding it to the batter. You can also use plant-based butter and non-dairy milk for the buttercream.
How do I know when my cookies are done baking?
The trick is to watch the edges! Bake until the edges are set but the centers still look a bit soft, which usually takes about 10-12 minutes. If your cookies appear to have dark spots all over, that’s a sign they may be overbaked. They should be soft to the touch when you pull them out; they’ll continue to firm up as they cool.
What’s the best way to freeze brownie cookie sandwiches?
To freeze your brownie cookie sandwiches, wrap each one individually in plastic wrap to prevent freezer burn, then place them in a labeled and dated freezer-safe zip-top bag. They’ll keep well frozen for up to 2 months. When you’re ready to enjoy them, allow them to thaw at room temperature for about 30 minutes or warm them briefly in the microwave for that freshly-baked sensation.
What can I use instead of unsalted butter in the buttercream?
If you’re looking for a substitute, coconut oil or vegan buttery spreads can work wonderfully in the buttercream. Just ensure they are softened to make it easy to whip them until light and fluffy. This way, you can enjoy the same creamy texture without dairy!
