Step‑by‑Step Instructions for Brownie Cookie Dough Sandwich Cookies
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). While the oven warms up, line two baking sheets with parchment paper. This will help the cookies bake evenly and prevent them from sticking. It’s crucial to have everything prepared so the cookies can go right into the oven once your dough is ready.
Step 2: Melt the Chocolate and Butter
In a microwave-safe bowl, combine the semisweet chocolate chips and unsalted butter. Heat them in the microwave in 30-second intervals until melted, stirring after each interval for a smooth consistency. Once melted and silky, let the mixture cool slightly; this step is essential to avoid curdling the eggs in the next step.
Step 3: Whisk the Eggs and Sugar
In a separate large mixing bowl, beat together the eggs, granulated sugar, and vanilla extract using a hand mixer or whisk. Continue mixing until the mixture becomes thick and pale, which should take about 3-5 minutes. The aeration from mixing will help create a lighter texture for your brownie cookies.
Step 4: Combine Chocolate Mixture with Egg Mixture
Gently fold the cooled chocolate and butter mixture into the egg and sugar mixture. Use a spatula to combine the two mixtures carefully, ensuring you maintain the airiness created in the eggs. This rich chocolatey blend will form the base for your delicious Brownie Cookie Dough Sandwich Cookies.
Step 5: Mix Dry Ingredients
In another bowl, whisk together the all-purpose flour, baking powder, and salt to combine. This step ensures that your baking powder is evenly distributed. Carefully fold this dry mixture into the chocolate mixture until just combined; over-mixing can lead to tough cookies, so stop once you see no dry flour.
Step 6: Scoop the Cookie Dough
Using a rounded spoon or cookie scoop, drop heaping spoonfuls of dough onto the lined baking sheets, spacing them about two inches apart. Be generous with your scoops; these treats deserve to be hearty! The dough will spread slightly while baking to create that perfect chewy texture.
Step 7: Bake the Cookies
Place the baking sheets in the preheated oven and bake for 8 to 10 minutes. Keep an eye on them; they should appear set and slightly cracked on the tops when done. Once baked, take them out and let the cookies cool on the baking sheets for a few minutes before transferring them onto a wire rack.
Step 8: Prepare the Cookie Dough Filling
While your cookies cool, prepare the creamy cookie dough filling. In a mixing bowl, beat together softened butter, brown sugar, and granulated sugar until creamy and fluffy. This process should take about 2-3 minutes and will give your filling that delightful, smooth texture.
Step 9: Mix in Milk and Vanilla
Add the milk and vanilla extract to the sugar mixture. Mix well until the filling is smooth and velvety. If you prefer a thicker filling, you can adjust the milk amount slightly. The cookie dough filling will provide that indulgent contrast to the fudgy brownie cookies, enhancing your sandwich cookies’ irresistible taste.
Step 10: Fold in Flour and Chocolate Chips
Gradually stir in the all-purpose flour and a pinch of salt into the filling mixture, ensuring it incorporates fully. Then, gently fold in the mini chocolate chips, which will add delightful bursts of flavor in every bite. This cookie dough mixture is safe to eat, making it a delicious finale to your Brownie Cookie Dough Sandwich Cookies.
Step 11: Assemble the Sandwich Cookies
Take one cooled brownie cookie and spread or pipe about one tablespoon of the cookie dough filling onto its flat side. Top with another brownie cookie, pressing gently to create a sandwich. This assembly creates a beautiful balance of textures and flavors that you and your loved ones will enjoy.
Step 12: Repeat and Store
Continue assembling the remaining cookies with the filling. Once completed, store the assembled Brownie Cookie Dough Sandwich Cookies in an airtight container at room temperature for up to three days, or refrigerate for a lasting treat. These cookies are perfect for any occasion or just a sweet indulgence anytime!

How should I store the assembled brownie cookie dough sandwich cookies?
For optimal freshness, keep your assembled cookies in an airtight container at room temperature for up to 3 days.

Can I freeze brownie cookie dough sandwich cookies? If so, how?

What should I do if my brownie cookies spread too much during baking?
Very good question! If you find your cookies are spreading excessively, double-check your flour measurements to ensure you’ve used enough.

Additionally, using a kitchen scale may help you achieve precise measurements and yield the best results.
Are these brownie cookie dough sandwich cookies safe for people with egg allergies?
No problem at all! You can easily make these cookies egg-free by substituting the eggs with flax eggs. To create a flax egg, simply mix 1 tablespoon of ground flaxseed with 2.5 tablespoons of water.

How can I make the filling thicker?
If you prefer a thicker cookie dough filling, simply adjust the amount of milk you use.
