Step-by-Step Instructions to Make Brownie Cookie Sandwich

1. Prepare the Oven and Baking Trays

Preheat your oven to 350°F (180°C) and line two baking trays with parchment paper.

2. Melt the Butter and Chocolate

  • In a saucepan, bring 1 inch of water to a simmer. Place a heatproof bowl over the simmering water, ensuring it doesn’t touch the water.
  • Add the butter and 10 oz of chocolate chips to the bowl. Stir until melted and smooth.

3. Mix the Eggs, Cocoa Powder, and Sugar

  • In a separate bowl, beat the eggs, cocoa powder, and caster sugar on high speed for 3 minutes. Use a stand mixer with a whisk attachment or an electric hand mixer.

4. Combine the Wet Ingredients

  • Gradually pour ⅓ of the melted chocolate mixture into the egg mixture and mix well.
  • Add the remaining chocolate mixture and stir until fully combined.

5. Add Dry Ingredients

  • Mix in the vanilla extract, salt, and baking powder.
  • Slowly fold in the flour until just combined—be careful not to overmix.
  • Gently stir in the remaining ½ cup of chocolate chips.

6. Scoop and Bake

  • Drop 2-tablespoon mounds of batter onto the baking trays, leaving 2 inches between each cookie. For smaller cookies, use 1 tablespoon of batter per mound.
  • Bake large cookies for 15–20 minutes or smaller ones for 10–15 minutes. Adjust the baking time based on your preference for soft or firm cookies.
  • Let the cookies cool on the tray for 5–10 minutes before transferring them to a rack.

7. Make the Peanut Butter Frosting

  • Combine peanut butter, confectioners’ sugar, softened butter, vanilla extract, and salt in a mixing bowl.
  • Beat on high speed for 5 minutes until the mixture becomes creamy.
  • Add the heavy cream and continue beating for 2 more minutes until fluffy.

8. Assemble the Brownie Cookie Sandwich

  • Spread a generous layer of peanut butter frosting on the flat side of one cookie.
  • Place another cookie on top to create a sandwich.
  • Repeat with the remaining cookies and frosting.

Tips for Perfect Brownie Cookie Sandwiches

1. Use High-Quality Chocolate

The flavor of your cookies depends heavily on the quality of the chocolate. Opt for a rich, dark chocolate for the best results.

2. Avoid Overbaking

Brownie cookies should have a slightly soft and fudgy center. Keep an eye on them during baking to ensure they don’t become too crisp.

3. Chill the Frosting

If your frosting feels too soft to work with, chill it in the refrigerator for 10–15 minutes before assembling the sandwiches.

Variations to Try

1. Nutty Twist

Add chopped nuts like pecans, walnuts, or hazelnuts to the cookie batter for added crunch.

2. Chocolate Overload

Dip the assembled cookie sandwiches in melted chocolate and let them set for an extra indulgent treat.

3. Flavored Frosting

Experiment with flavored frostings, like a chocolate ganache or cream cheese filling, for a unique twist.
