Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your cake bakes evenly and rises beautifully.
Step 2: Prepare the Baking Pan
Grease a 9×13 inch baking pan with butter or non-stick spray. For added security, line the bottom with parchment paper to prevent sticking.
Step 3: Mix Dry Ingredients
In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt until well combined.
Step 4: Combine Wet Ingredients
In another bowl, beat the eggs, milk, vegetable oil, and vanilla extract until smooth.
Step 5: Combine Wet and Dry Mixtures
Gradually add the wet ingredients to the dry ingredients, mixing until just combined. Be careful not to overmix; a few lumps are okay!
Step 6: Add Boiling Water
Stir in the boiling water. This step may seem unusual, but it creates a moist cake. The batter will be thin, but that’s perfect!
Step 7: Bake the Cake
Pour the batter into the prepared pan and bake for 30 minutes or until a toothpick inserted in the center comes out clean.
Step 8: Cool the Cake
Once baked, remove the cake from the oven and let it cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
Step 9: Prepare the Ganache
While the cake cools, beat the softened cream cheese in a bowl until smooth. Gradually add the heavy cream, powdered sugar, and vanilla extract, mixing until fluffy.
Step 10: Fold in Cookies
Gently fold in the crushed cookies into the ganache until evenly distributed.
Step 11: Frost the Cake
Once the cake is completely cool, spread the cookies and cream ganache over the top, allowing it to drip slightly over the edges for an enticing look.

Step 12: Garnish and Serve
Top with additional crushed cookies or chocolate shavings for an extra touch. Slice and serve to your delighted guests!
