Preparation Steps

• Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
• In a large bowl, whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt.
• In a separate bowl, whisk together eggs, milk, oil, and vanilla extract.
• Add the wet ingredients to the dry ingredients and mix until just combined. Gradually stir in the boiling water until the batter is smooth.
• In a medium bowl, beat together softened cream cheese and sugar until smooth. Beat in the egg and vanilla extract until well combined.
• Pour half of the chocolate cake batter into the prepared baking pan. Dollop spoonfuls of the cream cheese mixture over the batter. Sprinkle half of the crushed Oreos over the cream cheese.
• Pour the remaining chocolate cake batter over the top. Dollop the remaining cream cheese mixture and sprinkle with the remaining crushed Oreos. Use a knife or skewer to gently swirl the cream cheese and Oreos into the cake batter, creating an 'earthquake' effect.
• Bake for 35-45 minutes, or until a wooden skewer inserted into the center comes out with moist crumbs attached.
• Let the cake cool in the pan for at least 20 minutes before slicing and serving.
