Step-by-Step Instructions
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). This ensures your cake bakes evenly and rises beautifully.
Step 2: Prepare the Baking Pan
Grease a 9×13 inch baking pan with butter or cooking spray, and line the bottom with parchment paper for easy removal.

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, mix the eggs, milk, oil, and vanilla extract. Whisk until smooth and combined.
Step 5: Combine Wet and Dry Mixtures
Pour the wet ingredients into the dry ingredients and mix until just combined. Be careful not to overmix; a few lumps are okay!

Slowly stir in the boiling water, mixing until the batter is smooth. This step is crucial as it enhances the chocolate flavor and creates a moist cake.
Step 7: Bake the Cake
Pour the batter into the prepared baking pan and bake for 30 minutes, or until a toothpick inserted in the center comes out clean.
Step 8: Prepare the Crunch Topping
While the cake is baking, melt the butter in a saucepan over low heat. Stir in the chopped hazelnuts and brown sugar until well combined. Remove from heat and mix in the chocolate chips.
Step 9: Add Topping to Cake
Once the cake is baked, remove it from the oven and immediately spread the hazelnut crunch topping evenly over the hot cake. Return to the oven for an additional 10 minutes.
