Follow these simple steps to create your Butterfinger Bomb Cake:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. Mix Dry Ingredients: In a large bowl, sift together the flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt.
3. Combine Wet Ingredients: In another bowl, whisk together the eggs, milk, vegetable oil, and vanilla extract until well combined.
4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, mixing until fully incorporated.
5. Add Boiling Water: Carefully stir in the boiling water until the batter is smooth and well combined. The batter will be thin.
6. Divide Batter: Pour the batter evenly into the prepared cake pans.
7. Bake: Place in the preheated oven and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
8. Cool the Cakes: Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then, transfer them to wire racks to cool completely.
9. Make Peanut Butter Frosting: In a medium bowl, beat together the creamy peanut butter and powdered sugar until smooth. Gradually add the heavy whipping cream, beating until light and fluffy.
10. Layer the Cake: Once the cakes are completely cooled, place one layer on a serving platter. Spread a generous amount of peanut butter frosting on top.
11. Add Crushed Butterfinger: Sprinkle crushed Butterfinger candy over the frosting layer.
12. Top with Second Layer: Place the second cake layer on top and cover the entire cake with the remaining peanut butter frosting.
13. Final Touch: Garnish the top of the cake with more crushed Butterfinger candy for that extra crunch.
