Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease and flour a bundt pan to prevent sticking.
Mix Dry Ingredients: In a bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
Cream Butter and Sugar: In a separate large mixing bowl, cream together the softened butter and sugar until fluffy. This should take about 3-5 minutes.
Add Eggs and Vanilla: Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
Combine Mixtures: Gradually add the dry ingredients to the butter mixture, alternating with buttermilk, mixing just until combined.
Add Boiling Water: Carefully stir in the boiling water (the batter will be thin). Then, fold in the chocolate chips.
Pour into the Pan: Pour the batter into the prepared bundt pan, smoothing the top.
Bake: Bake for 50-60 minutes or until a toothpick inserted in the center comes out clean. Let the cake cool in the pan for about 10 minutes before transferring to a wire rack.
Serve and Enjoy: Once cooled, dust with powdered sugar or drizzle with chocolate glaze, and enjoy!
