directions
-
Preheat and prepare pan. I preheat the oven to 350 °F and grease—or line—a 9×13″ or 9″ round/bundt pan
-
Combine wet ingredients. I melt the butter, stir in sugars, mix in eggs one at a time, and add vanilla.
-
Mix dry ingredients. In another bowl, I whisk together flour, cocoa powder, baking powder, and salt.
-
Make the batter. I fold the dry mix into the wet ingredients until just combined. If I’m using box mixes, I combine chocolate cake mix and brownie mix with eggs, oil, water, and toss in chocolate chips
-
Bake. Pour the batter into the pan and bake for 30–50 minutes (time varies by pan size) until a toothpick comes out with moist crumbs .
-
Cool then glaze. Let the cake cool. I heat cream until it simmers and pour it over chopped chocolate to make a silky ganache, then drizzle it over the cake
-
Serve. Optionally, I dust with powdered sugar or garnish with berries or ice cream.

FAQs
Can I use boxed mixes instead of scratch ingredients?
Yes—many of us combine boxed chocolate cake and brownie mixes with eggs, oil, and water for an effortless and decadent bake
How do I know when it’s done?
When a toothpick comes out with a few moist crumbs (not wet batter), it’s perfectly fudgy—avoiding overbaking keeps it tender
Can I make this gluten‑free?
Sure—swap in gluten‑free flour for the scratch version, or use gluten‑free boxed mixes if available.
What’s the best ganache ratio?
I use equal parts chopped chocolate and hot cream. Let the cream sit for a few minutes, then whisk until glossy and smooth for the perfect pourable consistency
Can I add fruit or nuts?
Absolutely—I’ve folded in nuts, berry compote, or tossed fresh raspberries and whipped cream on top. It adds texture and freshness.
Conclusion
I absolutely love this Chocolate Brownie Cake for being the ultimate chocolate indulgence—rich, fudgy, and vibrant. Easy to bake, impressive to share, and endlessly adaptable, it’s become my go‑to treat for dessert cravings, celebrations, or a simple cup of coffee on a quiet afternoon. Enjoy every slice!

Ingredients
Cake Layer:
1 box (15.25 oz) chocolate cake mix

1¼ cups water, room temperature
1 cup vegetable oil

1 cup heavy whipping cream

Instructions
Preheat oven to 350 °F (177 °C). Grease a 10″ bundt pan with nonstick spray.
