Ingredients You’ll Need
- Dark chocolate – For a rich and satisfying brownie, go for dark chocolate with a cocoa percentage of 65% to 75%.
- Unsalted butter
- Brown sugar – Brown sugar is preferred in brownies because its higher molasses content adds a rich caramel flavor, making it richer and more indulgent.
- Eggs – use room temperature eggs because they mix more easily and evenly into batters, improving the texture and structure of the cake.
- All-purpose flour
- Sugar
- Baking powder – make sure your baking powder is not expired. Fresh baking powder is essential to ensure proper leavening.
- Milk – Adds moisture to the butter cake, making it soft and tender. You can also use plain yogurt or sour cream for similar result.

How To Make Brownie Butter Cake
Step 1: Grease and line a 10cm x 20cm (4×8-inch) loaf pan with aluminum foil. Preheat the oven to 180°C (350°F).
Step 2: To make the brownie, melt the chocolate and butter over low heat. Remove from heat and let it cool slightly. Stir in the brown sugar until well blended.
Step 3: Add the egg and mix well. Fold in the flour and combine until smooth. Pour the batter into the prepared pan and bake in the preheated oven for 15 minutes. Remove from the oven.
Step 4: To make the butter cake, beat the butter with sugar until creamy. Add in the eggs, one at a time, beating well after each addition.
Step 5: Fold in the sifted flour and baking powder, alternating with the fresh milk, and mix until the batter is smooth and well combined.
Step 6: Spread the butter cake batter over the brownie layer. Bake in the oven at 160°C (320°F) for 25-30 minutes or until fully cooked. Insert a cake tester into the center to check for doneness.
Pro Tips For The Perfect Brownie Butter Cake
- To save time, mix the butter cake batter while the brownie layer is baking. That way, I’m ready to pour it right onto the hot brownie as soon as it’s done.
- Once the brownie layer is baked, I pour the butter cake batter quickly onto the hot brownie. The batter melts instantly and spreads evenly over the top.
- You can also put the butter cake batter into a piping bag with a large hole at the tip. This makes it easy to quickly pipe the batter onto the brownie layer without making a mess.
- Gently tap and shake the pan to smooth out the top. This gives it a nice, even finish once it’s baked.

You need eggs.
I plan to try this but will add glacé orange to the brownie batter and orange zest to the butter cake batter.

I made this yesterday and it came out perfect. Super easy to make. I added some vanilla and salt to both batters and I only had a 9×5 pan, so mine came out a little shorter & wider, but it was delicious. Like others, I did have to let mine bake quite a bit longer, but I just covered the top with foil to prevent browning & I had no problems. Thanks!
Hi, i made it yesterday, turn out superb yummy. My family love it and my morocco hubby love it and the cake only last 30 min on the table. LOL. 1st time baking brownie and yess it was a succesful one. Although my butter cake did not look as smooth as yours (i add in orange zest) but me and the whole family enjoy it. Thanks ?
I just served this to my family and it tasted SO delicious!!! The only thing was, mine was more dense and not “Starbucks’s moist” like your posted picture and so I was wondering if I either over stirred or under stirred the cake batter (the brownie layer was perfect!
Hi,
Just to check, how long will the cake last? Thanks!
A few days.
I tried this cake.Was yummm.Brownie part was very tasty.The texture of the cake was awesome.
Please advise the chocolate used is chocolate couverture or compound. Will these 2 types of chocolate give different brownie texture?
