What makes this the best chocolate cake ever
This gooey chocolate butter cake is based on a classic St. Louis butter cake. It's essentially a soft, buttery cake with a custard gooey filling that bakes right into the cake. Like my gooey lemon butter cake recipe!
Each part only requires one bowl, and you don't need an electric mixer for the cake batter. This makes the cake so easy to make.
Make ahead and storage
For the best gooey texture, I recommend serving the cake slightly warm. You can rewarm the cake for a gooey texture as well!
For a firmer texture, chill the chocolate butter cake for a few hours or overnight (like you would a cheesecake). Sprinkle with cocoa powder and serve.
This chocolate butter cake will keep well in the fridge (store in an airtight container or cake carrier) for up to 3 days. You can freeze slices in an airtight container for up to 2 months. Wrap them in parchment paper to prevent them from sticking in the freezer.

Key ingredients
Full steps and ingredients in recipe card below. But read through these for all the tips you will need for success!
Dark chocolate: Dark chocolate will give the cake the best flavour. If you can't get any, use semisweet chocolate chips instead.
Cocoa powder: Use natural cocoa powder for best results. You can also use dutch processed if that's the only one you have on hand. Natural cocoa powder will only have one ingredient (cocoa powder) in the ingredient list.
Butter: Since this is a butter cake, good quality real butter will give the best results.
Cream cheese: Use brick style full fat cream cheese. Low fat cream cheese won't set in the filling because it's too watery.
All purpose flour: Weigh the flour to get the most accurate results. If you don’t have a scale, measure properly by stirring the bag and spooning gently into a measuring cup. Scrape the excess off the top with the flat edge off a knife without packing it into the cup.
Step by step: cake batter
Step 1 - Preheat oven to 340°F (170°C). Butter the bottom and sides of a 9” springform round baking pan with a cold piece of butter. If using a regular pan, line the bottom and sides with a whole piece of parchment paper so you can lift it out afterwards.
Step 2 - Combine butter and chocolate in a small saucepan or microwaveable bowl. Heat on low heat, stirring constantly until melted. Let cool to room temperature.
Step 3 - In a large bowl, whisk together sugar, salt, egg, and vanilla until thickened. Pour melted butter and chocolate into the same bowl, whisk until combined.
Step 4 - Sift flour, cocoa powder, and baking powder right into the same bowl. Fold to form a thick batter.
Step 5 - Transfer the batter into the prepared baking pan and spread it out evenly.
How to make the filling
Step 1 - In a large bowl or stand mixer, combine cream cheese, powdered sugar, egg, vanilla, salt, and cocoa powder.
Step 2 - Beat until fully smooth and creamy (use an electric mixer or immersion blender for best results). Pour the filling on top of the cake batter.
Step 3 - Place the baking pan on a larger baking sheet to catch any butter drips in case the baking pan leaks. Bake for 45-55 minutes, or until the edges are set and the middle of the cake is slightly puffed. The middle will still be jiggly! If you see it browning too quickly, tent the top with a piece of aluminum foil.
Step 4 - Let cool for 10 minutes before releasing the sides of the pan or lifting out the cake. Slide it onto a serving plate and sprinkle with cocoa powder. Serve at room temperature for extra gooey-ness or chill for a firmer texture.
FAQ
I haven't tested any in this cake so I can't say.
Microwave: Heat pieces of or the whole cake in the microwave for about 20 seconds, checking every 5 seconds.
Oven: Pop it into a cold oven and heat to 250°F (120°C). Leave it in for about 10 minutes or until warm.
The edges will be set and the middle will still be jiggly and slightly puffed. This will ensure the cake sets properly after cooling.
I recommend baking it into an 8" or 9" square baking pan and cutting into individual bars after the cake fully cools and sets.

I have this cake currently in the oven, and we can’t wait to try! I just want to say I love the way you write out your recipes with the ingredients listed below the steps. As an avid baker, you have no idea how much I appreciate this! Makes it so easy! ♥️

I made this cake this past weekend for my family but my cousin is allergic to gluten so I used cup for cup flour instead and it was amazing. One thing I would say is that it’s definitely best to eat it the day of when using a gluten-free flour but the flavor was exactly how I expected it and so much more. I had also made the lemon cake like this but with regular flour and when comparing the two you really couldn’t tell the difference as far as texture with the cake part so if you have a gluten allergy you can definitely make this and still enjoy it.

So happy you loved it, thank you so much!
