This Glazed Fudge Birthday Cake is a one-layer chocolate cake mixed in a food processor. The chocolate glaze is rich but not too sweet. It is our favorite birthday cake.
What makes a chocolate cake superior?
Your requirements may differ from mine. I like a super moist cake with a fairly tight crumb. The texture should not be too heavy or too airy. Furthermore, the chocolate flavor must be intense.
What about the frosting, or glaze in this case? Not too thick or too sugary and smo-o-o-o-oth on the tongue.
If you agree…BINGO!
But sometimes, it’s about more than the recipe itself.
I made this cake for my husband’s birthday last Sunday. It’s a tradition in our family. It turned out to be a bittersweet celebration because his mother died the day before.
While frantically going through photo albums before my mother-in-law’s funeral, I found the picture below. It was taken at my oldest son’s birthday party. (I counted the candles.)
I’m just telling you this because I’ve been making it for a long time. It is SO DELICIOUS!!!
Tips for success with Glazed Fudge Birthday Cake:
It’s made in a food processor.
I acquired the recipe while assisting with a cooking school taught by Abby Mandel. At the time, she had just published a new cookbook called Cuisinart Classroom.
This is the only cake recipe I have that is made in a food processor. While I’m sure this cake could be made with a regular mixer, I have never tried it myself. The author originally touted the food processor as a way to make a chocolate cake without melting the chocolate, supposedly quicker and more flavorful.
Maybe Ms. Mandel is right. I’m not sure. Nevertheless, the cake tastes fabulous. Can’t argue with fudge-y, moist, and tender.
You must use a 9-inch springform pan.
Anything smaller and you risk an overflow of cake batter in your oven. On the other hand, you could use an 8-inch pan plus a few cupcakes if you like
You don’t have to use a springform pan. However, the cake is much easier to remove when you do. Be sure to line the bottom as outlined in the recipe.

- Add the eggs and cocoa and process 1 minute.
- Add remaining sugar (1 cup) and process 1 minute, stopping once to scrape down the inside of the bowl.

- Put the chocolate and powdered sugar in the work bowl and pulse food processor on and off 3 times to chop the chocolate, then process continuously until it is finely minced.
- Boil water and butter together. With the machine running, pour the hot water and butter through the feed tube and process until the chocolate is melted. Add the flavoring and process for 5 more seconds.
- Refrigerate the glaze until it begins to thicken then spread over the surface and sides of the cake.
To Decorate: Melt 1 1/2 ounce white chocolate in a small zippered plastic bag. Make a tiny snip across one corner of the bag. Draw parallel strips across the cake. Using a thin knife, draw lines perpendicular and parallel across white chocolate lines to make a chevron design.
