Chocolate Cake with a Coffee Swiss Meringue Buttercream and Maple Glazed Walnuts

On one of my recent blog posts, Orange Cardamom Cake with Blackberry Curd, a reader left a comment that left me scratching my head. She wrote, “I have tried to make this cake twice and the cake has fallen – severely – before taking it out of the oven. I have years of baking experience, and can’t get this to bake right.”

Of course, my heart sank. How could this be? I referred back to the cake recipe and scrutinized it line by line, and was still left baffled. I knew I had baked this cake several times and wondered what had gone amiss. After several conversations between the reader and myself, and I discovered exactly what went wrong. She had used a 6 inch pan the first time and an 8 inch pan the second time, when the recipe had called for a 9 inch pan. Using pans of another size, other than what the recipe calls for, (even a mere inch) can cause the cake to collapse in the middle and/or cause the excess to flow over the edge of the pan.

The fact that this particular reader was a seasoned baker, made me realize that although many home bakers out there may have decades of experience, it is probably in baking the same repertoire of recipes over and over. For instance, a simple pound cake or chocolate cake most likely won’t sink if substituting with a slightly different pan size. But for a genoise, sponge, angel, chiffon or any cake using egg whites and air to leaven (raise/suspend), the cake would definitely end up with a monumental crater.

I’ve decided to do a quick checklist here with brief explanations on how to achieve that perfect cake. I’ll dedicate a more detailed blog post at a later time but for now I thought I’d share these quick tips to help you avoid any cake disasters.

-Check that your oven’s temperature is correct with an oven-safe thermometer.

-Always use the pan size indicated in the recipe. Using a smaller pan than what is called for in the recipe will cause the cake to collapse in the middle (and over flow on the sides). While baking, the cake expands and rises and has nowhere else to go. Thus, the flop and spillover. On the opposite spectrum, using a pan larger than what the recipe indicates may result in a flat and dry cake.

-Grease pan with butter and dust with flour on sides and line bottom of pan with parchment paper (that you’ve traced and cut out).

-Glass and dark-coloured pans usually bake things faster…reduce oven by about 25F or check up on cake a bit earlier. Normally recipes are based on aluminum/light-coloured pans.

-Always measure flour and most ingredients by weight. If you don’t have a scale, don’t scoop the flour directly with a measuring cup. Take a spoon and spoon it into the measuring cup and level off with a knife.

-Sift all your ingredients including sugar (especially brown sugar). Nothing like baking a gorgeous cake only to find a big air pocket inside after slicing into it. 

-Make sure you thoroughly whisk your flour and baking powders/sodas together

-Have all your ingredients come to room temperature (unless otherwise stated) – especially eggs, milk, creams, cheeses etc. This helps create a lighter texture and an even bake.

-If you’ve forgotten to bring your eggs to room temperature, soak them in a bowl of warm water for 10-15 minutes. 

-Don’t stray too much from the recipe. If it says 2 cups of flour, don’t add another half cup. In baking, even the slightest variation in ingredient ratios can throw the entire recipe off.

-When testing with a toothpick, dont wait till it comes out perfectly clean. A few crumbs on the toothpick is the perfect time to take out of the oven as the cake will continue to cook when taken out

-Brush your cakes with a simple sugar syrup while still warm. Its simple to make- equal amounts of water to sugar…bring to boil and brush over cakes. This will make your cakes moist for days!

Now back to what this blog post was really about…chocolate cake. The recipe below was tested at least a dozen times with various ingredients…sour cream instead of yogurt, butter instead of oil, unsweetened chocolate rather than semi sweet, raspberry buttercream instead of coffee…etc. And the end result was a gorgeous, moist, crumb. Sweet but not overly sweet with a smooth silky coffee buttercream with a nutty crunch. The recipe below is for a double layer cake and is quite large. You can easily make this cake into a single layer by dividing all the ingredients by half. This makes a single nine inch cake. I hope you enjoy it. 

Bon app!
