Fluffy and tender, this chocolate cake comes together quickly in one bowl. It’s a friendly little birthday cake with its dead simple frosting (or a really great snack without). A blend of oil and buttermilk or yogurt keeps the crumb moist, as does a nice pour of hot tea. Oolong gives the cake a floral aroma, while using coffee instead highlights the cocoa’s bittersweetness. Plain hot water gives this an old-fashioned chocolate cake flavor. The two-ingredient frosting – essentially cream and chocolate melted together, then cooled until thick enough to swoop and swirl – can be made in the same bowl used for the cake batter. You can sprinkle flaky salt, chopped toasted nuts or sprinkles on top too. But, frosted or not, this cake welcomes coffee, tea or ice cream.

Preparation

  1. Step 1

    Make the cake: Heat oven to 350 degrees. Rub oil all over an 8-inch square cake pan.

  2. Step 2

    Whisk the flour, sugar, cocoa powder, baking powder, baking soda and salt in a large bowl. Add the eggs, buttermilk, oil and vanilla, and stir with the whisk until smooth. It will be thick at this point; gently smack the whisk against the bowl to release any batter stuck inside.

  3. Step 3

    Add the hot tea and whisk until very smooth. Switch to a flexible spatula and scrape all of the batter into the pan.

  4. Step 4

    Bake until a toothpick inserted in the center comes out with a few tiny crumbs, about 45 minutes. Cool completely in the pan on a rack.

  5. Step 5

    If you’re making the frosting, start it as soon as the cake comes out of the oven: Use the same bowl you used for the batter, washing it if you want. Combine the chocolate and cream in the bowl and microwave for 30 seconds. Stir well, then microwave for 15 seconds and stir until smooth. If some chocolate remains solid, zap for 10 more seconds and stir.

  6. Step 6

    If you don’t have a microwave or microwave-safe bowl, set the bowl over a saucepan of barely simmering water and stir until smooth.

  7. Step 7

    Let the chocolate cream cool, stirring now and then, until thickened to the consistency of soft frosting. (This may take up to an hour.) Plop it all over the cake, even if it’s still a touch warm, and use a flexible spatula or a large spoon to swoop and swirl it to cover the top. Cut into pieces and serve.

This can take a reduction in sugar if desired, by a quarter cup or a bit more.

Teach good food safety practices as you teach baking - a bowl that held raw eggs and flour must be washed before mixing something (like icing) that won’t be cooked. Also, it’s far easier to make ganache in a food processor: pulverize the chocolate, heat up the cream to almost scalding, and slowly pour the cream into the machine with the motor running. Add a tablespoon of the liquid if your choice or done vanilla for added flavor.

This is a smaller sized version of Ina Garten’s recipe for Beatty’s Chocolate Cake: always a hit, keeps very well, can be made with gluten free flour. YUM! I use a few tablespoons of golden syrup or corn syrup in the frosting; keeps it glossy and shiny.

Amanda

Wonderful, easy cake for when the chocolate dessert craving kicks in! I didn't have heavy cream, so I made the ganache with remaining buttermilk. It turned out great, super tangy! I was full-fat buttermilk, and I added a pat of butter just to get a little more milk fat in there. I would do it again, but probably with milk chocolate inatead of semisweet to have a better balance with the buttermilk tang.

I made this delicious cake yesterday and we loved it! So easy! But the cake rose up high in the middle and I’m not sure why. I used a 8x8 square cake pan. I used a European convection oven (we have new, powerful ovens) for 40 minutes versus the recommended 45 minutes at 350 degrees. Any thoughts why the cake rose up high in the middle? Still a great cake and I will be making it again.

When I made this, I only had whole wheat flour on hand- ww pastry flour- and was pleased to find it came out fine. I even (as per my usual altering) cut the sugar to 3/4 cup. It passed muster with the grandkids and seemed plenty sweet. And it was easy. Yay!
