Coffee Buttercream Sans Rival
serves around 8
Meringue
This recipe is good enough to make three rectangular sheets that could fit in a half-sheet tray (18 by 13 inches). I decided to pipe the meringue into rounds instead of rectangles, but I still used a sheet tray lined with a silicone mat that measures 11 5/8 by 16 ½ inches. Two rounds fit in the silicone mat so I worked in batches. Alternatively, you can also use cake pans, greased, lined with parchment, greased again, and floured.
- 180 grams clean egg whites
- a pinch of cream of tartar
- 170 grams granulated sugar
- 10 grams all-purpose flour
- 50 grams granulated sugar (for the flour and nut mixture)
- 60 grams cashew nuts, processed/chopped into very small pieces
- additional cashew nuts for decoration
Coffee Buttercream
recipe adapted from Memories of Philippine Kitchens by Amy Besa and Romy Dorotan
- 7 egg yolks
- ¾ cup sugar
- ½ cup heavy cream
- 454 grams/1 pound unsalted butter at room temperature
- 2 teaspoons vanilla extract
- 6 tablespoons coffee powder (or more if a stronger flavor is desired)
Beat the yolks and sugar using an electric mixer fitted with a whisk attachment, until it becomes light and lemon-colored. Warm the heavy cream in a large saucepan, until bubbles appear around the sides. Whisk the heavy cream into the yolks and return it to the saucepan. Stir over low heat until thick, around 10 – 12 minutes. Be careful not to let it boil or else it will curdle. Remove from heat, transfer to a large bowl (or the bowl of an electric mixer) and let it cool.
You can whisk the buttercream by hand or use an electric mixer, with the paddle attachment. Either way, add the butter into the cooled custard bit by bit, beating the pieces in until completely absorbed before adding in the next. Add the vanilla extract. When all the butter has been incorporated and the mixture is smooth, you can set aside 1/3 of the buttercream, and mix in the coffee powder into the remaining 2/3. Set aside until ready to use.
Assemble: place one layer of meringue on a plate or cake board. Using a straight or offset spatula, spread an even but thin layer of buttercream on it, and top with the second layer. Repeat, then top with the third layer. Spread the buttercream on top, and along the sides. When the coating is generous and even, you can pipe decorative rosettes using the regular buttercream on top. If the surrounding temperature is a bit warm the buttercream might soften too much for you to achieve good, sturdy piping. At this point you can let the mixture rest in the fridge, or to speed up the process, place it in the freezer for a couple of minutes.
Coat the sides and sprinkle the top with the chopped cashew nuts. When coating the sides, get a handful of the chopped nuts and lightly pat the side making sure that the nuts stick to the buttercream. The excess will fall of and you can clean it up when you’re done decorating.
Place it in the refrigerator or freezer until ready to serve.
