I made this cake a couple of times previously, and twice over the weekend - one with strawberry SMBC and today, with chocolate SMBC. I did not get to taste the strawberry version but the chocolate was seriously delicious. I love that the dark chocolate in the frosting came out so rich and it did not taste buttery at all.
This is a super easy one bowl chocolate cake that is nearly impossible to screw up, unless you add too much salt like I once did. If you're not as forgetful as me you'll be fine. There's no risk of over-beating, under-mixing, etc. Swiss Meringue Buttercream used to be a complete mystery to me, but it is really easy to make and holds up great once you learn how to. Sweetapolita has a wonderful
guide with step-by-step pitcures, be sure to check it out if you're new to making SMBC!
My SMBC usually whips up pretty well despite this hot and humid weather, but with the addition of the chocolate today, it was unusually soft. In my haste to complete the cake, I must have added the still-warm chocolate into the SMBC. So, please do not make the same mistake as me. If you did, however, do that, don't worry, it's not the end. Simply chuck the entire bowl into the refrigerator for about 20-30 minutes, and mix it again using your paddle attachment (or hand mixer) till it comes back to its satiny texture.
