Welcoming in September with cake! As some of you know, Asher’s birthday was this week. And every year I always share a new dessert with her birthday in mind.
This year it’s a classic chocolate cake, but updated in surprisingly delicious ways!
I’ve been excited to share this cake all week. It’s such a special recipe that I know will become a go-to whenever I need a birthday cake!! We all love this.
The thing you should know about Asher is that while she has a sweet tooth, she’ll only indulge in chocolate. She’s not a fruit dessert girl, she’s just like my mom.
So of course, her birthday cake needed to be chocolate!!
Here are the details
I wanted this cake to feel very classic and just like the chocolate cake we grew up eating, but with more flavor and richness.
I knew a good olive oil would be perfect for adding a sweetness and fruitiness that sets this cake apart. You don’t know it’s there while eating bite after bite, but it makes the chocolate stand out.
Start with the cake. Mix the oil with the wet ingredients. Add maple to sweeten the cake. Then, mix in the dry ingredients. It’s a very basic process.
Bake the cake in a rectangular baker for simplicity and ease.
For the frosting. I made a rich fudge-like chocolate frosting, it’s old-school delicious. Chocolate melted together with cream and honey for smoothness. There’s plenty of pure vanilla mixed in. And then a key ingredient is stirred in at the end – sour cream.
Now, this certainly IS just like the old-school frosting everyone LOVES. Very creamy, rich, and fudgy. And I love that it’s not too sweet, but just sweet enough.
To finish, I topped my cake with chocolate curls and sea salt for a salty-sweet finish. And that’s it. Each bite is filled with sweet moist cake and fudgy chocolate frosting.
Best kind of any-day cake to bake, no reason required – though it is fun for a fall birthday. I was so excited when Asher LOVED every last bite of this cake. My parents and Asher even flew with the cake to California to celebrate with my brothers!
