Two cake posts in a row?!
Not to worry, I have some savory foods in the pipeline coming soon. And then I have more cake. I like to think that this cake is part savory part sweet because it’s a cake that looks like a hamburger!
Do you follow Lyndsay from Coco Cake Land?! She’s one my favorites on the innanet. She’s so funny and sweet and strong and rad. Her new book Coco Cake Land: Cute and Pretty Cakes to Bake and Decorate is out and it is hoooooot!
It’s full of pretty and cute cakes that you can bake and decorate. There are step-by-step photos and things like cactus cakes, rainbow cakes, pineapple cakes with faces and so much more. I like to think that it would make a really cute gift…but we’re not in holiday season just yet (thanks the heavens!) because I’m not about that right now—too stressful.
People keep talking about summer coming to an end but it is still ridiculously hot in Los Angeles. And there are still summer fruits at the market thriving so we’re still in summer and I’m ok with that.
And what is more summer than a hamburger cake? It is super cute and surprisingly easy to put together. No crazy piping skills needed. I will say that it’s component heavy and a bit laborious so I wouldn’t judge you if you went the cake mix route for this one since it’s such a project.
You can also make the cake layers a few days before or even a week ahead. I’m thinking of doing a post on how to make a cake ahead of time because you all ask about this so much and I totally get it! Its way easier to make the cake layers the week ahead and then frost it the day you need it. Doing it all in one day is too much! So that post is coming soon.
In the meantime, enjoy this lil’ hamburger cake.

To Make the Vanilla Cake:
- Preheat the oven to 350 degrees F. Grease and line two 8 x 2-inch round cake pans.
- In the bowl of a stand up mixer fitted with the paddle attachment, beat the butter and sugar on high speed until light and fluffy, about 2 minutes, scraping down the sides of the bowl with a spatula as needed. Turn the mixer down to low speed and add the eggs one at a time until incorporated, then add the vanilla extract.
- In a large bowl, whisk together the flour, baking powder and salt. In a large liquid measuring cup, whisk together the cream and milk.
- With the mixer on low speed, add one-third of the flour mixture, then half of the milk mixture. Keep alternating as you add the mixtures, finishing with the dry ingredients. I mix for about 30 to 60 seconds total—you do not want to overmix this batter, but be sure the ingredients are incorporated.
- Divide the batter evenly among two cake pans and smooth the tops with an offset spatula. Bake for 30 to 35 minutes, checking for doneness at 25 minutes. The cakes will be done when a toothpick inserted in the centers comes out clean and the tops of the cakes are light golden brown.
- Cool the cakes completely in their pans before frosting. Or alternatively, cool them for 30 minutes in their pans and then gently turn them out onto a wire rack to finish cooling completely.
To Make the Chocolate Cake Layer:
- Make sure the oven is preheated to 350 degrees F. Grease and line one (8-inch x 2-inch) round cake pan.
- In a liquid measuring cup, mix together the whole milk and the white vinegar. Let the mixture sit until curdled, about 10 minutes.
- In the meantime, in the bowl of a stand mixer fitted with the paddle attachment, mix together on low speed the flour, sugar, cocoa powder, baking soda, baking powder, and salt.
- Once the milk is curdled, whisk it in a large bowl with the vegetable oil, eggs, and vanilla extract until combined.
- With the mixer on low speed, slowly pour the wet mixture into the dry mixture. Add the hot coffee and mix just until the batter is incorporated, about 30 seconds.
- Add the cake batter to the prepared cake pans and smooth the top with an offset spatula. Bake for 30 to 35 minutes, checking for doneness at 30 minutes.
- Cool the cake completely in its pans before frosting.
To Decorate the Cake:
- In the bowl of a stand up mixer with the paddle attachment, beat the butter on high speed until it is light and fluffy, about 2 minutes. Scrape down the sides of the bowl with a spatula. Add the sifted powdered sugar, vanilla extract and milk, if using. Mix on low speed to combine the ingredients. Once the sugar is incorporated, crank the mixer to thigh speed and beat the mixture for another 2 minutes, until it has more than doubled in volume, for a fluffy whipped frosting.
- Divide the buttercream in half. Set aside one bowl. Divide the contents of the second bowl evenly among three bowls. Mix the green gel color into the first bowl, yellow into the second bowl, and red into the third bowl. Note: sometimes “red” is a difficult color to achieve—it requires a lot of food gel coloring.
- Fill a piping bag fitted with an open star tip with the uncolored buttercream. Fill a piping bag fitted with a leaf tip with the green buttercream. Fill a piping bag fitted with a medium-size round tip with the yellow buttercream. Finally, fill a piping bag fitted with a large round tip with the red buttercream.
- Place a covered cake board on a cake turntable. Pipe a dab of uncolored buttercream onto the cake board. Place the first vanilla cake layer onto the board. Starting from the outside and working your way in toward the middle, pipe the uncolored buttercream in concentric circles, creating a giant, generous swirl of buttercream. Stop when you get to the center.
- My frosting was super soft because it’s summer! So transfer the cake to the fridge to firm up a bit, if needed. Pipe the nest layer of uncolored buttercream just as you did the first layer.
- Next, begin piping green buttercream “lettuce” right on top of the uncolored buttercream layer, using the piping bag with the leaf tip. The idea is not to be too uniform with your leaves! Squeeze the piping bag a little harder to get bigger leaves, and overlap and layer them in a way that looks organic.
- Squiggle on your “mustard” using the yellow buttercream. I pipe large loops all along the exterior, on top of the lettuce layer but not covering it.
- Using the red buttercream for your ketchup, piping this is an ongoing loop on top of the yellow buttercream layer but in between the yellow loops.
- Carefully place the final vanilla cake layer, unleveled and dome side up, on top of the “ketchup buttercream. Gently press down to adhere.
- Place the sugar pearls on top of the cake for a sesame seed bun effect.
