How to Make A Buttercream Brushstroke Cake

Hi everyone! I’m back with a new tutorial on a buttercream brushstroke cake. This cake technique is super easy and forgiving to do! It goes with any cake theme such as rainbow, unicorn, buttercream painting, etc. I settled on the rainbow theme for this cake because everyone needs more rainbow cakes in their lives! In addition, I’ve included a short time-lapse video below on how to do the brushstrokes. Let’s get started!
Buttercream Brushstroke Tutorial

Materials needed to create a buttercream brushstroke cake
- Cake Layers
- Buttercream (I used Swiss Meringue Buttercream)
- A good Pastry Brush (Size is up to you! I used one inch)
- Food Colorings (Either gel or powdered colors. I used The Sugar Art powdered colorants Master Elites in Violet, Turquoise Waters, Red Rose, Orange, and Sunshine)
- 1M piping tip
- Sprinkles (Rainbow Sprinkle Jimmies Use CAKEINSPO15 for a 15% discount!)

Instructions
- I baked my favorite vanilla recipe in these Fat Daddio’s 6″ inch cake pans using bake strips to ensure flat cake layers.
- Level the cake layers with Wilton Cake Leveler.
- Frost the cake with buttercream.
- Smooth the cake with the Wilton Cake Scraper.
- Split up buttercream in several bowls with your desired colors.
- I used this process to make the colors with swiss meringue buttercream and the Sugar Art Master Elite colors since the coloring part is a little bit different from your traditional gel colors. However, the gel colors absolutely can be used!
- Lightly dip the pastry brush in one of the colors. For this process, I only used one pastry brush, but you can use more than one pastry brush.
- Apply the brush to the bottom of the cake in an upward stroke.
- Clean the brush with a paper towel to scrape off the remaining color. (Skip this part if you have the same amount of pastry brushes as your colors)
- Repeat the process with the other colors.
- When you are done with the bottom of the cake, repeat the process on the top.
- Pipe the buttercream swirls on the top of the cake with a 1M piping tip.
- Apply the sprinkles after piping the buttercream swirls.
- Enjoy your beautiful cake!
