This high altitude strawberry matcha cake has three layers of soft matcha cake, frosted with fluffy strawberry buttercream. This cake gets its natural pink and green colors from matcha green tea powder and crushed freeze dried strawberries. A summery strawberry sprinkle mix makes an easy and pretty decoration.
All recipes on Curly Girl Kitchen are developed for high altitude at 5,280 feet. See FAQs for adjusting to higher or lower elevations.
Preheat the oven to 350 F, and position a rack in the center of the oven. Spray three 9-inch round cake pans with non-stick baking spray.
In a large bowl, sift together the flour, sugar, matcha powder, baking powder, and salt.
In a separate bowl, whisk together the melted butter, milk, sour cream, eggs, oil, and vanilla.
Whisk together the wet and dry ingredients until smooth and combined, about 15 seconds. Divide the batter between the prepared cake pans.
Bake the cakes for about 30-32 minutes, until a toothpick or cake tester inserted in the center comes out clean, and the tops spring back when gently touched.
Cool the cakes in the pans for 15 minutes, then gently turn them out onto the cooling rack to cool completely before frosting.
Strawberry Buttercream
In the bowl of your stand mixer fitted with the paddle attachment, beat the softened butter for one minute, until smooth.
With the mixer on low, add the powdered sugar by spoonfuls, the meringue powder, crushed freeze dried strawberries, and salt.
Add the vanilla, and increase the speed to medium. Whip the buttercream for 4-5 minutes, stopping to scrape the bowl down several times, until very light and fluffy. Add the milk only if needed for consistency. Turn the speed down to "stir" and mix for one more minute.
Assembly
If the tops of the cakes are domed, use a sharp, non-serrated knife to slice off a small portion of the domed tops, so the cakes are level for stacking.
Fill and frost the cooled cakes with the strawberry buttercream, then frost the cake all over with a thin crumb coat of buttercream. Refrigerate the cake for 15 minutes, then frost it with a final smooth coat of buttercream.
For a standard sized three layer cake that serves 16 people, use three 9-inch round cake pans. You can also use 8-inch pans for slightly thicker layers, but the cake will need to bake for a few minutes longer.
For a smaller cake that serves 8 people, you can cut the recipe in half, and bake the cake in three 6-inch cake pans, for 25-30 minutes. The photographed cake in today's post is a 6-inch cake.
Store leftover cake in an airtight container at room temperature for up to three days.
For the buttercream, you can easily crush freeze dried strawberries into a powder with a small food processor or Ninja, or simply place them in a freezer bag and crush them manually with a rolling pin.
