Instructions
Make the Cakes
Preheat the oven to 350°F. Grease two 8-inch round cake pans.
In a small bowl, mix the milk and lemon juice. Set aside for 10 minutes to curdle.
Pulverize the freeze dried strawberries in a food processor, blender, or by smashing them with something heavy in a sealed bag until it forms fine crumbs.
In a large mixing bowl, whisk together the cake flour, baking powder, baking soda, salt, and freeze dried strawberry powder. Set aside.
In a small mixing bowl, whisk together the milk + lemon juice, vanilla extract, and Greek yogurt. Set aside.
In a stand mixer or in a large mixing bowl with an electric hand mixer, beat the softened butter and granulated sugar for about 3 minutes, until it is smooth.
Add the eggs and mix until it’s combined.
Add about one-third of the dry flour mixture to the butter and sugar. Gently mix with a large spatula until there's no dry flour visible. Add one-half of the wet milk mixture. Gently mix again until it's fully combined. Continue alternating between adding the dry and wet ingredients, ending with the dry ingredients. Give the bowl a final scrape and mix, to ensure everything is evenly combined.
Divide the batter equally between the two greased cake pans and smooth the top of the batter with a spatula. Bake for 30 to 40 minutes, until a toothpick comes out clean from the center of each cake. (Be sure to check each cake for doneness, as they could finish baking at different times.)
Transfer the cakes to a cooling rack to cool completely before assembling your layer cake with the filling.
Make the Buttercream
Pulverize the freeze dried strawberries into fine crumbs. Set aside.
In a stand mixer or in a large mixing bowl with an electric hand mixer, beat the softened butter for about 5 minutes, until it is soft and fluffy.
Add one cup of powdered sugar and beat it on a low speed until the sugar is incorporated. Repeat with the remaining powdered sugar and mix until it’s smooth, fluffy, and pale.
Add the vanilla extract, salt, and pulverized freeze dried strawberries. Mix again on high speed, scraping the sides of the bowl as needed, until it's well-combined and smooth. Set aside.
Assemble the Layer Cake
Use a serrated knife to trim the tops off the cakes so they are level. (You can trim off the sides as well, but I prefer to leave them on - it looks cleaner since we aren’t frosting the sides.)
Spread one tablespoon of the buttercream frosting on a cake plate, then place the first cake layer in the center of the cake plate.
Fill a piping bag with a large open round nozzle with the strawberry buttercream (or you can fill a gallon-sized Ziplock bag and cut the corner off). Pipe a thick outer ring of buttercream on the top of the cake, followed by another thick inner ring (see the photo in the blog post above for reference).
Fill in the two spaces between the rings of frosting with the strawberry jam.
Place the second cake layer directly on top upside-down (so the flat bottom is on top). With the remaining buttercream, pipe it on the sides to fill in any gaps and pipe it on the top of the cake, using an offset spatula to spread it in an even layer.If the frosting feels really soft, let your layer cake sit in the fridge for 20 minutes so the frosting can firm up a bit. Decorate with fresh strawberries, and enjoy!!
Notes
Buttercream: If you feel like your buttercream is too stiff, mix in one tablespoon of milk at a time to loosen your buttercream.
Room Temp Ingredients: Have all your ingredients (especially the butter, milk, eggs, and yogurt) at room temperature to help everything combine easily.
Don't Overmix: Be careful not to overmix your cake batter, which can cause it to look like it has big holes in it. Mix slowly and gently with a spatula as you're adding the dry and wet ingredients.
Make Ahead: If you are decorating your cake with fresh strawberries, wait to add them just before you serve your cake. Otherwise they could seep moisture onto your cake or dry out in the fridge.
Storing: Store your cake wrapped tightly in plastic wrap in the fridge.
