Blueberry Passion Fruit Cake

Makes 3 Layer 6-inch Cake


1/2 cup (113 grams) organic salted butter, softened

212 grams (3/4 cup plus 3 tablespoons) organic cane sugar

1 teaspoon organic vanilla extract

102 grams (about 3 large) organic egg whites

1/2 cup (113 grams) organic sour cream

1/4 cup organic milk

170 grams (1 cup plus 3 tablespoons) all natural cake flour

1 teaspoon baking powder

1/2 teaspoon fine sea salt


142 grams (scant 1 cup) organic blueberries (you can use fresh or frozen)

70 grams (1/4 cup plus 1 tablespoon) organic cane sugar

1/4 cup water


1 1/4 cups (283 grams) organic salted butter, softened

567 grams (4 cups) organic powdered sugar, sifted

1/4 teaspoon organic passion fruit flavor

1 tablespoon organic milk

Color Kitchen Foods Pink, Blue and Yellow Dyes (find here)


85 grams (3/4 cup) organic walnuts, chopped

Method To make the filling: In a medium pot add the blueberries, sugar and water. Cook over medium heat until the mixture has reduced by half and you have a thick compote. You can do this the day before and store in the fridge overnight. Just make sure this mixture is cooled completely before assembling the cake.

Preheat the oven to 350°F. Line three 6-inch cake pans with parchment paper.

To make the batter: In the bowl of a stand mixer fitted with the whisk attachment, add the egg whites. Whisk until stiff peaks form. Remove and put in a separate bowl.

Using the same mixing bowl (no need to wash), with the paddle attachment add the butter, sugar and vanilla extract. Mix on low until all ingredients are combined.

In a separate bowl, add the gluten free flour, salt and baking powder and whisk together.

Add the sour cream, milk and flour mixture to the mixing bowl and mix on low until combined.

Add the egg whites to the butter mixture and fold in. Keep stirring until you have a smooth cake batter.

Pour batter evenly into each pan, about 255 grams each. Bake for 20 minutes or until a wooden pick inserted in center comes out clean. Allow to cool completely in the cake pans.

To make the frosting: In the bowl a stand mixer fitted with the paddle attachment, add the butter, powdered sugar, milk and passion fruit flavor. Mix on low until all ingredients are combined, then speed mixer up to high for 1 minute or until light and fluffy.

On a cake stand or cake spinner, place the first cake layer and spread a very small amount of frosting onto the cake, you want this to be very thin.

Put some frosting in a piping bag with Ateco tip #804 (or no tip at all). Pipe a boarder around the edge of the cake, this will hold in the blueberry filling. Put half of the blueberry filling into the middle and spread out evenly.

Top with the second cake layer and repeat this process. Crumb coat (find tutorial here) the outside of your cake to seal in all crumbs and filling. Frost the outside of your cake smooth.

Add the chopped walnuts to the boarder around the bottom half of the cake.

With the remaining frosting, separate it into five small dishes. Color each dish blue, yellow, red, purple and green. For red use pink and yellow (a little more yellow than pink), for purple use equal parts blue and pink and for green equal parts yellow and blue. The more color you put in the darker the colors will be, I used a lot to get these bright colors. When adding colors into each dish, add a splash of water, this will help make the colors combine better and also be more vibrant.

Once the colors are made, put each into a piping bag with a decorating tip. You can use ay tips you want. But, I used used Ateco tip #30 for blue, for purple I used tip #164, for yellow I used tip #26, for red I used tip #32 and for green I used tip #21.

Pipe any design you like on the cake, just wing it and have fun!

Store in the fridge for up to 3 days.

Gluten Free - Replace the all natural cake flour with 170 grams (1 cup plus 1 tablespoon plus 1 teaspoon) organic gluten free flour blend.

High Altitude - Bake at 350°F for 17 minutes or until a wooden pick inserted in center comes out clean.
