directions

Step 1: Prepare the Cake Batter
Preheat the oven to 350°F (175°C). Grease and flour two 8-inch round cake pans or line them with parchment paper.
In a medium bowl, whisk together flour, cornstarch, baking powder, baking soda, and salt. Set aside.
In a large bowl, beat the softened butter and granulated sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
Mix in the dragon fruit puree and sour cream (or yogurt) until well blended.
Gradually add the dry ingredients to the wet ingredients, alternating with the milk. Mix until just combined.
Gently fold in the fresh blueberries.
Divide the batter evenly between the prepared pans and smooth the tops.
Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
Let the cakes cool in the pans for 10 minutes, then transfer to wire racks to cool completely.

Step 2: Make the Dragon Fruit Frosting
In a bowl, beat the softened butter until creamy.
Add the dragon fruit puree and vanilla extract, mixing until smooth.
Gradually add the powdered sugar and beat until fluffy.
Add heavy cream, one tablespoon at a time, until the desired frosting consistency is achieved.

Step 3: Assemble the Cake
Once the cakes are completely cool, spread a layer of frosting on top of one cake layer.
Place the second cake layer on top and frost the top and sides of the cake as desired.
Decorate with extra blueberries or dragon fruit slices if desired.
