A festive and fun vanilla sponge cake with a surprise exploding center filled with red, white, and blue candies, perfect for 4th of July celebrations. Moist, flavorful, and easy to make, this cake is a guaranteed crowd-pleaser.
Line the candy cavity with parchment paper to prevent leakage. Use room temperature eggs and butter for better batter aeration. Warm the milk before mixing to avoid lumps. Chill the cake for 20 minutes before frosting if it sinks slightly after adding candy. Cut the cake slowly with a sharp serrated knife to avoid candy spillage. For gluten-free, substitute flour with a 1:1 gluten-free baking blend; for dairy-free, use coconut oil and almond milk.
