Treat yourself to this divine White Chocolate Raspberry Poke Cake, where soft white cake blends with creamy white chocolate ganache and tangy raspberry sauce. Each piece shows off beautiful strips of sweet and fruity fillings, finished with smooth white chocolate mousse and juicy raspberries.
I first baked this cake on Mother's Day, and the mix of white chocolate with raspberry turned out so fancy that it's now what I make for all big events. The way the fillings soak into the cake makes it super moist and packed with flavor.
Quality Ingredients Matter
- White cake flour: Makes the cake incredibly soft and light
- Egg whites: Help you get that pure white look and airy feel
- White chocolate: Get the good stuff with real cocoa butter
- Fresh raspberries: Look for plump, deep red ones for best taste
- Heavy cream: Don't skimp on fat content or your mousse won't set right
- Sour cream: Keeps your cake base moist and rich
Wonderful Creation Steps
- Base Prep:
- Beat butter until fluffy then slowly mix in sugar until it's light and airy
- Adding Egg Whites:
- Carefully mix in the whipped egg whites without losing their fluffiness
- Getting Moisture Right:
- Switch between adding dry items and wet stuff like milk and sour cream
- Making Holes:
- After it cools down, poke even holes all over the cake
- Adding Fillings:
- Pour white chocolate ganache and raspberry sauce in rows
- Topping It Off:
- Cover with white chocolate mousse using wavy strokes

I've got to say, the white chocolate mousse on top is what I love most. It feels so smooth against the soft cake underneath, and my family always argues about who gets the edge pieces with extra mousse.
Gorgeous Serving Ideas
Add fresh raspberries, white chocolate shavings, and drizzle extra sauce on top for a fancy look that'll wow everyone at special events.
Tasty Twists
Switch things up by using other berries like strawberries or blackberries, or go all out with a three-chocolate version using dark and milk chocolate too.
Staying Yummy
Keep it covered in the fridge for up to three days. Let it sit out for about 15 minutes before you serve it so the texture's just right.
I've learned while making this cake that sometimes the most wow-worthy desserts come from doing simple things really well. Those perfect filling stripes always get gasps from guests, making each slice bring tons of happiness.
