Method
Bake the cake
- Prepare and bake the white cake mix according to package directions in a 9×13-inch pan, using the ingredients listed on the box. Bake until a toothpick inserted in the center comes out clean, as directed on the box.
- Let the cake cool for 10 minutes in the pan before poking holes. The surface should be warm but not hot to the touch.
Add raspberry poke filling
- Use the handle of a wooden spoon to poke holes evenly across the cake, spacing them consistently. Poke down far enough that the holes reach near the bottom layer without breaking the cake apart.
- Heat the raspberry preserves and water together until smooth, stirring as they warm. Bring to a gentle simmer and cook just until fully loosened and glossy.
- Pour the raspberry mixture over the cake, allowing it to fill the holes. Use a spoon to help distribute if needed so most holes get filled.
Make the white chocolate pudding layer
- Whisk together the instant white chocolate pudding mix and cold milk until slightly thickened. Continue whisking until it looks smooth and thick enough to spread.
- Spread the pudding evenly over the cake, smoothing the top to the edges. Work quickly so the pudding doesn’t set too firm.
- Refrigerate the cake for at least 1 hour. Chill until the pudding layer is set and the cake feels firm.
Top and finish
- Fold the melted and cooled white chocolate into the whipped topping. Mix just until uniform with no white chocolate streaks.
- Spread the whipped topping mixture over the chilled cake. Cover the surface evenly for clean edges.
- Garnish with fresh raspberries and white chocolate shavings. Place raspberries across the top and sprinkle shavings last for visible texture.
- Chill until ready to serve. Keep refrigerated until serving for the best sliceable texture.
Notes
Pro tip: Cool the melted white chocolate before folding so it doesn’t deflate the whipped topping. Refrigerate leftovers in an airtight container up to 3 days (best texture within 48 hours); freeze is not recommended because the whipped topping and berries can weep upon thawing. For a lighter option, use sugar-free instant pudding mix and reduced-sugar raspberry preserves if you want less sweetness.
