There’s something about a poke cake that just feels like summer. Maybe it’s the way the gelatin soaks into every crumb, or how the whipped topping melts slightly on a warm afternoon. This Coconut Raspberry Poke Cake brings together tart raspberry, creamy Cool Whip, and sweet coconut for a dessert that’s impossible to resist. I made it for a family gathering last month, and let me tell you, the pan was empty before I could even grab a second slice.

What makes this recipe shine is how simple it is. You start with a box of white cake mix, which keeps things light and fluffy. Then comes the magic: raspberry gelatin poured into poked holes, a layer of warm raspberry preserves, and finally that cloud-like Cool Whip finished with toasted coconut. It’s the kind of dessert that looks fancy but takes minimal effort. Perfect for potlucks, birthdays, or when you need a crowd-pleaser without the stress.

Why This Coconut Raspberry Poke Cake Works

The balance of flavors is what sets this apart. The tartness from the raspberry cuts through the sweetness, while the coconut adds a tropical note that makes every bite feel like a mini vacation. Plus, the texture is incredible. The gelatin keeps the cake moist for days, and the Cool Whip stays light and fluffy if you keep it chilled. It’s one of those recipes that actually tastes better the next day, which is rare for a cake.

Ingredients You’ll Need

Everything here is simple to find at your local grocery store. The white cake mix is the base, and you’ll need the ingredients listed on the box (usually eggs, oil, and water). The raspberry gelatin is key for that signature poke cake moisture. Raspberry preserves add a concentrated fruit layer, and the Cool Whip keeps things light. Shredded coconut is the final touch, and toasting it lightly makes all the difference.

1 box white cake mix (plus ingredients listed on box: eggs, oil, water)
1 box raspberry flavored gelatin (3 oz size)
2 cups hot water
1 jar raspberry preserves (10 oz)
1 tub Cool Whip, thawed (8 oz)
1 bag shredded sweetened coconut (7 oz)

Step-by-Step Instructions

Start by preheating your oven and preparing the cake batter according to the package directions. Pour it into a greased 9×13 pan and bake until a toothpick comes out clean. Let it cool completely. This is important. If the cake is even a little warm, the gelatin will melt the Cool Whip later and things get messy.

Once cooled, grab a wooden spoon and poke holes all over the surface. You want them about an inch apart, pressing down halfway through the cake. Don’t be shy with the holes. The more you poke, the better the gelatin soaks in. Dissolve the raspberry gelatin in 2 cups of hot water, stirring until completely clear. Pour it slowly over the cake, making sure it fills all the holes. It will look like a lot, but the cake absorbs it beautifully.

Microwave the raspberry preserves for about 30 seconds to make them spreadable. Use a spatula to create an even layer over the top. Then spread the Cool Whip gently, starting from the edges and working inward. Finally, sprinkle the shredded coconut on top. For extra flavor, toast the coconut in a dry pan for 2 to 3 minutes until golden.

Pro Tips for Best Results

Cool the cake completely before poking holes to prevent crumbling
Use hot, not boiling, water for the gelatin to avoid melting the cake
Warm preserves in 15-second intervals to avoid burning
Toast coconut for 2 to 3 minutes in a dry skillet for nutty flavor
Chill at least 4 hours, ideally overnight for best flavor

Variations to Try

Feeling creative? Swap the raspberry gelatin for strawberry or lime for a different twist. Fresh raspberries or sliced strawberries on top add a pop of color and freshness. If you prefer richer topping, use homemade whipped cream with a bit of vanilla. Some bakers even drizzle melted white chocolate over the coconut for a decadent finish.

Troubleshooting Tips

If your gelatin isn’t soaking in, poke more holes. If the preserves are too thick, microwave in 10-second bursts. If the Cool Whip slides off, make sure the preserve layer isn’t too warm. And if the coconut burns while toasting, start fresh and watch it like a hawk. It goes from golden to burnt fast.

Ingredient Substitutions

Cake mix: Yellow or vanilla cake works too
Coconut: Use unsweetened if you prefer less sugar
Cool Whip: Whipped cream or Greek yogurt mixed with whipped cream
Preserves: Raspberry jam or seedless raspberry sauce

Storage and Serving

Keep this cake refrigerated in an airtight container for up to 4 days. It actually improves after a night in the fridge. For longer storage, freeze individual slices wrapped in plastic, then thaw in the fridge overnight. Serve chilled with fresh berries, a scoop of vanilla ice cream, or alongside iced coffee or sparkling lemonade.

Frequently Asked Questions

Can I use a different gelatin flavor? Yes, strawberry or cherry work well. Just keep the raspberry preserves for consistency.

Do I have to toast the coconut? No, but it adds a nice nutty depth. Skip it if you prefer the soft texture.

Can I make this gluten-free? Use a certified gluten-free white cake mix and check all other labels.

How far ahead can I make this? Up to 2 days ahead is perfect. The flavors meld beautifully.

Can I use fresh raspberries instead of preserves? Yes, but cook them down with a bit of sugar first to create a sauce-like consistency.

Why is my cake too wet? You may have used too much water for the gelatin. Stick to 2 cups hot water exactly.

Can I use a different pan size? A 9×13 is ideal. Smaller pans will make the cake thicker and may need more baking time.
