How to Make Blackberry Cake with Coconut Cream Cheese Frosting Recipe
Step 1: Prepare the Cake Batter
Begin by greasing and flouring a 9×13 inch cake pan—this helps your cake come out cleanly. In a large bowl, combine the yellow cake mix, eggs, oil, and raspberry Jell-O gelatin. Use an electric mixer on high speed for about 2 minutes until everything is blended perfectly. This step is crucial to aerate the batter and kick-start the cake’s tender crumb.
Step 2: Fold in the Blackberries
Now for the fun part—gently fold in the frozen blackberries. The batter will feel thick and a bit stubborn, almost like a giant wad of bubblegum, but don’t be alarmed; this is exactly what creates those juicy pockets of blackberry goodness you love in every bite. Use a sturdy spatula to make sure the berries are evenly distributed without breaking them up too much.
Step 3: Bake the Cake
Pour the batter into your prepared pan, scraping every last bit out. Bake in a preheated oven at 350°F until a fork inserted in the center comes out clean, about 40 minutes. Don’t rush the cooling—let your cake sit until completely cooled. This resting time ensures the moisture settles and your cake won’t be overwhelmed by the frosting.
Step 4: Make the Coconut Cream Cheese Frosting
While the cake cools, start your frosting by beating the softened cream cheese and butter together until perfectly smooth. Gradually add the powdered sugar to sweeten and thicken the mixture. Stir in milk and a pinch of salt to balance the flavors and get the consistency just right. For that tropical kick, gently fold in coconut extract—this small addition really brings the frosting to life and complements the tart blackberries beautifully.
Step 5: Frost, Chill, and Serve
Spread the coconut cream cheese frosting liberally over your cooled cake. The frosting’s creamy texture pairs magnificently with the light cake, providing every bite a dreamy finish. Chill the frosted cake to set the frosting and help those flavors meld together. Then slice up and serve your masterpiece!
How to Serve Blackberry Cake with Coconut Cream Cheese Frosting Recipe

Garnishes
To elevate presentation and flavor, sprinkle fresh blackberries or toasted coconut flakes right on top of the frosting. A light dusting of powdered sugar creates an elegant snow-like finish. These little touches make your cake feel special and invite guests to dig in with anticipation.
Side Dishes
This cake is rich and flavorful enough to stand on its own, but if you’re aiming for an amazing dessert spread, consider pairing it with a scoop of vanilla bean ice cream or a refreshing citrus sorbet. The cool creaminess or bright acidity balances the cake’s sweetness perfectly.
Creative Ways to Present
Try serving individual slices with a dollop of whipped coconut cream for an extra boost of tropical bliss. You could also layer this cake in a trifle glass with extra berries and frosting to create a stunning parfait. Whether on a classic plate or presented in something unexpected, this recipe shines in every format.
Make Ahead and Storage
Storing Leftovers
Once frosted, cover the cake tightly with plastic wrap or place it in an airtight container. It will keep well in the refrigerator for up to 4 days, allowing those flavors to deepen even further.
Freezing
If you want to save a slice for later, cut the cake into individual pieces and freeze them wrapped in plastic wrap and foil. Frozen portions last up to 2 months and can be thawed in the fridge overnight for a delicious treat anytime.
Reheating
This cake is best enjoyed chilled or at room temperature, but if you prefer it slightly warm, invite the slice to sit at room temperature for 30 minutes before eating. Avoid microwaving as it could affect the texture of the frosting.
FAQs
Can I use fresh blackberries instead of frozen?
Absolutely! Fresh blackberries work beautifully and may even provide a brighter flavor, though frozen berries give the cake a slightly more uniform texture and deep color.
Is the coconut extract necessary?
The coconut extract is optional but highly recommended for that unique twist on the frosting. If you’re not a fan, simply leave it out and enjoy a classic cream cheese frosting.
Can I make this cake gluten-free?
To make a gluten-free version, substitute the yellow cake mix with a gluten-free mix of similar weight and follow the rest of the recipe as is. The blackberries and frosting components are naturally gluten-free.
How long does it take to prepare and bake?
Prep time is around 15 minutes, and baking takes about 40 minutes, making this a relatively quick dessert to whip up even on busy days.
What makes the frosting so creamy?
The combination of softened cream cheese and butter, beaten together until smooth, creates that rich, creamy texture that melts perfectly on the tongue. The powdered sugar ensures it’s thick enough to spread but never gritty.
Final Thoughts
Making this Blackberry Cake with Coconut Cream Cheese Frosting Recipe is like inviting a little celebration into your kitchen. The way the blackberries burst through the tender cake and the frosting wraps everything in smooth coconutty goodness is simply irresistible. I hope you enjoy baking and sharing this delightful dessert as much as I do!
