Step 6: Alternate the Flour and Buttermilk
Add approximately one-third of the dry ingredients to the butter mixture and mix gently.
Add half of the buttermilk and mix again.
Continue alternating:
Dry ingredients → buttermilk → dry ingredients → remaining buttermilk → remaining dry ingredients
Mix only until the ingredients are combined.
Avoid overmixing because excessive mixing can develop the gluten in the flour and make the finished cake less tender.
Step 7: Fold in the Tropical Ingredients
Add the drained pineapple and shredded coconut to the batter.
Gently fold them in with a spatula.
Next, carefully fold in the raspberries.
If you are using frozen raspberries, there is no need to thaw them first. Folding them in while frozen can also help reduce excessive bleeding of raspberry juice into the batter.
Try not to stir aggressively. You want the raspberries to remain mostly intact.
Step 8: Prepare the Coconut Topping
For the optional topping, place the flour, brown sugar, shredded coconut, and cold butter in a small bowl.
Use your fingertips or a pastry cutter to work the butter into the mixture until coarse crumbs form.
The mixture does not need to be perfectly uniform. Small pieces of butter scattered throughout the topping will create a pleasant crumbly texture as it bakes.
Step 9: Transfer the Batter to the Pan
Pour the batter into the prepared pan.
Use a spatula to gently spread it into an even layer.
Scatter the coconut crumb topping over the surface.
If a few raspberries are visible near the top, that is completely fine and will make the finished cake look even more inviting.
Step 10: Bake the Cake
Place the pan in the preheated oven and bake for approximately 40–50 minutes.
Because ovens and pans vary, begin checking the cake around the 40-minute mark.
The cake is ready when:
- The top is lightly golden.
- The center looks set rather than wet.
- A toothpick inserted into the center comes out clean or with a few moist crumbs.
- The edges have begun to pull slightly away from the pan.
If the top begins browning too quickly while the center still needs time, loosely cover the cake with aluminum foil and continue baking.
Step 11: Let It Cool
Remove the cake from the oven and allow it to cool in the pan for approximately 15–20 minutes.
Then carefully transfer it to a wire rack to cool further.
Although it can be tempting to slice it immediately, allowing the cake to cool gives the crumb time to settle and makes it easier to cut cleanly.
Step 12: Slice and Serve
Once slightly warm or completely cooled, slice the cake into wedges or squares.
For breakfast, serve it alongside coffee, tea, or a glass of cold milk.
For brunch, you can add fresh raspberries and a few pineapple pieces to the serving plate for a colorful presentation.
A light dusting of powdered sugar is another simple finishing touch if you prefer a sweeter presentation.
Helpful Tips for the Best Cake
Drain the Pineapple Well
This is one of the most important details in the recipe. Excess pineapple juice can add too much moisture to the batter.
Don’t Overmix
Once the flour is added, mix only until everything comes together. A few small streaks of flour are better than an overworked batter.
Toss Fresh Raspberries in Flour
If your raspberries are particularly juicy, you can gently toss them with a teaspoon or two of the measured flour before folding them into the batter. This can help distribute them throughout the cake.
Use Room-Temperature Ingredients
Softened butter and room-temperature eggs combine more smoothly and help produce a more uniform batter.
Watch the Baking Time
Fruit-filled cakes can vary in baking time depending on how much moisture the fruit contains. Use the toothpick test rather than relying solely on the clock.
Fresh or Frozen Raspberries?
Both work well.
Fresh raspberries provide a delicate texture and bright appearance.
Frozen raspberries are convenient and can be used directly from the freezer. Avoid thawing them first, since thawed berries can release a considerable amount of liquid into the batter.
If using frozen raspberries, fold them into the batter gently and expect the cake to potentially need a few extra minutes in the oven.
Easy Serving Ideas
This breakfast cake is delicious on its own, but you can make it feel even more special with a few simple additions.
Try serving it with:
- A spoonful of plain or vanilla yogurt
- Fresh raspberries
- Toasted coconut
- A small drizzle of honey
- Powdered sugar
- Fresh pineapple
- A cup of coffee or tea
For a brunch gathering, cut the cake into smaller squares so guests can easily enjoy a piece alongside other breakfast dishes.
How to Store It
Once completely cooled, cover the cake tightly and keep it at room temperature for up to 2 days.
For longer storage, refrigerate it in an airtight container for several days. Allow individual pieces to come closer to room temperature before serving, or warm them gently for a softer texture.
The cake can also be frozen. Wrap individual portions securely and place them in a freezer-safe container. Thaw overnight in the refrigerator or allow them to thaw at room temperature before serving.
