Equipment
- Stand mixer
- 9-inch Springform Pan
- wire cooling rack
Ingredients
- 1 1/2 cups all-purpose flour Provide structure and bulk to the cake batter, creating the framework that holds moisture and crumb together. Combine with leavening and liquids to form a tender crumb while absorbing flavors. Sift or whisk to ensure even distribution and prevent lumps.
- 1 1/2 teaspoons baking powder Lighten and leaven the cake by producing carbon dioxide when activated, helping the cake rise and become airy. Distribute evenly through the dry ingredients to ensure consistent lift during baking. Measure precisely to avoid over-risen or dense texture.
- 1/2 teaspoons salt Enhance overall flavor balance and strengthen gluten slightly for improved texture while controlling sweetness. Work with baking powder to fine-tune the chemical leavening environment for predictable rise. Use sparingly to maintain proper seasoning and avoid a metallic taste.
- 6 tablespoons unsalted butter at room temperature Add richness and tenderness by coating flour proteins and contributing to a moist, melt-in-the-mouth texture. Cream with sugar to incorporate air for a lighter crumb and help set structure during baking. Use at room temperature to blend smoothly for even distribution.
- 1 cup granulated sugar Provide sweetness and contribute to cake tenderness while aiding in browning during baking for an appealing crust. Crease with butter during creaming to trap air and build volume in the batter. Adjust slightly if using very sweet add-ins like sweetened coconut or berries.
- 1 large egg Bind ingredients and add richness, contributing to structure and moisture through coagulation as the cake bakes. Whisk into the batter until just incorporated to maintain tenderness and avoid overmixing. Use at room temperature for even emulsification with fats.
- 1/2 cup coconut milk Contribute moisture, subtle coconut flavor, and fat that tenderizes the crumb while enhancing richness. Emulsify with butter and egg to create a smooth batter and aid in even baking. Stir gently to combine while preserving batter aeration.
- 1/2 teaspoon vanilla extract Add aromatic sweetness and depth, enhancing the overall vanilla notes and rounding out flavors in the cake. Mix into wet ingredients to distribute the aroma evenly without overpowering delicate components like raspberries. Use pure extract for best clarity of flavor.
- 1/2 teaspoon coconut extract Provide concentrated coconut aroma and flavor to intensify tropical notes without extra liquid. Combine with vanilla to create a layered coconut profile that complements the coconut milk and flaked coconut. Use sparingly to avoid artificial or overpowering taste.
- 3/4 cups sweetened flaked coconut Contribute chewy texture and rich coconut flavor to the cake, adding both mouthfeel and toasty notes after baking. Fold gently into batter to ensure even distribution and to avoid crushing delicate raspberries. Toast lightly beforehand if wanting deeper flavor, but incorporate as specified.
- 1 cup raspberries fresh or frozen Add bright, tart flavor and juiciness that contrasts with sweet coconut and buttery cake, contributing color and freshness. Fold in gently, especially if frozen, to prevent color bleed and maintain berry integrity. Adjust placement in batter to keep berries suspended rather than sinking.
- 1/4 cup all-purpose flour Serve as the dry base for the streusel topping, helping create a crumbly texture that contrasts the soft cake. Combine with brown sugar and coconut to bind when worked with cold butter pieces. Use measured amount to achieve a balanced streusel coverage without overwhelming the cake.
- 1/3 cup brown sugar Impart deep caramel-like sweetness and moistness to the streusel, complementing coconut and balancing tart raspberries. Mix with flour and coconut to create cohesive crumbs when cut with cold butter. Pack lightly if using natural or dark varieties to control intensity.
- 1/3 cup sweetened flaked coconut Add extra coconut flavor and crisp texture to the streusel topping, reinforcing the tropical theme and providing crunchy contrast. Combine with flour and brown sugar to build flakes into crumbs that brown attractively in the oven. Sprinkle evenly for consistent topping distribution.
- 4 tablespoons cold butter cut into pieces Create the streusel's tender, sandy texture by cutting cold butter into dry ingredients until pea-sized pieces form, yielding crisp, golden crumbs when baked. Keep chilled pieces to prevent melting prematurely and ensure distinct crumb clusters. Use exactly as specified for ideal topping consistency.
Instructions
- Preheat oven to 350 degrees F. Butter a 9-inch springform pan or pie pan. Set aside.: You will sense warm air fill the oven as it reaches 350 degrees F , and you want a consistently hot environment so the cake begins to rise the moment it goes in. Greasing the pan ensures the edges release cleanly, and a springform pan gives neat sides, while a pie pan will produce a slightly shallower cake. Tap the pan after buttering to distribute it evenly, then dust lightly with flour if you prefer an extra release layer. A common mistake is putting the cake into an oven that is still warming, which can yield uneven rise and a dense center, so wait until the oven signals it has reached temperature.
- Whisk together flour, baking powder, and salt in a medium bowl. Set aside.: As you whisk the all purpose flour with baking powder and salt , watch the fine powder cloud up briefly and then settle into a homogenous mixture. Sifting or whisking aerates the flour slightly, which helps the batter hold air and produce a tender crumb. Mixing the dry ingredients first also ensures the leavening is evenly distributed, preventing pockets of metallic tasting baking powder. Avoid over whisking to the point of compressing the mix, and be wary of measuring flour too firmly, as too much will dry the cake.
- In the bowl of a stand mixer, beat the butter and sugar until pale and fluffy, about 3 minutes. Add in egg, coconut milk, vanilla, and coconut extract. Mix until combined.: When you cream the unsalted butter with granulated sugar , look for a pale, ribbon like texture where the sugar has dissolved and tiny air pockets form; this is the backbone of a light cake. Adding the egg and liquids like coconut milk will momentarily deflate the mixture but then re emulsify into a smooth batter. The aroma will lift as you add the extracts, with the coconut extract sharpening the tropical notes and the vanilla extract smoothing the backdrop. A very common error is adding an egg that is too cold which can cause the batter to curdle, so bring ingredients to room temperature if possible.
- Gradually mix in the dry ingredients. Stir in the coconut. Transfer batter to prepared pan. Arrange raspberries on top of batter and slightly press them down.: As you fold in the dry mix, you will notice the batter turning from glossy to a thicker, matte finish; stop when streaks disappear to keep the crumb tender. Folding in sweetened flaked coconut adds flecks and little chewy pockets, which you will see distributed through the batter. Spoon the batter into the prepared pan and level gently; then scatter the raspberries across the top so they peek out after baking. Press each berry down slightly so it nests into the batter, preventing them from floating or burning on the surface. Resist the temptation to overmix at this stage, which can make the cake tough.
- To make the coconut streusel topping, in a small bowl combine flour, brown sugar, and coconut. Add in butter pieces and mix together with your fingers until crumbly. Top the cake with coconut streusel.: Rub the cold butter pieces into the streusel mixture until it forms coarse crumbs; you will feel pea sized bits that will bake into crisp clusters. The brown sugar gives a molasses aroma when warmed, and the extra sweetened flaked coconut will toast on top creating a golden, fragrant crust. Scatter the streusel evenly and avoid pressing it into the batter, as you want distinct crunchy pockets. A frequent slip is overworking the butter into a paste, which produces a gummy topping rather than crumbly bits.
- Bake cake for 45-50 minutes or until it is golden brown and firm to the touch. Let cool in pan for 15 minutes. Remove from pan and cool completely on a wire cooling rack. Cut into slices and serve.: As the cake bakes, the kitchen will fill with toasty coconut and caramelized sugar scents, and the top should take on an even golden brown color. A gentle jiggle in the center that returns slowly indicates doneness, along with a toothpick coming out mostly clean with a few moist crumbs. Letting it rest in the pan for about 15 minutes allows the structure to set, making it easier to release, and transferring to a wire cooling rack prevents steam from sogginess as it cools. Avoid slicing while hot, which can make the cake crumble or smear; patience yields cleaner slices.
- Note - the cake will keep up to 2 days, stored in an air-tight container on the counter.: Resting and storing the cake allows flavors to meld and the texture to mellow slightly, creating perfect slices for the next day. Keep it room temperature in an air tight container to protect the streusel from softening from humidity. If you live in a very hot climate, brief refrigeration is acceptable but may firm the coconut and change the mouthfeel. A common issue is leaving the cake uncovered, which dries out the crumb quickly, so always seal it properly.
Notes
- Room temperature ingredients: Bringing the butter and egg to room temperature helps them blend smoothly and creates a uniform batter that traps air for a lighter crumb.
- Measure flour properly: Spoon all purpose flour into the cup and level it to avoid packing, which can make the cake dense and dry.
- Fresh leavening matters: Check the baking powder date and replace if it has been sitting for more than six months to ensure a reliable rise.
- Protect frozen berries: If you use frozen raspberries, leave them partially frozen and toss them in a bit of all purpose flour to keep them from bleeding into the batter.
- Don’t overwork the streusel: Work the cold butter into the topping just until pea sized crumbs form, otherwise it will turn paste like and lose its crispness.
- Test for doneness: Insert a toothpick in the center toward the end of the bake time; a few moist crumbs are fine, but wet batter means it needs more time.
