Description
This dark chocolate raspberry coffee cake is soft and moist with a buttery almond streusel on top. There’s plenty of different size baking pans you can use, so review my recipe notes before beginning.
Ingredients
Streusel
- 1/4 cup (50g) granulated sugar
- 1/4 cup (31g) all-purpose flour (spooned & leveled)
- 3 Tablespoons (43g) unsalted butter, cold
- 1/2 cup (64g) sliced or slivered almonds
Cake
- 2 cups (250g) all-purpose flour (spooned & leveled)
- 2 teaspoons baking powder
- 1/2 teaspoon salt
- 1/4 cup (4 Tbsp; 56g) unsalted butter, softened to room temperature
- 3/4 cup (150g) granulated sugar
- 1 large egg
- 1 teaspoon pure vanilla extract
- 1 cup (240ml) buttermilk or whole milk
- 1 cup (180g) dark chocolate chips*
- 1 and 1/2 cups fresh or frozen (do not thaw) raspberries
Instructions
- Preheat oven to 350°F (177°C). Spray a 9-inch baking pan* (see recipe note) with nonstick spray.
- Make the streusel first: Mix the sugar and flour together. Using a pastry cutter or fork, work the butter into the dry ingredients until the mixture resembles coarse crumbs. This takes a few minutes. Fold in the almonds. Set aside to use in step 4.
- Make the cake: Whisk the flour, baking powder, and salt together in a medium bowl. Set aside. In a large bowl using a handheld or stand mixer fitted with a paddle attachment, beat the butter and sugar together on medium-high speed until combined and creamy, about 1-2 minutes. Scrape down the sides and up the bottom of the bowl as needed. Add the egg and vanilla extract and beat until combined. Add the dry ingredients and begin beating on low speed. With the mixer running, slowly pour in the buttermilk. Finally, add the chocolate chips. Beat on low until everything is combined. Avoid over-mixing. Using a large spoon or silicone spatula, gently fold in the raspberries. They’ll break a little bit, but try to be extra careful.
- Spread the batter into the prepared baking pan. Top with the streusel. If you have any extras, dot the top of the cake with a few raspberries and chocolate chips.
- Bake for about 45-46 minutes if using an 8-inch or 9-inch baking pan, though that time changes if you used a different size baking pan. That time is a guideline; the cake is done when a toothpick inserted in the middle comes out clean. If the cake is browning too quickly on top, loosely tent with aluminum foil as it bakes.
- Remove from the oven and allow to cool for at least 10 minutes before slicing and serving. You can also let the cake cool completely before slicing and serving.
- Cover leftovers tightly and store at room temperature for 3 days or in the refrigerator for up to 1 week.
Notes
- Freezing Instructions: Freeze baked and cooled cake for up to 3 months. Thaw in the refrigerator or at room temperature before serving.
- Special Tools (affiliate links): 9-inch Square Baking Pan, 9-inch Pie Dish, 11×7-inch Baking Pan, or any similar 8- to 10-cup capacity baking dish | Glass Mixing Bowls | Pastry Cutter | Whisk | Electric Mixer (Handheld or Stand) | Silicone Spatula
- Cake Pan Sizes: You can bake this cake in a 9-inch square baking pan, a 9-inch pie dish, an 11×7-inch baking pan, or an oval baker that’s about 9-10 inches long. Anything that holds 8-10 cups of batter works. The bake time slightly changes, so keep your eye on the cake after about 42 minutes and have a toothpick handy to check for doneness. For a 9×5-inch loaf pan, bake for at least 60-65 minutes. For muffins, follow the same baking instructions as my blueberry streusel muffins. For a larger 9×13-inch cake, double the recipe. The bake time will be a little longer, but use a toothpick to test for doneness.
- Chocolate Chips: You can use milk chocolate, white chocolate, semi-sweet, or dark/bittersweet chocolate chips.
- Buttermilk: You can substitute whole milk for buttermilk if desired. Acidic buttermilk isn’t needed in order for the cake to rise since we’re using baking powder. However if you’d like the tangy flavor, you can make your own sour milk substitute. Add 2 teaspoons of white vinegar or lemon juice to a liquid measuring cup. Then add enough whole milk to the same measuring cup until it reaches 1 cup. (In a pinch, lower fat or nondairy milks work for this soured milk, but the cake won’t taste as rich.) Stir it around and let sit for 5 minutes. The homemade “buttermilk” will be somewhat curdled and ready to use in the recipe.
