What Is Scharffen Berger Chocolate?
It's important to use high quality ingredients in order to create a dark and flavorful chocolate cake, and that's why I love using Scharffen Berger Chocolate.
Their chocolate is made bean-to-bar, which means it's crafted on-site in Ashland, Oregon (my home state!) from roasting the beans to forming the bars.
This process really highlights the true flavors of the cacao, which comes through in the deep, complex and delicious taste.
That's why I used Scharffen Berger Dark Chocolate Cocoa Powder in the cake batter and their 70% Bittersweet Dark Chocolate Baking Bar for the chocolate ganache topping.
Ingredients Needed
Here are some notes on the ingredients we'll be using. For the full ingredients list, look at the recipe card below.
- Scharffen Berger Dark Chocolate Cocoa Powder: This really enhances the deep and dark chocolate flavor in the cake.
- Leavening Agents: Both baking soda and baking powder are used.
- Milk: I used 2% milk, but you can use whatever milk you prefer.
- Oil: You can use either vegetable or canola oil.
- Blackberries: Use fresh blackberries, not frozen.
- Baking Chocolate: I used a 4 ounce bittersweet chocolate bar. You could also use milk chocolate.
- Heavy Whipping Cream: This is used to make the ganache.
Instructions
Here are the step by step instructions on how to make this chocolate and blackberry cake.
Step 1: Dry ingredients. In a large bowl, whisk together the flour, cocoa powder, sugar, baking soda, baking powder, and salt.
Step 2: Wet ingredients. In a medium-sized mixing bowl, whisk together the warm water, milk, eggs, vegetable oil, and vanilla extract until combined.
Step 3: Combine the ingredients. Slowly add the wet ingredients into the dry, whisking until a wet batter forms.
Step 4: Bake. Divide the chocolate batter amongst the three prepared cake pans and bake for 23-28 minutes, or until a toothpick inserted into the middle of the cakes come out clean.
PRO TIP! To easily remove the cakes from their pans, turn the cake pan upside down on top of a cooling rack and hit the top of the pan. It should easily slide out!
Blackberry Buttercream Frosting
In a blender or food processor, pulse the blackberries until pureed. Press through a fine-mesh strainer over a small bowl and discard the seeds.
In a large bowl of a stand mixer using the paddle attachment, beat he butter until light and creamy.
Add the powdered sugar and vanilla extract and mix on low until combined. Then add the blackberry puree and beat on high speed for 1-2 minutes until smooth and creamy.
Chocolate Ganache
In a microwaveable-safe bowl, heat the heavy whipping cream until bubbling.
Pour the heavy cream over the chopped chocolate (that's in a small bowl) and allow it to sit for 3 minutes. Whisk together until smooth.
Cool to room temperature.
Assembling The Cake
Make sure the cake layers are completely cooled before assembling and decorating.
First, level off the tops of each cake layer to create a flat surface using a serrated knife.
Place one cake layer on a cake stand or plate and spread about ⅔ cup of frosting (I use my offset spatula to make it easier).
Repeat with the second layer. Top the cake with the last layer and spread on about ¼ cup of frosting. Frost and smooth the outside of the cake with a thin crumb coat.
Place the entire cake in the refrigerator or freezer for 10 minutes to chill.
Finish frosting the cake with the remaining buttercream, pour on the chocolate ganache, and top with fresh blackberries.
Recipe Variations
- Homemade Blackberry Jam: If you want to fill the cake with a blackberry jam, follow this recipe. Just swap out the raspberries for blackberries.
- Fresh Berries: Don't have blackberries? You could easily substitute them for a different berry, like raspberries or strawberries.
Storage Tips
Keep any leftover cake slices in an airtight container in the refrigerator for up to 5 days.
You could also wrap each individual cake slice in plastic wrap before placing it into the refrigerator. This helps the cake to not dry out.
Expert Baking Tips
- Cake Pans: For this recipe I used three 6-inch cake pans. Prepare each cake pan by lining them with parchment paper and then non-stick spray.
- Measuring Flour: To help ensure you don’t add extra flour, follow these three simple steps: 1) Fluff up the flour using a fork. 2) Spoon the flour into your measuring cup. 3) Scrape a knife across the top of the measuring cup to level out the flour.
- Chocolate Ganache: Do not make the chocolate ganache until you are ready to assemble the cake. If you make it too soon, it can become too thick.
- Crumb Coat: This is where we add a thin layer of frosting on the cake in order to catch the crumbs and keeps them secure. You’ll want to chill the cake in the refrigerator or freezer for 10 minutes after the crumb coat has been put on before the final frosting layer.
- Cake Decorating Tools: I like to use a turntable, cake scraper, and an icing spatula to help assist me when assembling a cake.
Recipe FAQs
I used three 6-inch cake pans, but you could also use two 8-inch or two 9-inch cake pans.
The combination of dark chocolate and sweet blackberries make each bite of this cake incredible. So yes, blackberries certainly go well with chocolate!
I do not recommend using frozen blackberries. Use fresh.
