In a large jug, whisk together the buttermilk, oil, eggs, and vanilla extract.
¾ teaspoon Vanilla Extract, 2 Eggs, 1 cup Buttermilk, ½ cup Vegetable Oil
Slowly pour in the ingredients from the large jug and mix until just combined.
Slowly add the hot water and mix. Your batter will be very thin and it makes a lot of cake batter!
1 cups Very Hot Water
Pour the batter into the prepared pans. Bake for 35-40 minutes, until a toothpick comes out clean when inserted
Allow the cakes to cool for 10 minutes before removing from the pans. Let them cool completely on a cooling rack.
Strawberry Chocolate Ganache
Blend fruit in a blender until completely smooth. Strain it through a sieve into a bowl so you remove all the seeds (or leave them if you aren't that bothered by seeds!)
½ cup Fresh Strawberries
Place the chopped chocolate and pureed fruit into a large bowl.
4 oz Dark Chocolate
Put the cream in a saucepan on the stove and bring to a simmer. Remove from heat.
½ cup Heavy Cream
Pour over the chocolate. Whisk until smooth, then add the butter and whisk again. Let cool completely, this took about 30 minutes for me but it might take longer in the summer!
1 ½ tablespoons Butter
Strawberry Buttercream
Blend the freeze dried strawberry pieces with a food processor or blender until you have a fine powder. Set aside.
1 ½ cups Freeze Dried Strawberries
In a stand mixer fitted with the paddle attachment, or in a large bowl with a handheld mixer, beat the butter and confectioners' sugar on low speed.
1 ½ cups Unsalted Butter, 4 ¼ cups Confectioner's Sugar
Once combined, turn the speed to medium-high and beat until it becomes very thick.
Stop the mixer and add the vanilla extract, salt and strawberry powder. Beat on medium-high speed until light and fluffy.
1 ½ teaspoons Vanilla Extract, ¼ teaspoon Kosher Salt
Turn the mixer on your lowest speed and slowly pour in the cream until the frosting becomes creamy and spreadable - you might not need all the cream!
¼ cup Heavy Cream
Assemble
Place one cake layer down on your cake stand or plate. Place some of the frosting in a piping bag fitted with a round tip. Pipe frosting around the edge of the cake.
Scoop out the strawberry ganache and use a small offset spatula to spread it around, inside the border.
Place the second layer on top.
Frost the sides and top of the cake with the remaining frosting. I also piped some swirls using a 1M Wilton baking tip, then you can decorate with fresh strawberries, chopped chocolate, or chocolate covered strawberries!
Notes
My recipes have been developed and tested in metric grams. I highly recommend using a weighing scale and measuring out your ingredients the metric way. I have provided a conversion to US cups but please note that I haven’t tested the recipe with this method. Just click on ‘US Customary’ above the ingredients to see the cup measurements.
I make sure that all of my ingredients are at room temperature before I start the recipe, so pull out all of the ingredients before you start baking.
Salt: If you don’t have kosher salt, halve the amount of salt called for in the recipe. 1 teaspoon kosher salt = ½ teaspoon fine salt. I'm using Diamond Crystal kosher salt, Morton Salt is much saltier!
Buttermilk: If you don’t have buttermilk, replace it with an equal amount of sour cream or full fat yogurt. You can also make your buttermilk, for every cup of buttermilk add 1 tablespoon of lemon juice to 1 cup of milk and let sit for 5 minutes.
Chocolate: I recommend using dark chocolate (around 60-70% cocoa) or semisweet chocolate. Milk chocolate and white chocolate won't work with the amounts listed because the ratios will be off. I don't recommend using chocolate chips because those contain emulsifiers.
Vegetable Oil: Use an unflavoured oil like canola oil or sunflower oil if you don’t have vegetable oil.
Storage: Keep tightly wrapped in the fridge for up to 5 days. Let it come to room temperature before eating.
Making Ahead: You can make the cake layers ahead of time. Bake them and then once completely cooled, wrap them in plastic wrap tightly. Store in the fridge for up to 2 days or in the freezer for up to 2 months. If frozen, allow to defrost and come to room temperature before frosting the cake.
