Rye Layer Cake with Roasted Raspberries & Coriander-Vanilla Buttercream

 

A dense, buttery rye cake with a tart, jam-like filling and toasted coriander buttercream. The nutty-sweet flavor of the coriander complements the bright flavor of the raspberries in a surprisingly perfect way. This cake is a project, but most of the components can be made the day before. There are five steps to making this cake's flavor extra special. 

Rye Cake with Roasted Raspberries & Coriander-Vanilla Buttercream

- step 1: make the cake - 

{can be made 1 day ahead}

Rye Cake

1 ½ cup sugar (300 grams)

2 cups all-purpose flour (240 grams)

1 cup whole rye flour (113 grams)

1 ½ tsp. baking powder

1 ½ tsp. kosher salt

1 tsp. ground coriander

1 ½ cups butter, softened

5 eggs

¾ cup heavy cream

2 Tbsp. apple cider vinegar

1 tsp. vanilla

Preheat the oven to 350°. Butter and flour a 9 inch springform pan and line the bottom with parchment paper. In a large mixing bowl, combine the flours, baking powder, salt and coriander. In the bowl of a stand mixer, combine the butter and sugar and beat until very smooth, about 4 minutes. Add the eggs, one at a time, beating after each addition. Add the flour mixture and the cream alternately and beat batter until smooth. Add the vinegar and vanilla and beat until incorporated. Transfer the batter to the prepared pan and smooth the top. Bake for 1 hour or until a toothpick inserted in the center comes out with just a few moist crumbs. The cake will be very dark. Let cool completely before removing from the pan.

- step 2: a milk soak to keep the cake moist -

Coriander Milk Soak

1 cup whole milk

¼ cup sugar

2 tbsp. coriander seeds

1 vanilla bean, split and seeded

{can be made 1 day ahead}

Vanilla-Coriander Buttercream

4 Tbsp. coriander seeds

2 cups (4 sticks) unsalted butter

8 oz. cream cheese, softened

4 cups powdered sugar

1 Tbsp. heavy cream

2 tsp. vanilla extract

In a medium saucepan, melt butter and 4 Tbsp. coriander seeds and let cook over medium heat until butter is lightly browned and fragrant, about 10 minutes. Let cool for 10 minutes and then strain out the coriander seeds. Discard seeds and let butter cool completely. Refrigerate until cold.

Using an electric mixer, beat the cold brown butter until smooth. Add the cream cheese and beat until combined. Add the powdered sugar and slowly beat until completely smooth. Add the cream and vanilla and beat again until incorporated.

- step 4: roast the raspberries -

{plan to make the day of}

Roasted Raspberry Filling

3 pints Driscolls Raspberries

½ cup sugar

Preheat the oven to 300 degrees. Line a baking sheet with parchment paper. Place the raspberries on the baking sheet and sprinkle the sugar over top. Bake for 45 minutes to 1 hour, stirring every 15 minutes. The raspberries should cook down into a jam-like paste. Cool completely.

- step 5: assemble the cake -

1 Tbsp. coriander seeds

Fresh raspberries for garnish

Cut the cake into two layers with a long bread knife. Using a pastry brush, brush a generous amount of the milk soak onto both cut sides of the cake layers. Let soak in for a few minutes. Spread a layer of the buttercream over the bottom cake layer, and using a pastry bag pipe a band of frosting around the edges of the cake in a ring. This is to hold the raspberry filling in. Spread the roasted raspberry filling onto the middle of the cake to create an even layer. Place the other cake layer on top. Brush some more of the milk soak onto the top of the cake and let soak in for a few minutes. Spread a thin layer of buttercream over the entire cake as a crumb coat. Refrigerate the cake for 30 minutes to 1 hour, or until the crumb coat is firm. Finish icing the cake with the remaining buttercream. Heat a dry skillet over medium heat and add the coriander seeds, swirling the pan until seeds are fragrant and toasted, about 1 minute. Remove from heat and let cool completely. Lightly crush with the side of a knife on a cutting board or pulse once or twice in a spice grinder. Garnish the top of the cake with the coriander. Serve the cake with fresh raspberries on the side.
