Chocolate and Salted Caramel Layer
Cake
Yields: 1 2-layer 9-inch cake
Ingredients:
For the Cake:
2 C. All-purpose flour
1 ½ C. Sugar
¾ C. Unsweetened cocoa powder
2 tsp. Baking soda
¼ tsp. Salt
1 C. Water
¾ C. Buttermilk
¾ C. Vegetable oil
3 Eggs
For the Ganache:
18 oz. Dark chocolate, chopped (do not
exceed 61% cacao)
2 ¼ C. Heavy cream
For the Salted Caramel:
¼ C. Sugar
2 Tbsp. Water
¼ C. Heavy cream
1 tsp. Vanilla
Split caramel in half and add 1/8 tsp.
Salt to half
For the Salted Caramel
Buttercream:
To second half of caramel, add ¾ stick
of salted butter (or 3/4 stick of unsalted butter and 1/8 tsp. of salt)
1 C. Powdered sugar
1.
Position racks in
the top and bottom third of the oven; preheat to 350 degrees F. Coat two 9-inch
springform pans with nonstick spray. Line bottoms with parchment rounds; spray
top of rounds.
2.
Sift flour,
sugar, cocoa powder, baking soda, and salt into a large bowl. Whisk to blend
and form well in the center. Whisk 1 C. water, buttermilk, oil, and eggs in
medium bowl to blend. Pour wet ingredients into well in dry ingredients; whisk
just to blend, don’t over-whisk. Divide cake batter between prepared pans
(about 3 cups each).
3.
Bake cakes until
tester inserted in center comes out clean, about 30 minutes. (If cakes form
domes, place kitchen towel atop hot cakes, then press gently with the palm of
your hand to level.)
4.
Cool completely
in pans on cooling racks.
*** Cakes can
be made 1 day ahead. Cover cakes in pans and let stand at room temperature.
1.
Place chopped
chocolate in a medium bowl. Bring cream just to boil in heavy medium saucepan.
2.
Pour cream over
chocolate.
3.
Let stand 1
minute, then stir until ganache is melted and smooth.
4.
Transfer 1 ¼ C.
ganache to a small bowl. Cover and refrigerate until ganache is thick enough to
spread, stirring occasionally, about 1 hour. Let remaining ganache stand at
room temperature to cool until barely lukewarm.
For the Salted Caramel:
1.
Briefly stir
together sugar and water in a small saucepan and bring to a boil over
medium-high heat.
2.
Continue cooking,
without stirring, until mixture turns dark amber in color, about 6 to 7
minutes.
3.
Remove from heat
and slowly
add in cream and vanilla (start with a tablespoon or two), stirring
with a wooden spoon until completely smooth. Split evenly into two bowls and
set aside until cool to the touch, about 25 minutes.
*** Keep a
close eye on the caramel as you make it. It goes from clear bubbles to the
“amber” color within about 30
seconds, and then will burn pretty quickly thereafter.
4.
Mix in 1/8 tsp.
salt to one bowl.
For the Salted Caramel Buttercream:
1.
Beat the butter
in the bowl of a stand mixer fitted with a paddle attachment on medium-high
speed until light in color and fluffy, about 3 minutes.
2.
Reduce speed to
low, add powdered sugar, and mix until completely incorporated.
3.
Turn off mixer
and add cooled caramel (the bowl without the salt added.)
4.
Beat frosting on
low to combine, then increase to medium-high and beat until airy and thoroughly
mixed, about 2 minutes.
5.
Refrigerate if
not using immediately (or to harden the frosting a bit to make it easier to
spread).
Cake Assembly:
·
Place cooling
rack inside a rimmed baking sheet.
·
Carefully run
knife around cake pan edges to release cakes. Invert 1 cake layer onto
cardboard round. Peel off parchment paper. Place cake layer on round on prepared
rack.
·
Spread a layer of
salted caramel, then a layer of chilled ganache, then a layer of salted caramel
buttercream onto one of the cake layers.
·
Invert second
layer of cake onto another cardboard round. Peel off parchment paper. Carefully
slide cake off round and onto the frosted cake layer on rack.
·
Pour half of
barely lukewarm ganache over cake, spreading over sides to cover. Freeze until
ganache sets, about 30 minutes. Pour remaining ganache over cake, allowing to
drip down sides and spreading over sides if needed for even coverage and to
smooth edges. Freeze to set ganache, about 30 minutes.
·
Fill pastry bag
with remaining salted caramel buttercream. Decorate top of cake.
