Russian Honey Cake
Ingredients:
For Burnt Honey:
¾ cup honey
¼ cup water
For cake layers:
¼ cup burnt honey
¾ cup honey
1 cup + 2 Tbsp unsalted butter, cut into ½ inch pieces
6 large eggs (300g w/o shells)
2 ½ tsp baking soda
¾ tsp fine salt
1 tsp cinnamon
3 ¾ cup AP flour
For Frosting:
½ cup burnt honey
1 ¼ cup dulce de leche (or prepped with 1 14 oz can of sweetened condensed milk)
½ tsp fine salt
4 ¾ cup heavy whipping cream, very cold and divided
Directions:
Dulce de Leche (either store bought or prepared in advance):
Peel the label off a can of sweetened condensed milk, and place unopened in a large saucepan. Fill the pot with enough water to cover the can by 1 to 2 inches. Place over high heat and bring to a boil, then immediately reduce heat to med-low or medium, so that the water remains a slow simmer.
Watch the water level every ½ hour to make sure that it’s at least 1 inch above the can. It could explode if not. Add more hot water as necessary to keep the water level high enough. Simmer the can for 3 hours for a lighter color and flavor, and 4 hours for a deeper one.
Turn off the heat, and remove the can from the saucepan. Set aside and allow the can to reach room temperature before opening. Don’t open while hot.
For Baking Sheets:
Adjust oven rack to middle position and preheat oven to 375 degrees.
Line 2 or 3 baking sheets with silicone mats. On a large piece of parchment paper, trace a circle around a 9-inch cake pan and place the paper underneath one of the silicon mats. If you don’t have silicone mats, trace the 9-inch circles directions onto 11 baking-sheet-size pieces of parchment paper. Place a piece of parchment tracing-side down on a baking sheet. Set aside.
For Burnt Honey:
Place ¾ cup of honey in a 2-quart saucepan, and set over high heat. Bring to a simmer, then reduce the heat to medium.
Cook the honey, stirring occasionally with a heat-proof spatula, until the color darkens and turns from pale yellow to dark amber; about 3 minutes.
Turn the heat off and carefully add ¼ cup water. Allow the honey to sputter until it stops bubbling, then whisk to combine. Transfer to a heatproof measuring cup and set aside.
For Cake Layers:
Fill a medium saucepan with 2 inches of water, and bring to a simmer. Combine 1/4 cup burned honey, 3/4 cup honey, sugar and butter in a large heat-proof bowl, and place over the pot of water, making sure the simmering water is not touching the bottom of the bowl.
Crack eggs into a small bowl, and set aside. Stir together baking soda, salt and cinnamon in a separate small bowl.
Gently stir the honey/butter mixture until the butter has melted, then whisk well to combine. Use your finger to test the temperature of the mixture. When it’s warm, add the eggs while whisking. When the mixture returns to the same temperature, add the cinnamon mixture, and continue whisking for another 30 seconds. The batter will begin to foam and emit a curious odor. Remove the bowl from the heat, and allow it to cool until it’s warm.
Place the flour in a fine-mesh sieve, and sift over the batter in three batches, whisking to incorporate the flour completely with each addition, until completely smooth. The batter will spread more easily when it’s warm, so place the bowl in a warm spot, such as atop the preheating oven or over the pan of simmering water (off heat).
Spoon a heaping 1/3 cup of batter over the prepared silicon mat or parchment paper. Use an offset spatula to evenly spread the batter to the edges of the traced circle. Make sure that the entire circle is well covered, otherwise, add a little more batter in patchy areas and smooth out.
If using silicon mats, carefully slide the paper with the traced circle from underneath the silicon mat and place under another one. Repeat spooning and smoothing remaining batter until you’re out of baking sheets. Ultimately, you should end up with 11 layers.
As you continue spreading the remaining batter on the baking sheets, bake as many layers at a time as possible, for 6 to 7 minutes, until the cake turns a deep caramel color, springs back at the touch and a toothpick inserted in the center comes out clean. Do not overbake!
When each layer is done, slide the silicon mat or parchment off the baking sheet to prevent overbaking. If reusing baking sheets while they are still hot, reduce cooking time to 5 to 6 minutes.
When the cake layers are cool enough to handle, examine them. If any spread outside the traced circles as they baked, use a sharp knife or pair of scissors to trim them. Don't throw away the trimmings. Before the cakes cool entirely, pull each one carefully from the silicon mat or parchment, then place back on the parchment or wire rack on a flat surface, and allow to cool completely.
When all the layers are baked, reduce the oven temperature to 120C/250F, and return the least attractive layer (and trimmings) to a baking sheet, and place in the oven to toast until deep reddish brown and dry, about 15 minutes. Allow it to cool, then use a food processor to grind into fine crumbs. Cover and set aside.
For the frosting:
Place 1/2 cup burned honey, dulce de leche and 1/2 teaspoon fine salt into a medium bowl. Whisk by hand until combined, then slowly pour in 3/4 cup cream and mix until homogeneous. Chill until completely cooled, about 30 minutes.
Pour 4 cups heavy cream into the bowl (preferring chilled) of a stand mixer, with the whisk attachment. Whip at medium speed to soft peaks, about 6 minutes, then add honey mixture and whip to medium stiff peaks. If your mixer holds less than 5 quarts, make frosting in 2 batches and then combine in a large bowl, or use a large bowl and a hand mixer.
To Assemble cake:
Assemble the cake on a 10-inch cardboard circle or flat serving plate. Place a cake layer in the center of the cardboard, then spoon a heaping cup of frosting onto the center. Use an offset spatula to spread the frosting evenly, leaving a 1/4-inch ring around the edge. Continue with alternating layers of cake and frosting, ending the last layer with frosting. Use any leftover frosting to smooth out the sides of the cake, but don’t worry if the edges of some cake layers poke through the frosting; they're gonna be covered up anyway. You should use up all the frosting.
Place the frosted cake on a rimmed baking sheet and use your hands to press the sides with the reserved toasted cake crumbs. You could cover the top too if you prefer.
Chill the cake in the fridge overnight to give the frosting time to meld into the cake layers and soften them. Slice into thin wedges and serve cold or at cool room temperature. Cake can be made up to two days in advance. Refrigerate leftovers for up to 3 days.
