An Esterházy cake is a Hungarian cake that was one of the most famous cakes in the Austrian-Hungarian empire.
SPONGE CAKE (1)
INGREDIENTS
- 110 g sponge crumbs
- 100 g hazelnut powder
- 45 g cake flour
- 150 g egg whites
- 120 g sugar
- 25 g butter
DIRECTIONS
- Preheat oven to ~340 F and prepare a baking pan with a Silpat mat
- Sift dry ingredients into a bowl
- Combine the egg whites and sugar to create a medium peak meringue, ideally in a copper bowl
- Add the dry ingredients into the meringue all at once and fold together gently
- When the mixture is almost combined, add in butter and fold it in
- Pipe lines onto a Silpat mat – spreading the batter with a spatula would deflate the batter too much
- Bake until golden brown and dust with icing sugar
Notes:
- Well aged egg whites (2 – 3 weeks) are better since the proteins are relaxed
- If egg whites are fresh, then salt can untangle the albumin to get a similar effect
- They should be at least room temperature
- You need to establish volume in the meringue BEFORE you add the sugar. Sugar is a heavy stabilizer, so the volume should be established first. Once you have the volume and the egg white is somewhat stiff, gradually start adding the sugar and whip until a medium peak is formed

SPONGE CAKE (2)
INGREDIENTS
- 120 g soft butter
- 40 g granulated sugar
- orange zest
- 5 egg yolks
- 150 g egg whites
- 70 g granulated sugar
- 95 g cake flour
DIRECTIONS
- Preheat oven to 350 F and line a baking sheet with a silpat mat
- Cream together the soft butter and sugar until white and fluffy; add orange zest
- Once light and fluffy, add the egg yolks one at a time and mix until incorporated
- In a copper bowl, mix the egg whites and granulated sugar until they form a medium peak meringue
- Add 1/3 of meringue into butter mixture and combine. Note that this will be streaky.
- Add the rest of meringue to butter mixture and combine (don’t overwork it)
- Fold in the sifted flour
- Gently spread the batter onto a silpat to at least the length of the first sponge, and level the whole thing out
- Bake until the cake is a light golden brown
Notes:
- When the meringue first gets added to the butter mixture, it will never be fully incorporated because of the proportion of egg:butter. It will deflate if you overwork it, so it’s fine for it to be streaky looking
- This sponge can break quite easily

BUTTERCREAM
INGREDIENTS
- 150 g soft butter
- 30 g granulated sugar
- 1 egg yolk
- 1 egg
- 30 g granulated sugar
- 60 g dark chocolate
- 60 g praline paste
DIRECTIONS
- Set the chocolate on a bain marie to melt, being careful not to overheat it
- Cream together the butter and sugar until white and creamy
- Mix the chocolate into the creamed butter and mix well
- Add the praline paste and mix
- Whisk the eggs and sugar (sabayon) over a bain marie until you get a “little ouch”
- Put the sabayon into a stand mixer and whisk vigorously until it reaches ribbon stage
- When the sabayon is done, mix it well into the butter mixture
ASSEMBLY
- Prepare a syrup and jam of choice for layering
- Flip sponge 1 onto a cutting board, and trim edges
- Cut it exactly in half to make 2 matching pieces
- Cut sponge 2 into 2 matching pieces
- Layer as follows: sponge 1, buttercream, sponge 2, soak in syrup, jam, sponge 1, buttercream, sponge 2, soak in syrup, jam
- Temper fondant to pour over top (should be a “little ouch” or 50 – 60 C)
- Some lemon juice can cut the sweetness
- Can be thinned with some water as needed
- Brush on the fondant, pipe thin lines of chocolate, and then swipe with toothpick or skewer to create design
- All must be done quickly (within ~20 seconds) before fondant sets
