The flour and butter are your foundation. King Arthur or Gold Medal flour gives the best lift, and European-style butter (like PlugrĆ” or President) has more fat for that tender crumb. If you can't find it, Land O'Lakes European-style works too. The rum? Bacardi 151 or Gosling's Black Seal add depthāskip the cheap stuff. For the chocolate glaze, Valrhona or Callebaut 70% bars melt perfectly, but Ghirardelli squares
No dark rum? Spiced rum or even bourbon will work, but reduce to 1/3 cupāit's stronger. Can't find vanilla bean paste? Double the extract and add a pinch of ground vanilla bean (if you have one). The custard needs to be silky, so whisk constantly while heating. If your custard curdles, strain it immediatelyāit'll still taste great. For the sponge, don't overmix the egg whites. They should be glossy but not dry. And if you're nervous about the 'space' layers, use parchment paper between each layerāit prevents sticking without sogginess. Assembled cake keeps 3 days in the fridge, covered tightly. For longer storage, freeze the fully assembled cake (unfrosted) for up to 2 months. Let it thaw overnight in the fridge before glazing. The glaze sets at room temperature in about 1 hourToasted cake slices with whipped cream are my favorite breakfast. And if you make extra custard? Pour it into ramekins and bake for 20 minutes at 350Ā°Fāyou've got instant crĆØme brĆ»lĆ©e.

Step-by-step instructions for Dutch-inspired space cake
Let's build this iconic Dutch cake with its signature caramelized layers and velvety texture.
šØāš³ Step 1: Prepare the Caramelized Rum Layer
In a heavy-bottomed saucepan, combine the 1 cup unsalted butter, 1.5 cups granulated sugar, and 0.5 cup rum over medium-low heat. Stir gently until the sugar dissolves completely and the mixture turns a deep amber colorāthis should take about 10-12 minutes. You'll smell that rich, boozy caramel aroma developing.
Remove from heat and immediately stir in 1 tbsp vanilla extract and 2 tsp vanilla bean paste. Let the mixture cool slightly to 110Ā°F before usingāit should be thick but still pourable. If it cools too much, gently reheat until it reaches the right consistency. This layer is the cake's signature flavor foundation, so don't rush the caramelization.
š³ Step 2: Make the Vanilla Custard Filling
In a separate bowl, whisk together 6 whole large eggs, 1 cup milk, 2 tbsp cornstarch, and 0.5 tsp salt until smooth. Slowly pour in the 2 cups heavy cream while whisking continuously. Pour this custard mixture through a fine-mesh sieve into a clean saucepan to remove any lumps.
Cook over medium heat, stirring constantly with a wooden spoon, until the custard thickens enough to coat the back of the spoonāabout 5-7 minutes. Remove from heat and stir in the 0.25 cup cocoa powder and 1 tbsp vanilla extract. Spread the custard on a parchment-lined baking sheet and refrigerate until completely chilled and firmāthis should take about 2 hours. The cold custard will create those signature layers when baked.
š„ Step 3: Assemble the Cake Layers
Preheat your oven to 350Ā°F. Sift the 2.5 cups all-purpose flour onto a clean surface and mound it into a volcano shape. Make a well in the center and add the chilled custard filling. Gently fold the flour into the custard using a spatula until just combinedādon't overmix. The dough should be thick and slightly sticky.
Divide the dough into three equal portions (about 12 oz each). On a parchment-lined baking sheet, spread each portion into a 9-inch circle, about Ā¼-inch thick. Brush each layer generously with the cooled caramelized rum mixture. Place the chilled custard sheet on top of the first layer, then add the second layer with more caramel, and finally the third layer with the remaining caramel.
š„ Step 4: Bake the Space Cake
Bake the assembled cake in the preheated oven for 45-50 minutes, until the top is golden brown and a toothpick inserted comes out clean. The cake should rise slightly and develop a beautiful caramelized crust. Let it cool completely in the pan before removingāthis prevents crumbling.
Once completely cooled, place the cake on a serving plate and drizzle the remaining caramelized rum mixture over the top. Dust with 1 cup powdered sugar sifted through a fine-mesh sieve for that classic Dutch presentation. The cake should have distinct layers visible through the caramel glazeāthis is what makes it a true space cake!
š½ļø Step 5: Prepare the Chocolate Glaze
In a heatproof bowl set over simmering water, melt the 8 oz dark chocolate and 0.5 cup unsalted butter together, stirring until smooth. Remove from heat and whisk in 1 cup powdered sugar until completely dissolved and the glaze is glossy and thick enough to coat the back of a spoon.
Drizzle the chocolate glaze over the cake in an attractive pattern, letting it drip down the sides slightly. Let the glaze set at room temperature for 30 minutes before slicing. The contrast between the rich chocolate and caramelized rum layers is what makes this cake truly specialāeach bite delivers that perfect balance of sweetness and depth.
Pro Tips For Making Amsterdam Space Cake
- Cream Butter Cold: Take your butter straight from the fridgeāno softening needed. The Amsterdam Space Cake relies on that sharp contrast between cold butter and warm sugar for proper emulsification, and skipping this step means your batter will fight you instead of coming together smoothly.
- Whisk Eggs Alone First: Beat your eggs and sugar separately until pale and thick before combining with the butter mixture. I learned this the hard wayāadding whole eggs to cold butter makes the batter gloppy, and youāll end up with a dense, sad cake instead of that light, airy texture.
- Donāt Overmix the Batter: Stop folding in the flour the second itās just incorporatedāno streaks, no extra stirring. Overmixing develops gluten, and your cake will turn out tough instead of tender. The batter should look like thick, slightly lumpy pudding, not smooth cake batter.
- Bake in Two Rounds: Divide the batter evenly between two 8-inch pans (or one 9-inch if youāre impatient like me). Baking in shallower layers ensures even cooking and prevents the center from staying underdone while the edges burn. Rotate pans halfway through for symmetryāyour future cake layers will thank you.
Creative variations of this recipe
Classic Rum Variations
For a more intense rum flavor, replace the 0.5 cup rum with Ā½ cup dark rum (like Gosling's Black Seal) plus Ā¼ cup aged rum (like Appleton Estate Reserve). The aged rum adds depth without overpowering. Iāve also found that adding 1 tsp cinnamon or Ā½ tsp nutmeg to the caramelized rum layer enhances the Dutch spice profile. š¹
Coffee-Inspired Twist
Swap the vanilla custard for a coffee custard by adding 2 tbsp instant espresso powder to the custard mixture. This creates a mocha-inspired layer that pairs beautifully with the rum caramel. For extra richness, fold 2 oz dark chocolate (melted and cooled) into the custard before assembling. The contrast of coffee and rum is surprisingly sophisticated.
Citrus Zest Layers
Brighten the cake by adding 1 tbsp lemon or orange zest to the caramelized rum layer. The citrus cuts through the richness and adds a refreshing note. For a tropical variation, replace the vanilla extract in the custard with 1 tbsp coconut extractstrong> and add Ā½ tsp grated lime zest. This works especially well with a lighter rum like Malibu.
Boozy Fruit Fillings
Replace the custard with a fruit compote for a lighter texture. Simmer 1 cup mixed berries (raspberries, blackberries, or strawberries)strong> with 2 tbsp apricot jamstrong> and 1 tbsp rumstrong> until thickened. Spread this between the cake layers instead of custard. For a decadent option, use a passion fruit curdstrong>āblend 1 cup passion fruit pulpstrong> with 2 egg yolks, Ā¼ cup sugar, and 1 tbsp rum, then cook until thick.
Gluten-Free Adaptation
For a gluten-free version, replace the 2.5 cups all-purpose flourstrong> with a 1:1 gluten-free flour blend (like Bobās Red Mill 1-to-1). Add Ā½ tsp xanthan gumstrong> to improve texture. The custard and caramel layers remain unchanged, but the sponge will be slightly denser. Brush the layers with extra rum glaze to compensate for the drier texture. š«
Vegan Chocolate Glaze
To make the chocolate glaze vegan, melt 8 oz vegan dark chocolatestrong> (like Enjoy Life brand) with Ā½ cup coconut oilstrong> instead of butter. Replace the powdered sugar with 1 cup coconut sugar**strong> for a caramel-like sweetness. The glaze will still set firm but with a slightly chewier texture. Drizzle over the cake as usual for that glossy finish.

Frequently asked questions
Why does the Amsterdam Space Cake have "spaces" between layers?
The signature "spaces" come from alternating thin cake layers with chilled custard sheets. When baked, the custard melts slightly but doesn't fully absorb, creating those distinctive gaps. This technique also prevents a dense, heavy texture while maximizing flavor contrast between the rum-soaked sponge and creamy custard.
Can I make this cake without rum?
Yes! Replace the 0.5 cup rum with 0.5 cup orange juice or apple cider for a non-alcoholic version. For depth, add 1 tsp vanilla bean paste and Ā½ tsp cinnamon to the caramel layer. The flavor will be sweeter but still rich and aromatic.
How do I prevent soggy layers in my Space Cake?
Keep your custard completely chilled before assembling, and brush each cake layer with only a thin coat of caramelized rum mixture. Use parchment paper between layers to prevent sticking, and bake immediately after assembly. If your kitchen is humid, chill the assembled cake for 30 minutes before baking to help set the layers.
What's the best way to store leftover Space Cake?
Wrap the cake tightly in plastic wrap, then place it in an airtight container. Store at room temperature for up to 2 days, or refrigerate for up to 5 days. For longer storage, freeze the unfrosted cake for 2 months. Thaw overnight in the fridge before adding the chocolate glaze. The texture stays best when kept cool.
Can I make the custard ahead of time?
Prepare the custard up to 3 days in advance and store it in an airtight container in the fridge. When ready to assemble, spread it on parchment paper and freeze solid for 1 hour before using. This ensures clean layers when baking. The flavor actually improves with time as the ingredients meld.
