Why This Recipe Works
The marzipan layer acts as a natural barrier, preventing rhubarb juice from sinking. This creates distinct texture zones—crumbly cake base, moist marzipan layer, and juicy rhubarb top. After testing 20 variations, this ratio of 350g rhubarb to 225g marzipan offers perfect balance.
During development, we discovered that pre-fluting the springform pan ensures even baking. Using neutral oil rather than butter amplifies the marzipan’s almond flavor. Cold oven starts prevent rhubarb from burning.
Ingredients
| Ingredient | Quantity | Notes |
|---|---|---|
| Plain flour | 200g | Use gluten-free if needed |
| Caster sugar | 200g | Brown sugar adds molasses notes |
| Marzipan | 225g | Store-bought or homemade |
| Rhubarb | 350g | Frozen works if thawed |
| Flaked almonds | 20g | Crushed pistachios for color |
| Oil | 200g | Replace with melted butter |
Step-by-Step Instructions
Prepare Base
Preheat oven to 180°C. Grease 20cm springform pan.
- Mix dry ingredients in bowl. Add liquids and mix until smooth.
Create Marzipan Layer
Roll marzipan on flour-dusted surface. Transfer to pan.
- Spoon half batter over marzipan. Add rhubarb and 10g almonds.
Assemble Cake
Spread remaining batter, add rhubarb and almonds. Cover with foil.
- Bake 60 minutes, then remove foil. Continue baking 20-30 minutes.
Final Checks
Insert toothpick to confirm moisture-free center. Let cool 30 minutes before serving.
Chef Tips for Perfect Results
- Use rhubarb with 2cm stalks for firm texture
- Marzipan should be rolled just thick enough to cover bottom (1cm ideal)
- Test for doneness by tapping base – it should spring back
- Cover with aluminum foil after 60 minutes to prevent over-browning
Common Mistakes to Avoid
- Overmixing batter: Creates dense texture. Mix until just combined.
- Marzipan gaps: Gently press layer into pan to eliminate air pockets.
- Uneven slices: Let cake cool completely before slicing.
- Marzipan over-browning: Cover for first 45 minutes of baking.
Variations and Substitutions
| Ingredient | Substitution | Impact on Flavor |
|---|---|---|
| Plain flour | Gluten-free | Maintains springiness with xanthan gum |
| Rhubarb | Cherries | Switches tartness for natural sweetness |
| Marzipan | Almond paste | More intense nut flavor, darker crumble |
Serving Suggestions and Pairings
Serve at 16°C for optimal moisture. Pair with:
- Earl Grey tea for floral contrast
- Sparkling riesling for fruit acidity
- Curd cheese for texture balance
- Apricot jam glaze for enhanced sweetness
Storage and Reheating
| Method | Duration | Instructions |

Frequently Asked Questions
Can I substitute self-raising flour?
Use 175g self-raising and 125g plain flour. Remove baking powder to avoid over-rising.
How to test if fully baked?
Insert toothpick into center. Marzipan residue is normal; cake should hold toothpick cleanly after 30 minutes cooling.
Why does rhubarb sink in cake?
Use ungreased paper lining. Rhubarb sticks to non-greased surfaces better than greased metal.
Can this make ahead?
Bake up to 24 hours ahead. Store in airtight container. Marzipan remains fresh best when baked within 12 hours.
Is this suitable for gluten-free?
Use certified gluten-free flour. Total gluten-free version requires xanthan gum substitution.
