Nutty-vanilla filling with toasted pecans and coconut, enriched by a slowed thickened egg-butter blend. Substitutes almonds for pecans. Uses evaporated milk instead of condensed, lighter but still creamy. Vanilla swapped with almond extract for unexpected warmth. Cooks just shy of curdling, watching texture and aroma, then folds in toasted nuts and coconut. Rolled into cakes or logs, cocoa dusted or layered with white chocolate glaze or berry jam. Layers of texture and mellow caramel sweetness balance the nutty crunch. A familiar base bumped with personal twists and tips for handling custard staging, nut toasting cautions, and decorating flourishes.

#kitchen tips
A German chocolate filling that’s anything but boring. I swapped pecans for almonds for firmer bite and a sweeter undertone. Coconut still the star, toasted just right so you get crunch but none of that dry powdery feel. Instead of thick canned milk, I went for evaporated milk — cuts some sugar, keeps silky. Egg yolks cook slowly with softened butter in a pot; no shortcuts or rushing. This custard is about patience, watch the texture change, use your finger swipe test. Add almond extract in place of vanilla for an unexpected flare, think marzipan whispering beneath. Forget overcooking or scrambling eggs — I’ve been burned. This is a tactile, aromatic dance at the stove with nutty scents rising and creamy thickening. I love rolling it into chocolate sponge or even a dense pound cake. Dust with cocoa for rustic finish or drizzle melted white chocolate and layer tart berry jam—a bold companion to the mellow custard. It’s kitchen science and flavor boldness in one.
Ingredients
- 130 ml chopped almonds
- 200 ml shredded unsweetened coconut
- 200 ml evaporated milk
- 3 egg yolks
- 70 ml softened unsalted butter
- 5 ml almond extract
- 2 tbsp unsweetened cocoa powder
About the ingredients
Almonds add a firmer crunch and subtle sweetness compared to pecans’ buttery softness. You can use walnuts but soak them briefly if bitter. Unsweetened shredded coconut is mandatory; sweetened will throw off sugar balance and moisture. Replace evaporated milk with regular milk plus a dollop of cream for richness, but custard will be thinner. Butter must be softened, not melted; helps smooth blending and prevents curdling when heating eggs. Almond extract is a twist, offers nutty aroma, but you can replace it with vanilla or even rum extract for boozy depth. Cocoa powder is for dusting or mixing into the garnish, not the filling itself — keeps filling smoother. Toast nuts and coconut separately if you want distinct crunches, but mixing in one pan saves time. Watch closely during toasting; burnt nuts taste acrid and ruin the delicate custard balance.
Method
- Start by toasting almonds with coconut in a dry skillet over medium heat. Listen for the first pop, smell nutty sweetness rising. Stir constantly to avoid dark spots. Should take about 4-5 minutes until gold-brown edges appear. Cool on a plate immediately or coconut will steam and clump.
- Next, whisk yolks loosely. Combine evaporated milk, butter, and egg yolks in a heavy-bottomed pot. Cook over low heat, stirring constantly. Key is gentle heat — no rushing. Custard thickens when it coats the back of a wooden spoon and leaves a line after a finger swipe.
- Watch closely, 6-7 minutes usually enough. Too hot or fast heating scrambles the eggs — signs are lumps or stringy texture. If that happens, remove from heat immediately, whisk vigorously to recover if slight, otherwise start over. No tall orders if you’re patient and attentive.
- When thickened, off heat. Stir in toasted almonds, coconut, and almond extract. Mix until combined. Let cool to room temperature uncovered. A crust can form — stir gently to reincorporate before using.
- Use as filling for rolled cakes or as spread inside layered sponge cake. For finishing, dust with cocoa. Alternative: a layer of raspberry jam beneath filling for tart contrast, then drizzle with melted white chocolate instead of plain cocoa.
- Store in fridge covered, bring to room temp before assembling to soften butter and blend flavors.
- Pro tip: For flavor depth, dry roast coconut separately a tad longer, near toasted brown but not burnt; adds smoky note. To save time, use pre-toasted almonds but not coconut — home toasting is crucial for balance.
- Common mistake? Overcooking custard. Heat simmer, never boil. Keep stirring. Use heavy saucepan to distribute heat evenly and prevent hotspots.
Cooking tips
Toasting nuts and coconut kicks everything off—don’t walk away. Constant stirring and close eye essential to avoid bitter char. When roasting slows or nuts start popping slightly, aroma will change; that moment is your signal. For custard, hold heat low and steady. Egg yolks plus butter plus evaporated milk is a delicate mix; too hot and you get scrambled strings, too cool and it won’t thicken. Use wooden spoon, scrape the sides and bottom often or risk thin spots burning. The custard thickens when it coats the spoon back like a veil. The ‘finger swipe’ test is foolproof—run finger through the custard on the spoon; if it leaves a clear line, thick enough. Add nuts, coconut, and almond extract off heat, folding gently to keep texture intact. Cooling without covering prevents condensation from making the mixture watery. Before using, stir gently to reincorporate any skin or crust. Assemble while fillings are soft but not runny. For decorating, cocoa dusting gives a rustic finish but for more elegance, warm some white chocolate and drizzle on top. Add a smear of tart jam under filling for contrast—a trick I found amps the whole experience.
Chef's notes
- 💡 Toast almonds and coconut separately. Use medium heat, stir constantly to prevent bitter spots. Listen for first pops, smell nutty aroma—signals near done. Cool nuts right away to stop cooking steam. Don’t rush. Dry coconut longer for smoky touch but watch closely, burns quick.
- 💡 Cook custard slow. Blend egg yolks, butter, evaporated milk in heavy pan. Heat low, stir all time. Heat gently then you see custard coat wooden spoon like a veil. Finger swipe test key—line clear means thick enough. Stop heat immediately before curdling. Patience needed here, can save batch.
- 💡 If custard lumps or strings form, off heat whisk fast to smooth if early stage. Sometimes must restart to avoid scrambled eggs flavor. Butter must be softened not melted. Melted butter risks curdle. Add almond extract off heat for aroma without cook-off. Vanilla or rum extracts swap but flavor shifts.
- 💡 Filling too runny? Refrigerate longer, butter firms up and thickens. Too thick? Warm gently, fold small milk splash. Toast nuts quicker? Oven 350°F five min, watch. Don’t mix nuts and coconut if want distinct crunch. Coconut burns faster, remove once lightly golden. Clumping means moisture—keep dry always.
- 💡 Cool custard uncovered to avoid watery condensation. If crust forms, stir gently to reincorporate before use. Dust with cocoa powder or drizzle melted white chocolate for texture contrast. Add tart jam layer underneath filling for punch. Store in fridge covered but bring to room temp before assembling to soften butter flavors.
Common questions
How to tell custard is thick enough?
Look for coating on wooden spoon like veil. Finger swipe test—run finger through custard line stays clean. Too hot scrambles eggs, watch closely 6-7 min usual. Slow is key.
Can I swap almonds with other nuts?
Walnuts work but soak briefly if bitter. Pecans softer, shifts texture. Toast separately for best crunch. Avoid sweetened coconut, makes filling too wet sweet. Different nuts change nutty notes but cook same way.
What if nuts or coconut burn?
Toss batch—bitterness stays. Toast coconut lighter than nuts. Remove when golden, not brown. Clumping means moisture, dry nuts before toasting. Burnt nuts ruin custard balance no fix.
How to store filling properly?
Store covered in fridge. Eat within few days. Let sit room temp before use; softens butter blend smooth. Can freeze but texture might change slightly. Always stir gently if crust forms before assembling.
