The no-bake truffle principle
- Temperature control:The only step requiring heat is melting chocolate for coating. Chocolate melts at 45–50°C and must be cooled to 35–38°C before spirulina-containing truffles are dipped into it. At 35°C, the chocolate coats and sets; phycocyanin in the truffle centre remains below 35°C due to the brief contact time. For absolute certainty: use a thermometer to verify chocolate temperature before coating.
- Dose control:Each truffle contains a precisely measured amount of spirulina (0.5–1 g per truffle typically). A batch of 12 truffles with 6 g spirulina total = 0.5 g per truffle. Two truffles = 1 g; six truffles = 3 g daily dose. This format is ideal for people who prefer to snack their daily dose rather than drink it.
Recipe 1: Dark chocolate spirulina date truffles
Makes 12–15 truffles (0.4–0.5 g spirulina per truffle). The date sweetness and chocolate bitterness completely mask spirulina.
- 200 g Medjool dates, pitted
- 100 g almonds, processed to a coarse meal
- 2 tbsp cacao powder
- 5 g spirulina powder
- 1 tsp vanilla extract
- Pinch of sea salt
Coating:
- 100 g dark chocolate (70%+), melted and cooled to 35–38°C
Process dates until they form a paste. Add almonds, cacao, spirulina, vanilla, and salt — process until the mixture holds together when pressed. Roll into balls (approximately 20 g each). Refrigerate for 30 minutes to firm. Melt chocolate; cool to 35–38°C (use thermometer). Dip each truffle, place on baking paper, allow to set at room temperature or briefly in fridge.
Recipe 2: Coconut spirulina lime truffles
Makes 12 truffles. No chocolate coating — rolled in desiccated coconut. The lime cuts through spirulina’s earthy flavour; coconut provides the binding fat.
- 100 g cashews, raw
- 60 g desiccated coconut + extra for rolling
- 3 tbsp coconut oil, melted and cooled to room temperature
- 2 tbsp maple syrup
- Zest and juice of 1 lime
- 5 g spirulina powder
Process cashews to a fine meal. Add all other ingredients and process until the mixture comes together (it will be soft). Refrigerate for 20 minutes until firmer. Roll into balls and coat in desiccated coconut. Return to fridge; set in 30 minutes. Store refrigerated — the coconut oil softens at room temperature above 24°C. The lime acid produces the same brightening effect on spirulina colour as in shots: a vivid electric teal-green visible through the coconut coating when cut open.
Recipe 3: Matcha spirulina energy truffles
Makes 15 truffles. Double green format; high protein from almond butter.
- 150 g Medjool dates, pitted
- 80 g almond butter
- 40 g rolled oats, processed briefly
- 4 g spirulina
- 1 tsp matcha powder
- 1 tbsp hemp seeds
- 1 tsp vanilla
Process dates, then add almond butter, oats, spirulina, matcha, hemp seeds, and vanilla. The mixture will be dense. Roll into balls; coat in sesame seeds or hemp seeds instead of chocolate. No heat involved at any stage. These truffles are more substantial — closer to energy ball format — and work well as a pre-workout snack.
Recipe 4: Pistachio spirulina raw truffles
Makes 12 truffles. The natural green of pistachio combines with spirulina for an intensely green centre visible on cross-section.
- 100 g raw pistachios, shelled
- 80 g cashews
- 3 tbsp agave or maple syrup
- 2 tbsp coconut oil
- 5 g spirulina
- Zest of 1 lemon
- Pinch of cardamom
Process pistachios and cashews to a meal. Add remaining ingredients and process until combined. Roll into balls; coat in crushed pistachios. Cardamom provides a Middle Eastern flavour note that works exceptionally well with spirulina’s mineral character.
Recipe 5: Protein spirulina truffles (post-workout)
Makes 12 truffles. Higher protein content from pea protein powder and hemp seeds alongside spirulina.
- 100 g pea protein powder (unflavoured or vanilla)
- 100 g nut butter (peanut or almond)
- 3 tbsp maple syrup
- 2 tbsp water (add gradually)
- 5 g spirulina powder
- 2 tbsp hemp seeds
- 1 tsp vanilla
Mix pea protein, nut butter, maple syrup, spirulina, hemp seeds, and vanilla by hand. Add water gradually until the mixture holds a ball shape (the pea protein absorbs moisture slowly). Roll into balls and coat in hemp seeds or cacao powder. Each truffle contains approximately 7–8 g protein from combined pea protein, nut butter, spirulina, and hemp. A 2-truffle post-workout serving provides 14–16 g protein in bite-sized format.
Storage and phycocyanin stability
- Room temperature storage: 2–3 days (coconut oil truffles may soften above 24°C; others are more stable)
- Refrigerator: 7–10 days; phycocyanin remains stable at 4°C for this duration
- Freezer: up to 3 months; phycocyanin is stable at –18°C; defrost at room temperature before eating
