Tonik is a French filled wafer cookie with cocoa and vanilla cream. The original contains palm oil and artificial vanillin - we'll replace palm oil with grass-fed butter for better flavor and nutrition, and use real vanilla extract instead of artificial vanillin. This DIY version eliminates processed oils while delivering the same sweet, crispy wafer experience.

Why This Recipe is Seed Oil Free
Commercial Tonik from tonik often contains inflammatory seed oils like canola, soybean, or sunflower oil. This homemade version replaces them with healthier fats like butter, ghee, coconut oil, or avocado oil — giving you the same great taste without the processed oils.
Ingredients
Organic wheat flour
400g (about 3.25 cups) · Bob's Red Mill Organic Unbleached White Flour
Forms the crispy wafer structure and provides the base carbohydrate content
Replaces soy lecithin as natural emulsifier to bind filling ingredients
Baking soda
2g (about 0.5 teaspoon) · Arm & Hammer Pure Baking Soda
Leavening agent to create light, crispy wafer texture
Sea salt
2g (about 0.25 teaspoon) · Redmond Real Salt
Enhances flavors and balances sweetness in both wafer and filling
Instructions
Step 1. Prepare the wafer dough: In a large mixing bowl, cream 80g softened butter with 100g coconut sugar using an electric mixer for 3-4 minutes until light and fluffy. This creaming process is crucial for creating the right wafer texture - under-mixed dough will result in dense, tough wafers.
Step 2. Mix dry ingredients: In a separate bowl, whisk together 400g wheat flour, 2g baking soda, and 1g salt. Sift this mixture twice to ensure even distribution and prevent lumps that could create tough spots in the wafers.
Step 3. Form wafer dough: Gradually add the flour mixture to the creamed butter, mixing on low speed until just combined - overmixing develops gluten and creates tough wafers. The dough should be crumbly but hold together when pressed. If too dry, add 1-2 tablespoons milk; if too wet, add flour 1 tablespoon at a time.
Step 4. Prepare cocoa-vanilla filling: Melt remaining 40g butter and mix with 100g coconut sugar, 80g cocoa powder, 40g powdered milk, 3g sunflower lecithin, 15ml vanilla extract, and 1g salt. Whisk vigorously for 2-3 minutes until smooth and glossy - the lecithin helps emulsify and prevents separation. The filling should be spreadable but not runny.
Step 5. Shape and bake wafers: Divide wafer dough into 70 equal pieces (about 6g each). Roll each piece into a thin rectangle approximately 4x2 inches and 2mm thick between parchment sheets. Place on lined baking sheets and bake at 350°F (175°C) for 8-10 minutes until edges are lightly golden but centers are still pale. Cool completely on racks - they'll crisp as they cool.
Step 6. Assemble filled wafers: Once wafers are completely cool, spread 1 teaspoon (about 3g) of cocoa filling on the bottom side of one wafer. Gently press a second wafer on top, being careful not to squeeze filling out the sides. Repeat until all wafers are paired. Let assembled cookies rest for 30 minutes to allow filling to set before packaging.
Storage
Store in airtight container at room temperature for up to 1 week. Layer between parchment paper to prevent sticking. Do not refrigerate as this will soften wafers. For longer storage, freeze assembled cookies for up to 3 months.

Savings66%
Higher upfront investment due to organic ingredients, but significant long-term savings. Bulk ingredients like lecithin last for months of baking.
