Use cassava flour rather than tapioca starch; they absorb water differently and do not produce the same dough.

Gluten-Free Coconut Cassava Shortbread Recipe
Follow the tray sizes, portions and baking intervals in the instructions below.
Total time includes hands-on preparation, required chilling or resting, whole-batch cooking, cooling and finishing.
Kitchen tools you’ll need
- mixing bowl
- mixer
- kitchen scale
- two 13 x 18-inch half sheets
- parchment
- fork
- wide spatula
- cooling rack
Ingredients
US measures are approximate. Gram weights help keep portions consistent; spice weights vary with density.
Instructions
Mix and hydrate
- Mix and hydrate: Stir butter and sugar smooth; add flour blend, cassava flour, almond meal, coconut and salt. Press just until clumps hold, cover and rest 20 minutes at room temperature before shaping. Check all ingredients and preparation surfaces for gluten cross-contact; cassava flour is not tapioca starch.
Shape and chill
- Shape and chill: After the 20-minute hydration rest, divide dough into 24 equal portions, about 15 g each. Press into 1 3/4-inch rounds about 1/3 inch thick and dock lightly with a fork. Refrigerate 30 minutes until firm. Hydration plus chilling totals 50 minutes.
Bake the whole batch
- Bake the whole batch: Heat oven to 325°F (165°C) conventional or 300°F (150°C) fan. Use two parchment-lined 13 x 18-inch half sheets, 12 cookies per sheet, spaced at least 1 inch apart. Bake one tray at a time on the middle rack for 20–24 minutes, turning front to back halfway; keep the waiting tray refrigerated. Edges and bases should be pale gold and the centers dry. Whole-batch oven time is 48 minutes for both trays.
Cool the cookies
- Cool the cookies: Rest 10 minutes on each tray, then cool 20 minutes on a rack before packing; the 30-minute cooling allowance includes the tray rest.
Timing and scaling
- Timing and scaling: 25 min hands-on + 50 min required chill/rest + 48 min whole-batch oven baking + 30 min cooling/setting = 153 min. Cooling includes tray/pan rests and runs from the final tray; earlier-tray cooling may overlap later baking. Ingredient warm-up and frozen-dough thawing are extra; preheat during shaping/chilling. Scale ingredients and US equivalents, not oven temperature, piece sizes or per-tray bake time; extra trays extend the whole-batch time.
Chef’s Science & Pro Tips
Ingredient science
Cassava replaces part of the binder-containing gluten-free blend, while almond meal supplies fat to balance the coconut shreds and low-gluten structure.
Technique & texture
Use cassava flour rather than tapioca starch; they absorb water differently and do not produce the same dough.
Finishing & serving
Wait through the full cooling period before lifting stacks; the nut-and-cassava crumb is fragile while warm.
Storage and make-ahead
| Method | How long | What to do |
|---|---|---|
| Room temperature | 5 days | Up to 5 days. Seal fully cooled cookies airtight in a cool dry room. Separate layers with parchment; keep away from moist treats. |
| Refrigeration | up to 7 days | Unnecessary; up to 7 days if needed. Baked refrigeration is unnecessary for this formula; use only if the room is warm. Seal airtight to prevent condensation and odors. |
| Raw freezing | 1 month | Up to 1 month. Freeze the unfilled dough tightly wrapped. Thaw overnight in the refrigerator, then shape and complete the stated chill. Thawing time is additional. |
| Baked freezing | 2 months | Up to 2 months. Freeze completely cooled cookies airtight with parchment between layers. Thaw sealed at room temperature for 1–2 hours. |
| Restoring | As described | Optional 3–5 minutes. Refresh plain cookies at 300°F (150°C) conventional or 275°F (135°C) fan for 3–5 minutes, then cool 20 minutes before sealing. This extra time is outside fresh-batch timings. |
Notes
- Scale ingredients, including US measures, without changing cookie size or oven temperature. Extra trays increase whole-batch time.
