First Step: Preheat and Prepare: Set your conventional oven to 160°C (320°F) or lower by 20°C if using a convection oven. Line a baking sheet with parchment paper. This preparation ensures your peas biscuits bake evenly and prevents sticking.

Second Step: Combine Dry Ingredients: In a large mixing bowl, sift or whisk together 100 grams of green pea flour, 150 grams of all-purpose flour, 70 grams of icing sugar, 1/4 teaspoon of salt, and 1 teaspoon of baking powder. This blends the components evenly and ensures the baking powder is distributed uniformly, crucial for the right rise and texture.

Third Step: Incorporate the Oil: Gradually pour 80 milliliters of neutral oil into the dry mixture. Start kneading gently until the dough forms a smooth, moist, but non-sticky ball. Add the oil teaspoon by teaspoon if the dough feels dry. Using neutral oil instead of butter keeps the biscuits light and is a great alternative for those with nut allergies or dairy intolerance.

Fourth Step: Shape the Dough: Divide the dough into approximately 15-gram portions (about 1 tablespoon each). Roll each into a smooth ball. Use a small round tool, like a straw or piping nozzle, to imprint coin-like patterns on the top of each piece. This design symbolizes wealth and prosperity, lending authentic cultural value perfect for festive occasions such as Chinese New Year.

Fifth Step: Arrange on Baking Sheet: Place the biscuits about 6 mm (1/4 inch) apart on the parchment-lined baking sheet. They do not spread much during baking, so close spacing is unnecessary. This spacing keeps the biscuits crisp on all sides and preserves their shape.

Sixth Step: Apply Optional Egg Wash: If desired, lightly brush the top of each biscuit with beaten egg yolk to promote a golden brown finish during baking. For a vegan-friendly version, skip this step completely without affecting the final texture.

Seventh Step: Bake: Place the baking sheet in the center oven rack. Bake for 15-20 minutes or until the bottoms turn lightly golden. This baking time ensures the exterior is crisp while the inside remains soft and tender.

Final Step: Cool and Store: Remove the biscuits and allow them to cool on the baking sheet for 5 minutes before transferring them onto a wire rack. Proper cooling maintains the ideal melt-in-your-mouth texture. Store cooled peas biscuits in an airtight container at room temperature; they keep well for several weeks, making them perfect for snacking or gifting.
