👩‍🍳 How to Make Gnanakathai at Home

Step 1: Prepare the dough.

Combine all-purpose flour, rice flour, baking powder, and salt in a large bowl. In a separate bowl, cream together softened butter and sugar until light and fluffy. Add the egg and vanilla extract and mix well. Gradually add the dry ingredients to the wet ingredients, mixing until a crumbly dough forms.

Step 2: Form the cookies.

Take small portions of the dough and roll them into roughly ½-inch balls. Place the dough balls on a baking sheet lined with parchment paper, leaving some space between each.

Step 3: Bake the cookies.

Preheat oven to 350°F (175°C). Bake for 12-15 minutes, or until the edges are lightly golden brown. Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.

Step 4: Prepare the sugar glaze.

While the cookies are cooling, prepare the sugar glaze. In a saucepan, combine sugar and water. Heat over medium heat, stirring until the sugar dissolves. Bring the mixture to a boil and let it simmer for about 5-7 minutes, or until it slightly thickens and reaches a syrupy consistency. You can check the consistency by dipping a spoon into the syrup; it should coat the back of the spoon. Remove from heat.

Step 5: Dip the cookies.

Once the cookies are completely cool and the sugar glaze is still warm (but not boiling hot), dip each cookie into the glaze, ensuring it is fully coated.

Step 6: Allow to set.

Place the dipped cookies back on the wire rack to allow the excess glaze to drip off and the sugar coating to set and harden. This might take a few hours.

Enjoy your homemade Sri Lankan Gnanakathai!
