In one bowl sift together the flour, baking powder and salt.
In the mixer, beat together the sugar, honey, eggs, butter, lemon zest and juice and vanilla extract.
Bit by bit, add in the dry mixture of ingredients into the wet mixture.
Once all combined, shape into squares.
Bake for 25 minutes, then remove and cool.
Place back into the oven and bake for another 10 minutes each side.
Remove from oven, transfer and cool.
Why does this dough require a second trip to the oven? Twice-baking serves to drive out residual moisture, transforming a tender, cake-like interior into a dry, shelf-stable biscuit with an extended storage window of up to two weeks in an airtight container. Understanding the physical mechanics of this process ensures structural integrity regardless of batch size.
Scaling Ratios and Structural Integrity
Adjusting yields requires more than simply multiplying figures. Flour and butter ratios must remain strictly proportional to maintain structural stability, whereas leavening agents like baking powder demand caution when scaling upward; doubling chemical leaveners can create a metallic off-flavor and an overly porous crumb that collapses during the second dehydration phase. Room temperature eggs emulsify fats more efficiently than cold ones, preventing the batter from breaking during the initial mixer stage.
Common Pitfalls in the Double-Bake Process
Scorching remains the primary hazard during the secondary ten-minute per-side browning phase. Sugars and honey caramelize rapidly at 350 degrees Fahrenheit, meaning oven hot spots can easily burn the exterior before the center finishes drying. Watch for a deep golden hue and a firm surface texture as visual indicators of doneness, removing the pieces immediately if edges darken prematurely.
