A dense, gently sweet Icelandic rye loaf leavened with baking powder and baking soda, mixed with buttermilk, honey and molasses, then baked under a lid in a Pullman pan.
Flatbrauð · flatkaka · flatkökur
Thin Icelandic flatbreads made from rye and whole-wheat flour with boiling water, shaped into rounds, docked and cooked on a hot stovetop or gas grill.

This version follows the 2012 household recipe published by Albert Eiríksson as flatbrauð/flatkökur. It combines rye and whole-wheat flour with salt, sugar and oil, then uses boiling water to make the dough. The writer says he called his mother for baking advice and recalls an aunt describing boiling water as a traditional technique. That family recollection is not a dated origin record, and this measured formula should not stand in for every Icelandic flatbrauð.
The recipe uses 300 g rye flour and 200 g whole-wheat flour. It also calls for extra wheat flour during kneading but gives no amount. The source specifies 300–350 ml boiling water; the ingredient list below preserves that range rather than choosing a precise point within it. It does not state how many rounds the batch makes.
Stir the flours, salt, sugar and oil together before pouring the boiling water over them. The writer lets the mixture cool a little, then kneads in wheat flour and rolls it thin. A plate serves as a cutting guide; a fork docks each round. The source gives no rest, proof, exact thickness, calibrated cooking temperature or time, so those details are left open.
Cook the rounds on a very hot stovetop surface or gas grill. Albert Eiríksson directs cooks to dip each round in cold water immediately after cooking to stop it scorching. His post warns that cooking makes substantial smoke and advises opening windows because smoke alarms may sound. Use ventilation and take care around the boiling water and hot cooking surface.
Flour can carry harmful bacteria. Do not taste the uncooked dough, and wash hands and utensils after mixing. The source gives no validated internal doneness measure; this page does not add one.
Flatbrauð is an Icelandic flatbread name used for multiple formulas. Albert Eiríksson's 2012 page gives a measured household recipe and attributes the boiling-water tip to a relative's recollection; that account is not dated historical evidence for all flatbrauð. The atlas separately records a rye-and-water Mývatn version, which is not the formula used here.
Scaling: source batch only
Boiling water is poured into the flour mixture; splashes can burn hands or skin.
Hazard sourceThe author warns that cooking the rounds on a very hot surface produces substantial smoke and may trigger smoke alarms.
Hazard sourceFlour is a raw agricultural product and should not be tasted before cooking.
Hazard sourcePour the boiling water carefully into the bowl and let the mixture cool enough to handle before kneading.
Control sourceVentilate the kitchen while cooking on the hot surface; the source specifically advises opening windows because substantial smoke can set off smoke alarms.
Control sourceDo not taste raw dough; wash hands and utensils after handling flour.
Control sourceBoiling water enters the dough; allow it to cool enough to handle before kneading.
The source warns of substantial smoke during cooking. Ventilate the room and check that smoke alarms remain functional.
Do not taste the raw dough.
