Preheat your oven to 300°F (150°C).
In a large mixing bowl, combine the almond flour with the sunflower seeds, pumpkin seeds, flaxseed, sesame seeds, and salt.
Gradually add hot water and butter and mix with your hands to create a dough.
Place the dough in between two large pieces of baking paper and roll it out with a rolling pin or a tall glass.
Transfer it to the prepared pan keeping the bottom piece of baking paper to make sure it won’t stick to the pan.
Bake in the preheated oven for 40 minutes, until golden brown.
Turn off the heat and allow them to cool down while still in the oven with the door open.
Crack into large pieces and enjoy at room temperature.
