Prep the pan and oven: Preheat your oven to 350°F (175°C). Line a 8.5 x 4.5-inch loaf pan with parchment, leaving overhang for easy lifting. Lightly grease the sides.

Mix dry ingredients: In a large bowl, whisk 1 1/2 cups golden flaxseed meal, 1 cup almond flour, 1 tablespoon baking powder, and 1 teaspoon salt. Break up any lumps so the mixture is even.

Whisk the wet ingredients: In a separate bowl, beat 5 large eggs until slightly frothy. Stir in 2 tablespoons olive oil, 1 tablespoon apple cider vinegar, and 1/2 cup warm water.

Combine: Pour the wet mix into the dry. Stir with a spatula until a thick, scoopable batter forms. It should be dense but not dry. If it seems stiff, add 1–2 tablespoons more warm water.

Optional boosters: For extra structure and a higher rise, mix in 1–2 teaspoons finely ground psyllium husk. For flavor and crunch, fold in 2–3 tablespoons seeds or 1 teaspoon dried herbs.

Pan and shape: Scoop the batter into the prepared pan. Smooth the top with a damp spatula. Score a shallow line down the center to help it rise evenly.

Bake: Place on the middle rack and bake 40–50 minutes, until the top is firm and deep golden and a toothpick comes out clean. If the top browns too fast, tent with foil in the last 10 minutes.

Cool properly: Let the loaf cool in the pan for 10 minutes. Lift it out by the parchment and cool fully on a rack, at least 1 hour, before slicing. This sets the crumb and prevents gumminess.

Slice and serve: Use a serrated knife to cut into 12–14 slices. Enjoy fresh, toasted, or grilled.
