Preheat and prep: Heat your oven to 350°F (175°C). Line a 9x5-inch loaf pan with parchment paper, leaving a sling for easy removal. Lightly grease the exposed sides.

Mix dry ingredients: In a large bowl, whisk almond flour, flaxseed meal, psyllium husk powder, baking powder, baking soda, salt, and any optional seasonings until evenly combined and lump-free.

Whisk the wet: In another bowl, whisk eggs, almond milk, olive oil, and apple cider vinegar until smooth and slightly frothy.

Combine: Pour the wet mixture into the dry. Stir with a spatula until a thick batter forms. It will look dense at first and then slightly expand as the psyllium hydrates. Let it rest for 2–3 minutes to firm up.

Pan and smooth: Scrape the batter into the prepared pan. Smooth the top with a damp spatula. If using toppings, sprinkle them now and gently press so they adhere.

Bake: Place on the middle rack and bake for 40–50 minutes, until the top is golden and a toothpick inserted in the center comes out mostly clean with a few moist crumbs. A good sign of doneness is a firm dome that springs back lightly to the touch.

Cool properly: Let the loaf cool in the pan for 10 minutes, then lift it out using the parchment sling. Cool completely on a wire rack—at least 1 hour—before slicing. This step prevents a gummy interior.

Slice and serve: Use a serrated knife to cut into 12–14 even slices. Enjoy plain, toasted, or with your favorite toppings.
