Steps
Before you start
- Take the eggs out of the fridge 30 minutes ahead so they mix smoothly into the batter.
- Use finely ground blanched almond flour, not coarse almond meal, for a tender crumb.
- You need 2 large lemons: zest them first, then juice them (about 4½ tablespoons of juice in total).
- Plan on about 1 hour of cooling before slicing. This loaf is fragile when warm.
Preheat and line panOven 350°F / 175°C
- Position a rack in the center of the oven and preheat to 350°F (175°C).
- Lightly grease a 9×5-inch (23×13 cm) loaf pan with a little butter from the 4 tablespoons (reserve the rest for the batter).
- Line the bottom and the two long sides with a strip of parchment, leaving a 2-inch overhang to use as handles.

Ready when: Pan is lined with parchment that overhangs both long sides.
Tip: Almond flour loaves stick easily, so don't skip the parchment.
Zest and juice lemons
- Finely grate the zest from 2 large lemons to get 2 tablespoons, avoiding the bitter white pith.
- Then halve the lemons and squeeze them.
- Strain out the seeds and measure 3 tablespoons (45 ml) of juice for the batter; set aside 1½ tablespoons (22 ml) more for the glaze, if using.

Ready when: You have 2 tbsp zest and about 4½ tbsp juice.
Tip: Zest before juicing; a squeezed lemon is nearly impossible to zest.
Mix dry ingredients
- In a medium bowl, whisk together the almond flour, baking powder, baking soda, and salt for 30 seconds, pressing out any lumps with the back of the whisk.

Ready when: The mixture looks uniform with no clumps of baking soda.
Whisk wet ingredients
- In a large bowl, whisk the eggs and honey vigorously for about 1 minute until pale yellow and slightly frothy.
- Whisk in the melted butter, lemon zest, 3 tablespoons lemon juice, and vanilla until fully combined.

Ready when: The mixture is smooth and uniform, with no streaks of honey or butter.
Tip: Let the butter cool for 5 minutes first, or it can scramble the eggs.
Combine batter
- Add the dry mixture to the wet ingredients and stir with a rubber spatula until just combined and no dry pockets remain.
- Sprinkle in the poppy seeds and fold 5 or 6 times to distribute.
- The batter will be thick but pourable, like a loose muffin batter.

Ready when: Batter is evenly speckled with seeds and has no dry flour pockets.
Tip: Stop mixing once combined; there is no gluten to worry about, but overmixing can make the loaf dense and oily.
Fill the pan
- Scrape the batter into the prepared pan and spread it evenly into the corners.
- Tap the pan firmly on the counter twice to release large air bubbles, and smooth the top with the spatula.

Ready when: The batter is level and fills the pan about three-quarters full.
Bake uncoveredOven 350°F / 175°C
- Bake at 350°F (175°C) on the center rack for 30 minutes, until the top is set and light golden.

Ready when: The top is light golden and domed, and the center is starting to set.
Tip: Don't open the oven in the first 25 minutes, or the loaf may sink.
Tent and finish bakingOven 350°F / 175°C
- Loosely cover the loaf with a sheet of aluminum foil to prevent over-browning.
- Continue baking at 350°F (175°C) for 18 to 22 minutes more.
- The loaf is done when a skewer inserted in the center comes out clean or with a few dry crumbs, or when the center reads 205°F (96°C) on an instant-read thermometer.

Ready when: Skewer comes out clean; top springs back lightly when pressed; edges pull slightly from the pan.
Tip: Almond flour browns fast because of the honey, so tent as soon as the top is deep golden.
Cool in pan
- Set the pan on a wire rack and let the loaf cool in the pan for 20 minutes.
- It will firm up and be less likely to break.

Ready when: The loaf is warm, not hot, and feels firm at the edges.
Tip: Don't try to remove it sooner; the crumb is very tender when hot.
Cool completely
- Use the parchment overhang to lift the loaf out of the pan and set it on the wire rack.
- Let it cool completely, about 40 minutes, before glazing or slicing.

Ready when: The bottom of the loaf feels completely cool to the touch.
Glaze and serve
- Whisk the powdered sugar with 1½ tablespoons lemon juice until smooth and thick but pourable, adding more juice a few drops at a time if it is too stiff.
- Drizzle over the cooled loaf and let the glaze set for 15 minutes.
- Slice with a serrated knife into 10 slices using a gentle sawing motion.

Ready when: The glaze is opaque and no longer tacky when touched lightly.
Tip: Glazing a warm loaf makes the glaze soak in and disappear.
Good to know
Tips
- Measure almond flour by weight (250 g) if you can; packing it into the cup can make the loaf heavy and greasy.
- Rub the lemon zest into the honey with your fingertips for a minute before mixing for stronger lemon flavor.
- Use a serrated knife and slice with a gentle sawing motion; the crumb is delicate. Chilling the loaf for 30 minutes makes cleaner slices.
- If your oven runs hot, check the loaf at 40 minutes total; honey makes the crust brown quickly.
Make ahead
"Bake the loaf up to 2 days ahead, cool completely, and wrap tightly at room temperature. Add the glaze on the day you serve it."
Storage & reheating
"Room temperature: up to 2 days in an airtight container (glazed or unglazed). Refrigerator: up to 7 days, wrapped well; bring slices to room temperature or warm in a 300°F (150°C) oven for 5 minutes. Freezer: up to 3 months, sliced and wrapped individually, unglazed; thaw at room temperature for 30 minutes or toast from frozen."
Substitutions
- honey → pure maple syrup. Use the same amount; the flavor will be slightly more caramel-like and the loaf may be a touch less moist.
- unsalted butter → melted coconut oil or light olive oil. Use the same amount; coconut oil should be melted and cooled slightly.
- poppy seeds → chia seeds. Use the same amount for a similar texture; the flavor will be milder and the speckles gray rather than blue-black.
- powdered sugar → powdered erythritol or other powdered sugar substitute. Use the same amount; the glaze may be slightly thinner.
