Preheat oven to 350 degrees F, line 9 x 5 loaf pan with parchment paper and spray with cooking spray. Set aside.
In a large bowl, add eggs, maple syrup, yogurt, lemon zest and juice, vanilla extract, baking powder, baking soda and salt. Whisk very well until combined and no lumps.
Add almond flour (make sure to level the top with a knife and do not pack) and poppy seeds. Stir gently with spatula until well mixed.
Transfer batter into previously prepared loaf pan, level with spatula and bake on a middle rack for 45-50 minutes or until top is golden brown and a toothpick inserted in the middle comes out dry. Remove from the oven, holding onto parchment paper remove loaf from the pan and let cool for 30 minutes.
While bread is cooling, make glaze by whisking powdered sugar and lemon juice in a small bowl. Drizzle over bread and enjoy!
Notes
Store: Store bread in an airtight container or bag in a cool dry place for up to 3 days. After refrigerate for another 3 days or proceed to freezing.
Freeze: Bake and cool completely. I recommend to freeze bread unsliced to retain moisture. Place in a gallon size Ziploc container, let out as much air as possible and seal. Freeze for up to 3 months. Thaw on a counter.
Don't substitute flour or liquid sweetener: Almond meal might work, just bread will be more dense and rise less. If you use dry sweetener, batter consistency will be off.
Regular and other yogurt: You can use plain regular (not Greek) yogurt, however might have to add 1/4 cup extra almond flour since it contains more liquid. Can also use flavored yogurt. The goal is to bring batter to consistency in the photos.
Fresh lemon juice is the best but bottled will work as well.
