Preheat oven to 350 degrees Fahrenheit
Line a bread pan with parchment paper and set aside.
In a large bowl, mix the dry ingredients together: protein powder, coconut flour, bread flour, sugar, flaxseeds, and baking soda. Stir well to combine.
Add in the wet ingredients: yogurt, almond milk, lemon zest and juice, lemon extract, vanilla extract, and poppyseeds.
Place dough into the bread pan, and place in oven. Bake for 60 minutes until a toothpick can be inserted into the middle and comes out clean. Enjoy!
