Preheat oven to 350.
Line an 8x4 or 9x5 loaf pan with parchment paper (rub coconut oil inside the cavity before placing the parchment paper on top, so that the parchment paper sticks).
In a medium bowl, mix together the dry ingredients.
In a small bowl, whisk together the wet ingredients, including the lemon zest, and leaving out the blueberries.
Next, pour the wet ingredients into the bowl with the dry ingredients, folding in the blueberries last.
Pour batter into the loaf pan and bake for 40 ish minutes.
Remove from oven and let cool completely. Resist the temptation to dive in right away!
Melt the coconut butter and drizzle on top, slice, and dig in!
If you want more sweetness in the glaze, add 1 tsp of maple syrup to the coconut butter. Enjoy!
