In a mixing bowl, combine the full-fat canned coconut milk, avocado oil (or olive oil), pure maple syrup, and pure vanilla extract. Whisk until well blended and set aside.
In another bowl, whisk together the gluten-free all-purpose flour, baking powder, poppy seeds, lemon zest, and sea salt. Make sure there are no lumps in the flour.
Pour the wet mixture into the bowl with the dry ingredients. Gently stir until just combined. Be careful not to overmix; it’s okay if there are a few small lumps.
Preheat your griddle or non-stick skillet over medium heat. If necessary, lightly grease it with a touch of oil to prevent sticking.
Once the griddle is hot, pour about 1/4 cup of batter for each pancake onto the skillet. Cook for about 3-4 minutes, or until bubbles form on the surface and the edges look set. Flip the pancakes and cook for another 2-3 minutes, until golden brown.
Remove pancakes from the skillet and keep warm while you cook the rest. Serve with additional maple syrup, fresh fruit, or a sprinkle of powdered sugar if desired.
