Preheat your oven to 400°F (200°C). Get an 11x17 inch baking pan ready by greasing it, then lining it with parchment paper, and greasing the parchment paper too. This makes cleanup and serving a breeze!
In a blender, combine the eggs, your choice of plant-based milk, the cooled melted butter, and vanilla extract. Give it a quick whirl just until everything is mixed.
Now, add the almond flour, sweetener, coconut flour (if using), baking powder, and salt to the blender. Blend again until your batter is wonderfully smooth. Let the batter sit for a few minutes; this helps it thicken up perfectly.
Pour the pancake batter into your prepared baking pan and gently spread it evenly all the way to the edges using an offset spatula or the back of a spoon. Sprinkle those delicious sugar-free chocolate chips generously over the top.
Bake for 12 to 15 minutes. You'll know your sheet pan pancake is ready when the edges are beautifully golden and the center feels firm to the touch.
Carefully remove the pan from the oven and let it cool for a few minutes. Then, slice your giant, healthy pancake into 15 perfect large squares.
Serve warm with a pat of butter and a drizzle of your favorite low-carb pancake syrup for a quick, wholesome breakfast or brunch!
