Make the jam by mashing the blueberries, using a fork, in a pan set over a medium-low heat.
When the mixture becomes bubbly and syrupy, remove from the heat and stir in the chia seeds, maple syrup, and lemon juice. Set aside to cool slightly.
Make the batter by putting all the ingredients (except for coconut oil) in a blender or a food processor. Blitz until smooth and thick.
Heat a teaspoon of coconut oil in a large frying pan over a medium heat. Then, add a few dollops of batter into the pan. Cook for a minute or two on one side, or until the edges are starting to brown and bubbles are starting to form on top.
Once the pancake turns into a nice golden brown color, flip it over with a spatula and cook for another couple of minutes. Set aside and keep warm while you repeat the process with the remaining batter, adding a bit of coconut oil with each batch. You should make about 24 to 36 pancakes.
Assemble your stack by layering the pancakes with a teaspoon of jam and yogurt. On the final layer, dollop any remaining yogurt and jam. Sprinkle with some nuts, seeds, and berries to serve.
