Preheat the oven to 350 degrees F. Grease a 9x9 inch pan or 11x7 with oil or nonstick cooking spray and set aside.
In a large bowl, whisk together the eggs, pure maple syrup, lemon zest, lemon juice, melted butter, almond milk, and both vanilla and almond extracts until well combined.
Add the oats, poppyseeds, baking powder, and salt to the wet mixture. Mix until combined, then fold in the blueberries.
Pour mixture into the prepared pan and smooth the top. Bake for 35-45 minutes or until the edges are slightly golden brown and the center is set.
In a small bowl, mix together the Greek yogurt, powdered sugar, 1 teaspoon lemon juice, and zest; mix to combine. Add more lemon juice if necessary to thin it out.
Drizzle the lemon yogurt over the top, cut into 6 slices, and serve!
