How do I know when it is done?

Use the timing as a guide, then check the center with the recipe's doneness cue, such as a clean toothpick, set edges, bubbling filling, or a gently springy top.

Can I change the flavor?

Yes. Keep changes small the first time, such as adding citrus zest, spice, chocolate, nuts, or a simple glaze that matches the recipe.

What should beginners watch most closely?

Measure carefully, avoid overmixing batters or doughs, and let the bake cool long enough before slicing, glazing, or storing.

Instructions

Preheat your oven to 350 degrees F (175 degrees C). Line an 8x8-inch (20x20 cm) square baking pan with parchment paper, leaving an overhang on two sides for easy removal.
In a large bowl, whisk together whole wheat flour, rolled oats, chia seeds, ground flaxseed, baking powder, baking soda, and salt until evenly mixed.
In a separate medium bowl, beat the eggs with maple syrup, unsweetened applesauce, Greek yogurt, and vanilla extract until smooth and combined.
Pour the wet ingredients into the dry ingredients. Gently stir just until combined. Avoid overmixing to keep the bars tender.
Fold in the blueberries and lemon zest if using, distributing evenly throughout the batter.
Spread the batter evenly in the prepared pan using a spatula.
Bake for 22 to 25 minutes, or until the top is golden and a toothpick inserted into the center comes out clean or with a few moist crumbs.
Let the bars cool in the pan for at least 15 minutes.
Lift the bars from the pan using the parchment paper edges and transfer to a wire rack to cool completely before cutting into 12 bars.
Store bars in an airtight container at room temperature for up to 3 days, refrigerate for up to 7 days, or freeze wrapped tightly for up to 3 months.
