How to Make It

1. Preheat the oven

Set your oven to 350°F (175°C).

Line a 9×13 baking pan with parchment paper. This step saves your sanity later when removing the bars.

2. Make the crust

In a bowl, mix melted butter, flour, powdered sugar, and salt.

Stir until the mixture looks like soft dough. Press it evenly into the bottom of the baking pan.

Bake for 15–18 minutes until the crust looks lightly golden.

Your kitchen should already smell amazing.

3. Prepare the filling

While the crust bakes, grab another bowl.

Whisk together:

• eggs

• sugar

• flour

• lemon juice

• lemon zest

• vanilla extract

Mix until smooth. No lumps allowed.

4. Add the blueberries

Gently fold in the blueberries.

Try not to smash them. They’re delicate little flavor balloons.

5. Pour and bake

Pour the lemon blueberry mixture over the warm crust.

Spread it evenly.

Bake again for 22–25 minutes until the center is set.

The filling should jiggle slightly but not look liquid.

6. Cool and chill

Let the bars cool at room temperature first.

Then place the pan in the fridge for 1–2 hours.

Chilling helps the bars firm up. Cutting them becomes much easier.

7. Slice and serve

Dust the top with powdered sugar.

Cut into squares.

Try to stop at just one piece. Good luck with that.
