Ready Time

1 hrs 10 mins

Yields

8 servings

Ingredients

2 cups fresh or frozen blueberries
1 1/2 cups all-purpose flour
1 cup granulated sugar
2 teaspoons baking powder
1 teaspoon salt
1/2 cup unsalted butter, softened
1/2 cup confectioners’ sugar
1 teaspoon vanilla extract
1/4 cup rolled oats

Instructions

Preheat your oven to 375°F (190°C).

Line an 8-inch square baking dish with parchment paper or aluminum foil, leaving some overhang on the sides for easy removal.

In a medium bowl, whisk together the flour, sugar, baking powder, and salt.

Add the softened butter and use a pastry blender or your fingertips to work it into the dry ingredients until the mixture resembles coarse crumbs.

Press half of the crumb mixture into the prepared baking dish.

Bake for 20-25 minutes, or until lightly golden brown.

While the crust is baking, mix the confectioners’ sugar and vanilla extract in a small bowl.

Set aside.

In a large bowl, toss the blueberries with the remaining crumb mixture until they’re evenly coated.

Remove the baking dish from the oven and top the warm crust with the blueberry mixture.

Sprinkle the oats over the blueberries.

Drizzle the confectioners’ sugar mixture over the top of the bars.

Use the remaining crumb mixture to sprinkle over the top.

Return the dish to the oven and bake for an additional 35-40 minutes, or until the crust is golden brown and the filling is bubbly.

Let the bars cool completely in the pan before cutting into 8 equal pieces and serving.

Notes

Use fresh or frozen blueberries for this recipe, whichever is convenient for you. Make sure to thaw frozen blueberries first and pat them dry with a paper towel to remove excess moisture.

To ensure the crumb mixture resembles coarse crumbs, don’t overwork the butter into the dry ingredients.

You want it to be crumbly, not pastry-like. Press the crust mixture into the prepared baking dish evenly, making sure to get it into the corners.

This will help the crust bake evenly and prevent it from becoming too thick in some areas.

If using frozen blueberries, you may need to adjust the baking time slightly, as they can release more moisture than fresh blueberries. To get a clean cut, use a sharp knife and wipe it clean between cuts.

This will help prevent the bars from tearing.

Store any leftovers in an airtight container at room temperature for up to 3 days. These bars are perfect for brunch or a sweet snack.
