Blueberry Crumb Butter Cookie

Headnote

This cookie is built on contrast: a tender, buttery base, a restrained brown-sugar depth, and a bright blueberry finish. The crumb is deliberate rather than rustic, giving the cookie a refined texture that stays delicate at the center and crisp at the edges. It is a small sweet with clear structure and a clean, elegant finish.

Tray lined with parchment paper
Fork
Digital scale
Oven

Ingredients

Wheat flour 16 g
Baking powder 0.5 g
Salt 0.2 g
Butter, softened 10 g
Sugar 8 g
Brown sugar 4 g
Egg 5 g, lightly beaten
Vanilla extract 0.3 g
Blueberry 4 g, finely chopped

Method

1. Heat the oven to 180°C. Line a small tray with parchment paper.

2. In a small bowl, combine the wheat flour, baking powder, and salt. Stir once to distribute evenly.

3. In a second bowl, work the butter, sugar, and brown sugar together with a fork until smooth, pale, and slightly aerated, about 1 minute. The mixture should look cohesive rather than grainy.

4. Add the egg and vanilla extract. Mix until fully incorporated and glossy, about 20 seconds.

5. Add the dry ingredients and mix just until a soft dough forms. Fold in the blueberry with minimal handling so the fruit remains distinct.

6. Shape the dough into one round cookie weighing 48 g. Place it on the prepared tray and flatten very slightly; it should hold a neat dome with visible blueberry pieces.

7. Bake for 11 to 12 minutes, until the edges are set and lightly golden and the center remains tender but no longer wet. The cookie should feel delicate to the touch and lift cleanly from the parchment after a brief rest.

8. Cool on the tray for 5 minutes before serving.

Plating and serving

Serve the cookie warm or at room temperature, centered on a small plate. The finish should be modest and precise, with the blueberry visible at the surface and the crumb intact. The texture should read as soft within, lightly crisp at the edge, and cleanly sweet.

Professional notes

Handle the dough minimally once the flour is added; overmixing will tighten the crumb. Keep the blueberry pieces small so they distribute without tearing the dough. Bake only until the center loses its raw sheen; this cookie is meant to remain tender, not dry.
