Instructions

  1. Step 1: In a large bowl, beat 1 cup (226g) softened unsalted butter and 1/2 cup (100g) granulated sugar with an electric mixer on medium speed until light and fluffy, about 3 minutes. Add 1 large egg and 1/4 teaspoon blue food coloring, then beat until fully incorporated and pale yellow.
  2. Step 2: Gradually add 2 1/2 cups (300g) all-purpose flour to the butter mixture on low speed until just combined, then gently fold in 1/2 cup (about 100g) halved fresh blueberries until evenly distributed without breaking the berries.
  3. Step 3: Divide the dough into two equal portions, shape each into a 1.5-inch diameter log on parchment paper, wrap tightly, and refrigerate for 2 hours until firm.
  4. Step 4: Preheat oven to 325°F (160°C). Slice logs into 1/4-inch thick rounds, place 1 inch apart on a parchment-lined baking sheet, and bake for 12-15 minutes until edges are lightly golden.
  5. Step 5: Transfer cookies to a wire rack to cool completely, then dust evenly with 1/4 cup (30g) powdered sugar before serving.

Frequently asked questions

How long does Blueberry Swirl Shortbread Cookies take to make?

Total time is about 165 minutes (150 min prep + 15 min cook). Most home bakers find this fits a weekend afternoon; chill or store as the recipe directs before serving.

How do I store leftover Blueberry Swirl Shortbread Cookies?

Cool fully before storing. Most baked desserts keep at room temperature in an airtight container for 2–3 days, or in the fridge for up to 5 days. Cream- or custard-based desserts must go in the fridge within 2 hours; reheat gently or serve cold per the recipe.

Can I substitute ingredients in Blueberry Swirl Shortbread Cookies?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Blueberry Swirl Shortbread Cookies for a different number of people?

The recipe is written for 24 servings. Multiply each ingredient by (your serving target / 24). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

What goes well with Blueberry Swirl Shortbread Cookies?

American desserts like this pair well with a simple grain (rice, couscous, or crusty bread), a quick salad with acid (lemon vinaigrette, pickled onions), and a pan sauce or yogurt-based dip. Tap "Plan a meal with the AI" to get specific side suggestions.
