Step One: Preheat the oven and line a baking tray with parchment paper, then combine flour, powdered sugar, salt, and cornstarch in a large bowl.
Step Two: Add lemon zest and stir well.
Step Three: Gradually mix in melted coconut oil until the dough holds together.
Step Four: Let the dough sit for a few minutes.
Step Five: Form dough into balls and place on the prepared baking sheet.
Step Six: Gently press a thumb or spoon into each ball to create wells. If the dough starts to crack, simply press it back together.
Step Seven: Fill each well with blueberry jam. If the jam is too firm, gently microwave for a few seconds.
Step Eight: Bake until the edges are lightly golden, then cool before serving.
Substitutions & Variations
If you’re interested in tweaking this recipe, you’ll be glad to hear that there are some variations you can make. Here are some tested substitutions I recommend:
- Flour: Use gluten-free all-purpose flour for a gluten-free option.
- Powdered Sugar: Substitute with powdered cane sugar or coconut sugar.
- Cornstarch: Use arrowroot powder or potato starch as alternatives.
- Coconut Oil: Try vegan butter or olive oil for a different fat.
- Blueberry Jam: Replace with raspberry or strawberry jam for a fruity twist. You can even use lemon curd, adding uncooked curd into the wells before baking or cooked curd after baking.
- Lemon Zest: Use lime zest for a citrus variation.
Storage
Store the cookies in an airtight container at room temperature for up to three days. For longer storage, keep them in the refrigerator for up to a week. To enjoy them warm, reheat in the oven at 350°F (175°C) for a few minutes or microwave briefly, allowing them to cool slightly before serving.
Expert Tips
Make sure the coconut oil is melted but not too hot to avoid the dough from becoming too runny. Allowing the dough to sit for a few minutes helps it hold its shape better during baking. Learn more about how to use coconut oil in baking in this post by The Kitchn.
