Best Chestnut Flour Thumbprint Cookies – Gluten-Free & Easy Recipe

She always had a way of turning simple ingredients into something magical, and that day, she handed me a bag of finely ground chestnut flour with a knowing smile.

“Try this in your cookies,” she said. “It’ll remind you of the roasted chestnuts we used to eat by the fireplace.”

I followed her advice, replacing regular flour in my favorite thumbprint cookie recipe. The result? Soft, slightly sweet cookies with a delicate nutty flavor that melted in my mouth. As I filled the warm indentations with homemade raspberry jam, I knew I had discovered something special.

Lisa’s Tips for Perfect Chestnut Flour Thumbprint Cookies

Baking with chestnut flour is a little different from using traditional wheat flour, but with the right tips, you’ll get soft, nutty, and perfectly textured thumbprint cookies every time.

1. Use High-Quality Chestnut Flour

Not all chestnut flours are the same. Look for finely ground chestnut flour with a mild, slightly sweet aroma. Coarser flours can make the cookies dry or grainy.

Tip: Store chestnut flour in an airtight container in the fridge or freezer to keep it fresh longer.

2. Don’t Skip Chilling the Dough

Chestnut flour has a delicate texture, and chilling the dough for 15-20 minutes before rolling helps prevent spreading during baking.

Tip: If the dough feels too soft, refrigerate it for a bit longer before shaping the cookies.

3. Make Deep Thumbprints

Since the cookies puff slightly in the oven, make the thumbprints deep enough to hold the filling without disappearing as they bake.

Tip: Use the back of a teaspoon instead of your thumb for a more uniform shape.

4. Choose the Right Filling

The nutty sweetness of chestnut flour pairs well with a variety of fillings. Here are some favorites:

• Fruit jams (raspberry, apricot, or fig) for a classic, slightly tart contrast.
• Melted dark chocolate for a rich, indulgent twist.
• Nut butters (almond, hazelnut, or peanut) for extra creaminess and protein.

Tip: If using jam, stir it well before adding to prevent uneven textures.

5. Watch the Bake Time

Chestnut flour browns faster than wheat flour, so keep an eye on your cookies. They should be lightly golden on the edges but still soft in the center.

Tip: If your oven runs hot, check the cookies at 9 minutes to avoid overbaking.

6. Let Them Cool Before Moving

Chestnut flour cookies are delicate when warm. Let them cool on the baking sheet for at least 5 minutes before transferring to a wire rack.

Tip: If they seem too crumbly, let them rest a little longer before handling.

7. Store Them Properly

Keep cookies in an airtight container at room temperature for up to 5 days or refrigerate for a longer shelf life.

Tip: For a firmer texture, store them in the fridge and enjoy chilled!

FAQs About Chestnut Flour Thumbprint Cookies

1. Can I substitute chestnut flour with another flour?

Yes, but the texture and flavor will change. Almond flour is the closest substitute, offering a similar nutty taste. You can also use a mix of oat flour and almond flour if you prefer a lighter texture.

2. Why is my dough too crumbly?

Chestnut flour absorbs moisture differently than wheat flour. If your dough feels too dry, try adding an extra teaspoon of melted butter or a splash of milk to help bind it together.

3. What are the best fillings for these cookies?

Traditional jams like raspberry, apricot, or fig work well. For a richer taste, try melted chocolate, nut butters, caramel, or even lemon curd for a citrusy twist.

4. How do I prevent my thumbprints from losing their shape while baking?

Make a deep indentation in the dough before baking, as the cookies slightly puff up in the oven. You can also chill the dough for 15-20 minutes before baking to help maintain its shape.

5. Are these cookies gluten-free?

Yes! Chestnut flour is naturally gluten-free and grain-free, making these cookies a great option for those with gluten sensitivities. Just ensure that all other ingredients used are certified gluten-free.
