Key Ingredients and Swaps
- Butternut squash: Cooked and mashed until smooth, it adds moisture, natural sweetness, and body. Make sure the squash is well drained and cooled before mixing it into the batter.
- Plain Greek yogurt: Helps create a moist, tender texture. Use plain, unsweetened yogurt.
- Pure maple syrup: Sweetens the brownies and adds a subtle maple flavor. Use pure maple syrup rather than pancake syrup. You can also swap for date syrup or honey.
- Eggs: Provide structure and help the brownies hold together. For egg-free option, check out my Top Egg Replacements and Tips for Optimal Results post.
- Extra-virgin olive oil: Replaces butter and helps keep the brownies moist. You can swap for liquid coconut oil or avocado oil.
- Gluten-free all-purpose flour blend: Choose a gluten-free blend designed for baking. Add ¼ teaspoon xanthan gum if your blend does not already contain it.
- Pure cocoa powder: Provides the deep chocolate flavor. Use unsweetened cocoa powder.
- Gluten-free chocolate: Chopped chocolate or chocolate chips add rich pockets of melted chocolate throughout the brownies.
Gluten-free reminder: Make sure all packaged ingredients you use are labeled gluten-free or verified by the manufacturer. Shop my favorite gluten-free products and baking essentials in my Amazon Store.

Tips and FAQs
How do I prepare butternut squash for brownies?
Peel and cube the squash, then steam for about 15 minutes or until fork-tender. Drain well, mash until smooth, and let it cool before measuring one cup for the recipe.
How do I know when the brownies are done?
The top should look set, and the center should no longer appear liquid. Avoid overbaking, as these brownies are meant to be moist. A toothpick may pick up moist crumbs or melted chocolate.
Can I use chocolate chips instead of a chocolate bar?
Yes. Use about 1 cup of gluten-free chocolate chips in place of the 3.5-ounce chopped chocolate bar.
Should I cut the brownies while warm?
Let them cool completely for cleaner slices and a firmer texture. If you prefer warm brownies with soft, melted chocolate, serve them slightly warm after they have had time to set.

Serving Ideas for Brownies
Enjoy these brownies slightly warm while the chocolate is soft, or let them cool completely for a fudgier texture. Serve them with vanilla ice cream, fresh berries, or a cup of coffee or tea for a simple dessert or afternoon treat.
How to Store Gluten-Free Butternut Squash Brownies
Room temperature: Once completely cool, store the brownies in an airtight container for up to 2 days in a cool environment.
Refrigerate: Store in an airtight container in the refrigerator for up to 5 days. Let them sit at room temperature briefly before serving for a softer texture.
Freeze: Wrap individual squares and place them in a freezer-safe container for up to 2 months. Thaw in the refrigerator or at room temperature. Warm a brownie briefly in the microwave if you prefer the chocolate soft and melted.
