Gluten-Free Brownies (Perfect Crinkle Top!)
There’s something undeniably magical about a batch of freshly baked brownies, especially when they come with that perfect crinkle top that beckons you to take a bite. These Gluten-Free Brownies (Perfect Crinkle Top!) are rich, fudgy, and deeply chocolatey, making them a delightful treat for everyone, whether they follow a gluten-free diet or not. With a combination of simple ingredients and a straightforward process, you’ll be indulging in these decadently chocolatey squares in no time.
Why It Works Every Time
The secret to achieving that perfect crinkle top lies in the method and the ingredients. By using melted butter and mixing the sugars thoroughly, we create a glossy batter that bakes to perfection. The addition of eggs at room temperature ensures they emulsify well, contributing to the fudgy texture and that coveted crackly surface. Plus, using a blend of gluten-free all-purpose flour and raw cacao powder provides both structure and a deep chocolate flavor, making these brownies irresistible.
Ingredient Breakdown
- 1 cup (240g) unsalted butter, melted: Adds richness and moisture.
- 2 Tbsp (30ml) avocado oil: Enhances the texture without overpowering the flavor.
- 1 cup (200g) granulated cane sugar: Contributes sweetness and helps create that shiny top.
- 1 cup (200g) light brown sugar, tightly packed: Adds depth of flavor with its molasses content.
- 1 Tbsp (15ml) pure vanilla extract: Provides a warm, aromatic flavor that complements chocolate.
- 4 large eggs at room temperature: Essential for binding and creating a fudgy texture.
- 1 cup (120g) gluten-free all-purpose flour: Acts as the base for the brownies, providing structure.
- 1 cup (100g) raw cacao powder: Delivers intense chocolate flavor.
- 2 Tbsp instant coffee or espresso powder: Enhances the chocolate flavor (optional but recommended).
- ½ tsp sea salt to taste: Balances the sweetness and enhances overall flavor.
- 1 cup (170g) semi-sweet chocolate chips or chopped chocolate bars: Adds melty pockets of chocolate goodness.
Must-Have Equipment
- Baking pan: An 8×8 inch pan works perfectly for these brownies.
- Mixing bowls: A large bowl for the wet ingredients and a medium bowl for the dry ingredients.

Gluten-Free Brownies (Perfect Crinkle Top!), Made Easy

Step 1: Prepare the Oven and Pan
Preheat your oven to 350°F (175°C). Line your baking pan with parchment paper, leaving some overhang on the sides for easy removal later.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, combine the melted butter and avocado oil. Add the granulated sugar, brown sugar, and vanilla extract. Whisk together until the mixture is smooth and glossy.
Step 3: Add the Eggs
Add the eggs one at a time, whisking well after each addition. Ensure that the mixture is fully combined and slightly thickened.
Step 4: Combine the Dry Ingredients
In a medium bowl, sift together the gluten-free all-purpose flour, raw cacao powder, instant coffee or espresso powder, and sea salt. This step helps to eliminate lumps and ensures even distribution of the dry ingredients.
Step 5: Bring It All Together
Gradually fold the dry ingredients into the wet mixture using a spatula. Be careful not to overmix; just combine until no streaks of flour remain.
Step 6: Add Chocolate Chips
Fold in the semi-sweet chocolate chips or chopped chocolate bars until evenly distributed throughout the batter.
Step 7: Bake
Pour the brownie batter into the prepared baking pan, spreading it evenly. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter).
Step 8: Cool and Enjoy
Allow the brownies to cool in the pan for about 10 minutes before using the parchment paper overhang to lift them out. Let them cool completely on a wire rack before cutting into squares.
Substitutions by Diet

- Dairy-Free: Replace unsalted butter with coconut oil or a dairy-free butter substitute.
- Egg-Free: Use 1/4 cup unsweetened applesauce or 1/4 cup mashed banana per egg.
- Lower Sugar: Substitute granulated sugar with coconut sugar or a sugar alternative like monk fruit sweetener.
- Nut-Free: Ensure your gluten-free flour blend is nut-free if allergies are a concern.
Pro Tips & Notes
- For an extra fudgy brownie, slightly underbake them—remove them from the oven when the edges are set but the center still looks a bit wet.
- Let the brownies cool completely before cutting; this helps them firm up and makes for cleaner cuts.
- Feel free to add nuts or dried fruit for added texture and flavor.
- For a fancy touch, sprinkle a little sea salt on top before baking for a sweet and salty contrast.
Storage & Reheat Guide
Store leftover brownies in an airtight container at room temperature for up to 3 days. For longer storage, place them in the refrigerator, where they can last for up to a week. You can also freeze brownies for up to 3 months. Just wrap them tightly in plastic wrap and then in aluminum foil. To reheat, simply microwave for a few seconds or let them come to room temperature before enjoying.
Popular Questions
Can I use a different type of flour in this recipe?
While this recipe is specifically designed for gluten-free all-purpose flour, you can experiment with other gluten-free flours, but the results may vary. Make sure the blend contains xanthan gum for the best texture.
Why are my brownies not crinkling?
The crinkle top is usually a result of properly mixing the batter to incorporate air. Ensure you whisk the sugars and melted butter together thoroughly and that your oven is the right temperature.
Can I make these brownies in advance?
Absolutely! These brownies can be made a day in advance. Just make sure to store them properly to keep them fresh. They often taste even better the next day!
What can I serve with brownies?
Brownies are delicious on their own but can be elevated with a scoop of vanilla ice cream, a drizzle of chocolate sauce, or a dollop of whipped cream. Fresh berries also make a lovely accompaniment.
