Make It Your Way

The beauty of this Vegan Cosmic Brownies Recipe is how flexible it is—you can easily tailor it to your taste or dietary needs without losing that rich, fudgy goodness. Whether you want to twist the flavors or swap ingredients, these brownies are the perfect canvas.

Nut-Free Variation: I swapped the almond butter for sunflower seed butter the last time I made these for a friend with nut allergies. The texture stayed just as creamy and the subtle nuttiness was still there, just different—delicious in its own way!
Flour Substitution: Using oat flour instead of almond flour makes these brownies gluten-free and adds a slight chewiness that pairs wonderfully with the fudgy texture. Plus, oat flour is often more accessible and budget-friendly.
Sweetener Swap: If you prefer a lower glycemic index sweetener, try monk fruit sweetener in place of coconut sugar. It keeps the brownies just as sweet and reduces the overall sugar content without sacrificing flavor.
For Extra Fudginess: Add an extra tablespoon of melted coconut oil or almond butter to the batter. I love how this makes the edges gooey while keeping the center dense and chocolatey.
Seasonal Twist: Stir in some orange zest or a pinch of cinnamon into the batter for a festive flair. It gives the brownies a unique aroma that’s perfect for holidays or cozy evenings.

Step 1: Preheat the Oven & Prepare Your Pan

Set your oven to 350°F and line an 8×8 inch baking pan with parchment paper. I like to lightly spray the parchment with non-stick spray, especially around the edges. This little extra step helps the brownies pop out perfectly without sticking or tearing when you slice them later.

Step 2: Make Your Flax Eggs

In a small bowl, combine 2 tablespoons of ground flaxseed with 6 tablespoons of water. Whisk well and let it sit for 8 to 10 minutes. This allows the mixture to thicken and mimic the binding power of eggs—essential for that perfect brownie texture!

Step 3: Mix the Wet Ingredients Until Smooth

In a large mixing bowl, whisk together the coconut sugar, almond butter, melted coconut oil, vanilla extract, and your thickened flax eggs. The goal here is a smooth, well-combined base. The batter will start to smell like sweet chocolate and almond heaven—such a tease for what’s to come!

Step 4: Combine the Dry Ingredients and Form Your Batter

In a separate bowl, sift together the almond flour, cacao powder, baking powder, and sea salt. Adding these dry ingredients to your wet mixture in one go, fold gently with a spatula until everything comes together into a thick and luscious brownie batter. Don’t overmix—just enough to incorporate.

Step 5: Fold in Vegan Chocolate Chips and Bake

Stir in the vegan dark chocolate chips last for those pockets of melty goodness. Spread the batter evenly in your prepared pan, smoothing the top with your spatula. Bake at 350°F for 17 minutes—when done, the edges will look set but the center should still be slightly soft. Let the brownies cool in the pan for 15-20 minutes so they firm up just right.

Step 6: Prepare the Creamy Coconut Chocolate Frosting

While the brownies cool, scoop the solid part of the canned coconut cream into a small saucepan (discard or save the liquid part for smoothies). Over low heat, whisk in ½ cup vegan dark chocolate chips constantly until smooth and melted. This luscious frosting is thick, creamy, and oh-so-rich—perfect topping for our cosmic creation.

Step 7: Frost, Sprinkle, and Chill

Pour or spoon the chocolate coconut frosting over your cooled brownies, spreading it evenly. Now is the fun part—add your choice of colorful sprinkles to capture that iconic cosmic vibe. Place the pan in the freezer for 1 hour to let the frosting firm up, so every bite has that satisfying texture contrast.

Step 8: Serve and Store

After chilling, remove the pan from the freezer and cut into 12 generous squares. These brownies are best enjoyed chilled or at room temperature. Store any leftovers in the fridge for up to 5-6 days to keep that fresh, fudgy texture intact.

Top Tip

Making the perfect batch of Vegan Cosmic Brownies takes a little finesse, and these tips will help you achieve that rich, fudgy, and beautifully topped treat every time.

Flax Egg Consistency: Make sure to let your flax eggs rest for a full 8-10 minutes so they thicken properly, or your brownie batter might be too loose.
Cool Before Frosting: >Patience is key! Allow the brownies to cool completely before spreading on the coconut chocolate frosting to avoid it melting and becoming runny.
Freeze to Firm Up: Placing the frosted brownies in the freezer for 1 hour helps the frosting set perfectly for those classic cosmic brownie bites.
Use Full-Fat Coconut Cream: Always refrigerate your coconut cream overnight and scoop only the solid part for that decadent frosting texture—liquids will water it down.

Garnishes

The vibrant sprinkles on top aren’t just for show—they add a playful, colorful pop that evokes the nostalgic vibe of the original cosmic brownies. Feel free to experiment with your favorite vegan-friendly sprinkles or even edible glitter for an extra festive touch.

Side Dishes

These brownies pair wonderfully with a scoop of vegan vanilla ice cream or a dollop of coconut whipped cream for an indulgent dessert. For a lighter pairing, try fresh berries or a cup of rich, plant-based hot chocolate to complement the deep chocolate flavors.

Make Ahead and Storage

Storing Leftovers

Store any leftover Vegan Cosmic Brownies in an airtight container in the fridge. They stay fresh and fudgy for up to 5-6 days—perfect for enjoying a little sweet treat throughout the week.

Freezing

If you want to keep these brownies longer, wrap individual squares tightly and freeze them. They keep well for up to 2 months. Thaw in the refrigerator before serving to maintain their texture and flavor.

Reheating

For a warm, melty experience, microwave a brownie square for about 10-15 seconds. Just be careful not to overheat, or you might melt the frosting too much. Enjoy as is or with your favorite plant-based ice cream.

Frequently Asked Questions:

Can I substitute flax eggs with something else?

Yes! While the Vegan Cosmic Brownies Recipe calls for flax eggs, you can substitute them with 2 regular eggs if you’re not strictly vegan. Aquafaba (chickpea brine) or chia eggs also make great vegan alternatives.

Is it necessary to refrigerate the brownies?

Yes, refrigerating helps maintain the texture and keeps the coconut chocolate frosting firm. The brownies will stay fudgy and fresh for about 5-6 days when stored in the fridge.

Can I use a different nut butter?

Definitely! Almond butter is suggested for its mild flavor, but you can swap it with peanut butter, sunflower seed butter, or any nut/seed butter you prefer without affecting the overall yumminess.

What if I don't have coconut cream?

Coconut cream is essential for that rich, creamy frosting. If you don't have canned coconut cream, you can refrigerate a can of full-fat coconut milk overnight and scoop out the solidified cream portion for use.
