Irresistibly Fudgy Vegan Chocolate Peanut Butter Swirl Brownies: Your Ultimate Plant-Based Indulgence
Prepare yourself for pure bliss! These Vegan Chocolate Peanut Butter Swirl Brownies are incredibly addictive, boasting a perfect balance of chewy and fudgy textures. They are deeply rich in both chocolate and peanut butter flavors, and surprisingly simple to whip up!




Making Your Vegan Brownies Perfect: Tips & Tricks
Achieving the perfect fudgy and chewy brownie requires a few key considerations. First, ensure your ingredients are at room temperature where specified, as this helps them combine more smoothly. When melting your chocolate chips, do so gently to avoid seizing; the microwave method in short bursts or a double boiler are both excellent choices. Resist the urge to overmix the batter once the dry ingredients are added; overmixing develops gluten, leading to tougher brownies. A light hand will keep them tender and fudgy.
Another crucial tip is not to overbake! Brownies continue to cook slightly as they cool, and pulling them from the oven when the center is still a *little* wobbly or a toothpick comes out with moist crumbs (not wet batter) is ideal for that ultra-fudgy texture. Remember that cooling completely is also essential. Warm brownies are delicious, but they firm up and become truly fudgy once they’ve reached room temperature, making them much easier and cleaner to cut.
The Art of the Peanut Butter Swirl
Creating that beautiful, distinct peanut butter swirl is simpler than it looks, but there’s a technique to it. After pouring your chocolate brownie batter into the pan, warm your peanut butter slightly until it’s extra runny. This makes it easier to dollop and swirl. Drop medium-sized circles of peanut butter onto the batter, ensuring they don’t touch each other too much initially. Then, take a knife or a skewer and gently drag it through the batter, first left to right, then up and down. The goal is to create ribbons of peanut butter, not to fully incorporate it. Avoid overdoing the swirling, as this can muddle the distinct layers and you’ll lose that gorgeous contrast. A few careful passes are all you need to achieve a stunning marbled effect that’s as appealing to the eye as it is to the taste buds.
Gluten-Free Adaptation
For those with dietary restrictions, I have fantastic news! Several readers have successfully made this recipe gluten-free. My top recommendation for swapping out the all-purpose flour is Bob’s Red Mill Gluten Free 1 to 1 Baking Flour. This particular blend is designed to replace regular flour cup-for-cup in most recipes, making the conversion incredibly straightforward. So, if you’re looking for a delicious, fudgy, and chewy treat that accommodates a gluten-free lifestyle, these peanut butter swirl brownies are an absolute must-try. Enjoy every delightful bite!
Storage and Serving Suggestions
Once cooled, these vegan chocolate peanut butter swirl brownies can be stored in an airtight container at room temperature for up to 3-4 days. For longer freshness, they can be refrigerated for up to a week. To enjoy them warm and extra gooey, simply pop a brownie in the microwave for 10-15 seconds. These brownies also freeze beautifully for up to 2-3 months. Wrap individual brownies tightly in plastic wrap, then place them in a freezer-safe bag or container. Thaw at room temperature or gently reheat.
These brownies are fantastic on their own, but if you’re feeling extra indulgent, consider serving them warm with a scoop of vegan vanilla ice cream, a drizzle of extra peanut butter, or even a sprinkle of sea salt to enhance the flavors. They pair wonderfully with a hot cup of coffee or a cold glass of plant-based milk for an ultimate treat.
I truly can’t wait for you to try these incredible Vegan Chocolate Peanut Butter Swirl Brownies. They are a testament to how satisfying and delicious plant-based desserts can be. Please give them a try and savor every moment. Don’t forget to share your creations and feedback!

Ingredients
- 1 cup chocolate chips, melted, 188g
- 1 cup all purpose flour, 133.75g
- 1/2 teaspoon sea salt
- 1/4 teaspoon baking soda
- 2 flax eggs, – Learn how to make a flax egg OR use 2 Bob’s Red Mill Egg Replacers*
- 3/4 cup brown sugar (I use raw brown sugar, cane sugar or coconut sugar), 158g
- 6 tablespoons melted coconut oil, 75g
- 1/4 cup water
- 1 teaspoon pure vanilla extract
- ¼ cup peanut butter
Instructions
- Preheat oven to 325°F/165°C. Grease and prepare the brownie pan and set it aside.
- Melt chocolate chips in microwave for a minute, stirring after to see if chips have melted. If not, microwave in increments of 30 seconds until completely melted. Alternatively, you can melt in over a small pot of boiling water (Not a lot of water in the pot) and put the chocolate chips it in a heat proof and melt proof bowl over the pot and stir until melted.
- In a medium bowl, whisk the flour, salt and baking soda until combined. Set aside.
- In a separate bowl, add the flax eggs or egg replacement, coconut sugar and coconut oil and mix until combined for about 2 minutes. Add the water and the vanilla extract. Add to the dry mixture to the wet mixture and melted chocolate chips and stir for about 3 minutes until combined.
- Pour into a greased, parchment lined, or a greased foil-lined 8×8 square pan.
- Warm up the peanut butter for about 15 seconds until warm and extra runny. Dollop the peanut butter on top of the brownies. I like to do it in medium circles that don’t touch all over the batter, then slowly using a knife, swirl left to right from top to bottom through the batter, up and down from right to left to get the swirl through the whole batter. Don’t over do it or you’ll just get a muddle.
- Bake for 40-45 minutes. The centre might still be a bit wobbly. When finished, remove from oven carefully and allow to cool completely until room temperature. Cut and enjoy!
