This beloved recipe, first shared on December 8, 2016, continues to delight dessert lovers worldwide.

This vegan peanut butter sheet cake is incredibly straightforward to prepare, yielding a wonderfully moist and tender crumb every single time. One of its standout features is the innovative blender method, which allows you to whip up the entire cake batter in a mere 5 minutes! If you prefer a more traditional approach, you can certainly mix the batter in a bowl—detailed instructions are provided for both methods to ensure your baking success.

While your delightful cake bakes to golden perfection, you can quickly prepare the luscious 5-ingredient chocolate peanut butter glaze or a creamy peanut butter frosting. Once the cake has cooled, it’s ready for frosting and serving, promising a truly unforgettable dessert experience that tastes far more complex than its simple preparation suggests.

This exceptionally moist vegan peanut butter cake is a delight on its own, but truly shines when paired with its signature glaze or a fluffy frosting. Beyond its deliciousness, it’s a remarkably versatile recipe. Feel free to experiment with any nut butter you have on hand, such as smooth almond butter or creamy cashew butter, for a subtly different flavor profile. For those with nut allergies, sunflower seed butter (sun butter) makes an excellent and equally delicious nut-free alternative.

The chocolate glaze itself is a masterpiece of simplicity, requiring just a few key ingredients: vegan chocolate chips, a splash of non-dairy milk, a touch of coconut oil for sheen and texture, and, of course, creamy peanut butter. This dreamy glaze comes together effortlessly in a saucepan on the stovetop, conveniently prepared while your cake bakes and cools, ensuring a seamless baking process from start to finish.

For an added layer of texture and flavor, consider stirring some chopped peanuts into the cake batter before baking – they provide a delightful crunch. You can also customize your cake by folding in other delicious additions like dried fruits for a touch of sweetness, or extra vegan chocolate chips for an even more intense chocolatey experience.

Key Ingredients and Smart Substitutions

Crafting the perfect vegan peanut butter cake relies on a few core ingredients, each playing a vital role in texture and flavor. Here’s a detailed look at what you’ll need and how you can adapt the recipe to suit your preferences or dietary needs:

• Non-Dairy Milk: This is crucial for adding moisture to both the cake batter and achieving the perfect consistency for the chocolate glaze. Choose your favorite unsweetened variety, such as almond, soy (if not soy-free), oat, or cashew milk. Ensure it’s soy-free if you’re adhering to a soy-free diet.
• Vegan Sugar: Granulated cane sugar works beautifully. If you prefer, coconut sugar can be used for a more complex, caramel-like flavor, or any other vegan-friendly sugar. Adjust the amount by adding an extra 2 tablespoons for a sweeter cake, depending on your preference.
• Maple Syrup: Adds a natural sweetness and contributes to the cake’s moist texture. Agave nectar or a similar liquid sweetener can be used as a substitute, though maple syrup offers a unique flavor depth.
• Vanilla Extract: A dessert essential, vanilla extract enhances all the other flavors in the cake, adding a warm, aromatic note. Don’t skip this!
• Smooth Peanut Butter: The star ingredient! It provides the distinctive flavor and helps create a rich, dense crumb. For the best results, use a creamy, well-stirred peanut butter that doesn’t separate. For a peanut-free version, smooth almond butter or cashew butter are excellent alternatives, offering their own delightful nutty profiles. For a school-friendly or nut-allergy-safe option, sunflower seed butter (sun butter) is a fantastic choice.
• Oil: A touch of neutral oil in the cake batter ensures a tender and moist cake. Vegetable oil, canola oil, or melted coconut oil (ensure it’s refined if you don’t want a coconut flavor) are all good choices. For the glaze, refined coconut oil helps achieve a glossy finish and a smooth texture that sets beautifully.
• Flour: Standard all-purpose flour provides the ideal structure. For added depth and nutrients, you can use a mix of 1.5 cups all-purpose flour and 0.5 cup whole wheat or spelt flour. For a gluten-free option, refer to the specific blend outlined in the “Notes” section of the recipe card – a blend of almond, oat, and potato starch works wonderfully with a slight adjustment in liquid.
• Baking Powder, Baking Soda, and Salt: These leavening agents are vital for achieving the cake’s light and fluffy texture, while salt balances the sweetness and enhances overall flavor. Ensure they are fresh for optimal lift.
• Vegan Chocolate Chips and Dark Chocolate: For the rich glaze, a combination of semi-sweet vegan chocolate chips and chopped dark chocolate (ensure it’s vegan, 60-70% cacao usually works well) creates a deep, complex chocolate flavor and perfect consistency.

Step-by-Step Guide: How to Make Peanut Butter Cake

Follow these simple instructions to bake your own delightful vegan peanut butter cake with chocolate peanut butter glaze:

Step 1: Prepare Your Oven and Pan

Begin by preheating your oven to 350° F (180º C). Lightly grease or line an 8×8 or 9×9 inch brownie pan with parchment paper, leaving an overhang on the sides for easy removal. This ensures your beautiful cake won’t stick.

Step 2: Prepare the Wet Ingredients

For the Blender Method: Add the non-dairy milk, sugar, maple syrup, vanilla extract, smooth peanut butter, and oil (if desired for extra richness) directly into your blender. Blend until the mixture is smooth, ensuring the sugar and peanut butter are fully incorporated. This should only take a minute or two.

For the Bowl Method (as shown in the image below): If you prefer not to use a blender, slightly warm the non-dairy milk to help the peanut butter combine more easily. In a large bowl, whisk together the non-dairy milk, sugar, maple syrup, vanilla extract, smooth peanut butter, and oil until everything is well blended and smooth.

Step 3: Combine Wet and Dry Ingredients

For the Blender Method: Add the flour, baking powder, baking soda, and salt to the wet mixture in the blender. Pulse for only 2 to 3 seconds, then pulse once or twice more until the dry ingredients are just combined into a smooth batter. Avoid overmixing to keep the cake tender.

For the Bowl Method: In a separate medium bowl, whisk together the flour, baking powder, baking soda, and salt. Gently pour the wet peanut butter-milk mixture from Step 2 into the bowl of dry ingredients. Using a spatula or whisk, mix until a smooth batter forms. Again, mix just until combined to prevent a dense cake.

Step 4: Bake the Cake

Carefully pour the smooth batter into your prepared pan. Use a spatula to gently spread and even out the top surface of the batter.

Bake for 21 to 24 minutes, or until a wooden toothpick inserted into the center of the cake comes out clean. Once baked, let the cake cool in the pan for 10 minutes. Then, invert it onto a wire rack to cool completely for at least 15 minutes. This is the perfect time to start making your delicious glaze!

Step 5: Make the Chocolate Peanut Butter Glaze

In a small saucepan, combine the smooth peanut butter, non-dairy milk, coconut oil (if using for extra sheen), and the optional tablespoon of sugar. Place the saucepan over medium-low heat. Stir the mixture frequently until it becomes smooth and just begins to warm through. Once smooth, remove the saucepan from the heat.

To the warm peanut butter mixture, add the vegan chocolate chips and chopped dark chocolate. Stir continuously until all the chocolate has melted and the glaze is completely smooth and glossy. This magical transformation should only take about one minute of gentle stirring.

Step 6: Glaze and Serve Your Masterpiece

Pour the warm, silky glaze evenly over your completely cooled vegan peanut butter cake. Use a spatula to spread it gently from edge to edge, creating a uniform, luscious layer. If desired, garnish with a sprinkle of shaved chocolate, a dusting of cocoa powder, or a scattering of toasted coconut flakes for added appeal. Allow the glaze to set for about 10 minutes at room temperature before slicing into generous portions and serving this truly irresistible dessert.

Storage and Serving Suggestions

To keep your vegan peanut butter cake fresh and delicious, store it in an airtight container at room temperature for up to 2-3 days. If you need to keep it longer, it can be refrigerated for up to 5 days. When serving from the refrigerator, allow the cake to sit at room temperature for about 15-20 minutes to soften the cake and glaze slightly for the best texture. This cake is also freezer-friendly; wrap individual slices tightly in plastic wrap, then in aluminum foil, and store in a freezer-safe bag for up to one month. Thaw slices overnight in the refrigerator or at room temperature for a few hours before enjoying.

This magnificent cake is perfect on its own, but you can enhance the experience by serving it with a scoop of vegan vanilla ice cream, a dollop of coconut whipped cream, or a light dusting of cocoa powder. A sprinkle of flaky sea salt on the glaze can also wonderfully balance and intensify the rich chocolate and peanut butter flavors. Enjoy this delightful dessert as an everyday treat or as a show-stopping finish to any special meal!
