Ultra-rich and fudgy, these Irresistible Peanut Butter Fudge Brownies are the ultimate treat. I swirl creamy peanut butter into a deeply chocolatey brownie base for a moist, decadent dessert that’s hard to resist. Made with wholesome ingredients like oat flour, natural sweeteners, and the option to go completely dairy-free, this recipe strikes the perfect balance between indulgence and feel-good baking.
Why You’ll Love This Recipe
I love how these brownies come together with just a few pantry staples and no complicated steps. The combo of peanut butter and chocolate gives that classic sweet-salty satisfaction I crave, while ingredients like applesauce or mashed banana keep things moist and rich without needing extra oil or butter. Whether I’m baking for a crowd, prepping a snack for the week, or just satisfying a late-night craving, this recipe never lets me down.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1/2 cup peanut butter (natural or regular)
1/4 cup applesauce or mashed banana
1/2 cup pure maple syrup or honey
1/4 cup unsweetened cocoa powder
1/4 cup oat flour
1/4 teaspoon salt
1/2 teaspoon baking soda
2 teaspoons vanilla extract
1/2 cup dairy-free chocolate chips (or regular)
Directions
I preheat my oven to 325°F (163°C) and either grease or line an 8×8-inch baking dish with parchment.
In a mixing bowl, I stir together the peanut butter, applesauce (or mashed banana), maple syrup (or honey), vanilla extract, and cocoa powder until smooth.
I add the oat flour, baking soda, and salt, and mix until just combined.
Then I fold in the chocolate chips.
I pour the batter into the prepared baking dish, smoothing the top evenly.
For a pretty marbled effect, I sometimes swirl in an extra tablespoon of peanut butter on top.
I bake the brownies for 20–25 minutes, until the center is just set and a toothpick inserted comes out mostly clean.
I let them cool completely before slicing to get the best texture.

Variations
I sometimes use almond butter instead of peanut butter for a different flavor twist.
To make these brownies fully vegan, I stick with maple syrup and mashed banana instead of honey or applesauce.
For extra richness, I top the batter with a few extra chocolate chips before baking.
If I want a crunchier texture, I stir in chopped peanuts or walnuts.
I also like using a mix of dark and semi-sweet chocolate chips for depth of flavor.
Storage/Reheating
Once cooled, I store these brownies in an airtight container at room temperature for up to 3 days. If I want them to last longer, I pop them in the fridge where they keep well for up to a week. For that fresh-from-the-oven feel, I warm individual brownies in the microwave for about 10–15 seconds before serving.

FAQs
How can I make these brownies fully vegan?
I use maple syrup instead of honey and mashed banana in place of applesauce to keep the recipe plant-based. Just make sure to use dairy-free chocolate chips too.
Can I freeze these brownies?
Yes, I often freeze them! I wrap individual squares in parchment paper and store them in a freezer-safe container. They thaw beautifully at room temperature or can be microwaved for a quick treat.
What’s a good substitute for oat flour?
If I don’t have oat flour, I grind rolled oats in a blender or food processor until fine. I’ve also tried almond flour for a slightly different texture, though it makes the brownies a bit denser.
Can I make this recipe nut-free?
I haven’t personally tried it, but sunflower seed butter could work in place of peanut butter. Just keep in mind that it may affect the flavor and color slightly.
How do I know when the brownies are done?
I bake them until the center is just set and a toothpick inserted in the middle comes out with only a few moist crumbs. I make sure not to overbake — they continue to set as they cool.
Conclusion
These irresistible peanut butter fudge brownies are one of my favorite easy desserts to whip up. With simple ingredients and a rich, satisfying flavor, they always hit the spot. Whether I’m baking for a special occasion or just treating myself, this recipe delivers every time.
