Expert Tips
- Measure your baking ingredients accurately: Check out my helpful guide on how to measure basic ingredients.
- Butter Temperature: Ensure the melted butter is warm, not hot, to avoid cooking the eggs when mixed.
- Swirling Technique: Use a gentle hand when swirling the peanut butter to maintain distinct layers.
- Do not overbake: To ensure a fudgy brownie, insert a toothpick into the middle and it should come out with some moist crumbs, not completely clean. Slightly under-baking will create a fudgy texture.
Can I use chunky or smooth peanut butter?
Yes, both smooth and chunky peanut butter work well, depending on your texture preference.
How do I know when the brownies are done?
They’re perfect when a toothpick comes out with moist crumbs. Overbaking can lead to dry brownies.
What to do with failed brownies?
Failed brownies can be repurposed into brownie trifles, parfaits, ice cream toppings, brownie bites, or as the base for brownie bread pudding, transforming them into delicious new desserts.
How To Store Chocolate Brownies
Store: In an airtight container at room temperature for up to 3 days or refrigerate for 4-5 days.
Freeze: Cool the brownies completely, then slice. Place slices in an airtight container, separating layers with parchment paper. Freeze for up to 3 months.
Thaw: Remove the desired number of brownies from the freezer and let them thaw at room temperature for several hours before serving.

Easy Peanut Butter Swirl Brownies
Ingredients
Chocolate Brownies
- 100 g salted butter melted
- 2 large eggs, at room temperature
- 1 cup granulated sugar, golden or white
- 1 tsp vanilla extract
- 1/4 cup extra virgin olive oil
- 1/3 cup all-purpose flour
- 2/3 cup unsweetened natural cocoa powder
Peanut Butter Swirl
- 1/3 cup peanut butter, smooth or crunchy
- 1/2 Tbsp coconut oil
Instructions
- Preheat Oven: Preheat the oven to 350ºF (180ºC). Line a square 9-inch x 9-inch (22cm x 22cm) baking pan with parchment paper and set aside.
- Melt Butter: Melt the butter and let it cool for 5 minutes until not too warm.
- Mix Wet Ingredients: In a large mixing bowl, combine the cooled melted butter, eggs, sugar, and vanilla. Beat on medium speed for 2 minutes until well combined. Scrape down the sides.
- Add Oil: Gradually drizzle in the olive oil while beating, to emulsify about 1 minute in total.
- Incorporate Dry Ingredients: Sift in the flour and cocoa powder. Beat until incorporated and no streaks of flour remain. Avoid over-mixing.
- Prepare Batter: Spread the batter evenly in the lined pan.
Peanut Butter Swirl
- Melt: Gently heat the peanut butter and coconut oil in a small saucepan over low heat until melted and combined.
- Swirl: Dollop the peanut butter mixture onto the brownie batter and use a butter knife to swirl it through the batter.
- Bake: Bake for 20-23 minutes or until a toothpick inserted into the middle comes out with some moist crumbs, not completely clean. Slightly under-baking will create a fudgy texture.
- Cool: Remove from the oven and allow to cool in the pan for 20 minutes before transferring to a wire rack to cool completely.
Notes
- Store: In an airtight container at room temperature for up to 3 days or refrigerate for 4-5 days.
- Freeze: Cool the brownies completely, then slice. Place slices in an airtight container, separating layers with parchment paper. Freeze for up to 3 months.
- Thaw: Remove the desired number of brownies from the freezer and let them thaw at room temperature for several hours before serving.

Tried your recipe for today’s office brunch (no vegetarian nor vegans around), and they loved it! Really needed to force myself to not eating the entire batch on my own after getting it out of the oven yesterday amazing! Just wondering about the nutritional facts- any idea? Much love from Germany,
Rebecca
Hi Rebecca, great to hear yourself and everyone enjoyed these brownies! Can’t go wrong with chocolate and peanut butter 🙂
As of right now I unfortunately don’t have a nutritional panel for my recipes, I’m currently working on getting one. So I can definitely report back to you on here once I have that information if you would like.
Thanks Rebecca!
I’ll gonna do it for sure! I just not sure about the applesauce, I never use it before, but I’ll try it anyway! I’ll let you know later 🙂
Hi Vanessa! Yay! I hope you enjoy the recipe. You can’t taste the applesauce in the brownies (well I don’t personally think so). Another option could be using mashed bananas instead of the applesauce. I haven’t tried this before but I think this could be a good option if you don’t want to use applesauce. It will just alter the texture/flavour of the end result. Let me know how you go! xx
Yes. So. Much. Yes. These look absolutely INCREDIBLE!!!
Thanks so much Karly!! These absolutely taste just as good as they look! *drool worthy* xx
