Peanut Butter Nutella Swirl Brownies Recipe cooking

Save

1 cup butter (melted) – The secret to rich, fudgy brownies.
2 cups sugar – Brownies are a dessert, not a salad.
3 large eggs – Helps create that perfect chewy texture.
1 teaspoon vanilla extract – Adds depth of flavor.
1 cup all-purpose flour – Gives the brownies structure.
¾ cup cocoa powder – For that deep chocolate goodness.
½ teaspoon salt – Balances the sweetness.
½ cup Nutella – The creamy chocolate-hazelnut superstar.
½ cup peanut butter – Smooth peanut butter works best for swirling.

Pro tip: Slightly warm the Nutella and peanut butter for 10–15 seconds in the microwave. They’ll swirl way easier.

Step-by-Step Instructions

1. Preheat the Oven

Set your oven to 350°F (175°C).
Line an 8×8-inch baking pan with parchment paper or grease it lightly. This makes removing the brownies later much easier.

2. Mix the Wet Ingredients

In a large bowl, whisk together the melted butter and sugar until smooth.
Add the eggs and vanilla extract, then whisk again until the mixture looks glossy and well combined.

3. Add the Dry Ingredients

Sift or add the flour, cocoa powder, and salt into the bowl.
Stir gently until everything combines into a thick, chocolatey batter. Don’t overmix—brownies prefer a light touch.

4. Pour the Batter

Spread the brownie batter evenly into the prepared pan.
Try not to eat the batter straight from the bowl. Or do. I’m not the boss of you.

5. Add the Nutella and Peanut Butter

Drop spoonfuls of Nutella and peanut butter randomly across the top of the batter.

6. Create the Swirl

Take a butter knife and gently drag it through the batter in swirling motions.
You’re not mixing completely—just creating pretty swirls. Less swirling = prettier brownies.

7. Bake the Brownies

Place the pan in the oven and bake for 25–30 minutes.
The center should look slightly soft but not liquid. Brownies continue to set while cooling.

8. Let Them Cool (The Hardest Part)

Allow the brownies to cool for at least 20 minutes before slicing.
Yes, waiting is painful. But cutting them too early turns them into chocolate chaos.

Common Mistakes to Avoid

Even simple brownies can go wrong if you’re not careful.

Overbaking the brownies
Nobody wants dry brownies. Check them around the 25-minute mark.
Overmixing the batter
Too much mixing makes brownies dense and tough. Stir until just combined.
Going swirl crazy
If you swirl too much, the peanut butter and Nutella blend completely instead of making pretty patterns.
Skipping parchment paper
You can skip it… But enjoy scraping brownies from the pan later.
Cutting while hot
Patience, my friend. Warm brownies crumble everywhere.

Alternatives & Substitutions

Feel like customizing the recipe? Go for it.

Use crunchy peanut butter
If you like texture, crunchy peanut butter adds a nice bite.
Add chocolate chips
Because honestly… more chocolate never hurts.
Make them gluten-free
Use a 1:1 gluten-free flour blend. Works surprisingly well.
Swap Nutella with a chocolate spread
Any chocolate hazelnut spread works fine.
Add chopped nuts
Walnuts or pecans bring extra crunch. IMO, walnuts are the best choice.

FAQ (Frequently Asked Questions)

Can I use natural peanut butter?

Yes, but stir it really well first. Natural peanut butter separates, and nobody wants oily swirl lines in their brownies.

Can I double the recipe?

Absolutely. Just bake it in a 9×13-inch pan and increase baking time slightly.

Why are my brownies dry?

You probably baked them too long. Brownies should look slightly underdone in the center when you remove them.

Can I freeze these brownies?

Yes! Wrap them tightly and freeze for up to 3 months. They thaw beautifully.

Can I add extra Nutella?

You’re asking the important questions.

Yes, you absolutely can. In fact, I encourage it.

How do I get clean brownie slices?

Let them cool completely, then cut with a warm knife. It makes perfect bakery-style squares.
