Peanut Butter and Chocolate Flourless Brownies

The Fudgiest Flourless Brownies — No flour, no problem! Chocolate and peanut butter are all you need for super fudgy flourless brownies!

Gluten-Free Chocolate Brownies with Peanut Butter

These are the fudgiest brownies I’ve ever made. That’s what happens when there’s no flour.

And there’s no flour replacers, black beans, avocado, or any ‘interesting’ ingredients. Ahem.

Lately when I see flourless brownie recipes on the web, it’s a safe bet that there’s beans in them. I love beans, but I’ll keep them in my slow-cooker and out of my brownies. Thanks.

The flourless brownies are made with just a few simple ingredients. Chocolate, peanut butter, sugar, eggs. Now we’re talking.

They taste elegant, classy, and fancy, but take just minutes to make and you don’t even need a mixer.

They’re rich, velvety smooth, and not overly sweet. They’re what you crave on certain days when nothing else will do.

The peanut butter flavor is present yet subtle in the brownies themselves. However, I played up the peanut butter aspect by drizzling them with peanut butter. Going hog wild with my squirt bottle was almost as satisfying as the brownies.

The interesting thing about them is that although they’re very fudgy and not at all cakey, they’re not dense or too thick. 

They’re perfect for anyone who’s gluten-free since they’re inherently gluten-free.

And they’re perfect for anyone who loves chocolate and peanut butter, which is everyone, right?

Ingredients in Flourless Brownies

To make these gluten-free peanut butter chocolate brownies, you’ll need the following easy-to-find ingredients: 

• Unsalted butter
• Semisweet chocolate chips
• Creamy peanut butter
• Brewed coffee
• Eggs
• Granulated sugar
• Vanilla extract
• Cocoa powder
• Instant espresso granules 

Can a Different Nut Butter Be Used? 

Of course! You may use any nut butter you’d like for this flourless brownie recipe, noting that no-stir or “traditional” nut butters work best. 

For more of a true chocolate brownie flavor, try using cashew butter or sunflower seed butter. They’re milder in flavor than peanut butter. 

Can the Coffee Be Omitted? 

There’s two tablespoons of coffee and 1 teaspoon of instant espresso granules in the batter. Both serve to intensity and round out the chocolate flavor, but don’t make the brownies taste like coffee.

Although you could use water instead of coffee and skip the espresso, I wouldn’t.

How to Make Flourless Brownies

Making these no-flour peanut butter fudge brownies is simple! Here are the basic steps: 

1. In a large microwave-safe bowl, add the butter and heat for 1 minute on high power to melt.
2. Add 2 cups chocolate chips, one heaping 1/2 peanut butter, coffee, and heat for 1 minute on high power to melt.
3. Whisk mixture until smooth.
4. Add the eggs, sugar, vanilla, and whisk until smooth.
5. Add the cocoa powder, espresso granules, and whisk until smooth.
6. Turn batter out into a foil-lined 9×9-inch pan.
7. Bake until the edges are set, and the top and center have just set and are not jiggly.
8. Place pan on a wire rack and allow brownies to cool completely before adding the PB drizzle. 

Can This Recipe Be Doubled? 

Yes, very easily! Simply double the ingredients and bake in a 9×13-inch pan. The bake time should remain roughly the same. 

Can Mix-Ins Be Added? 

I imagine so! Just be sure to use gluten-free mix-ins if you need to keep this chocolate brownie recipe gluten-free. 

Tips for Making Brownies Without Flour

“Traditional” no-stir peanut butter from a brand like Jif or Skippy will work best in this recipe. Homemade peanut butter will also work, but the brownies might be slightly oilier. 

A few readers have asked whether the eggs / butter / sugar can be substituted, and for all of those ingredients, my answer is maybe. I don’t typically make low-carb or dairy-free desserts, so I really can’t speak to the best substitutes. 

I recommend serving the flourless brownies chilled because anything this dark and fudgy tastes better chilled.

Instructions 

Make the brownies:

• Preheat oven to 300F.  Line a 9×9-inch pan with foil, spray with cooking spray; set aside.
• In a large microwave-safe bowl, add the butter and heat for 1 minute on high power to melt. It’s okay if it hasn’t melted after 1 minute.
• Add 2 cups chocolate chips,a heaping 1/2 cup peanut butter, coffee (doesn’t make the brownies taste like coffee and serves to enhance and bring out the chocolate flavor), and heat for 1 minute on high power to melt.
• Whisk mixture until smooth. If necessary, heat in 10-second bursts until mixture can be whisked smooth.
• Add the eggs, sugar, vanilla, and whisk until smooth.
• Add the cocoa, optional espresso granules, and whisk until smooth.
• Turn batter out into prepared pan, smoothing the top lightly with a spatula.
• Bake for about 35 minutes or until edges are set, and the top and center have just set and are not jiggly. A toothpick inserted in the center should come out with a few moist crumbs, but no batter.
• Place pan on a wire rack and allow brownies to cool completely, at least 2 hours, before adding the drizzles. If you add the drizzles to warm brownies, they’ll melt together and while it tastes the same, cosmetically it isn’t what’s shown.

Make the drizzle:

• After brownies have cooled, add 1/2 cup chocolate chips to a small microwave-safe bowl and heat on high power to melt, about 1 minute. Stir until smooth and drizzle over brownies using a spoon or squirt bottle; set aside.
• Add 1/3 cup peanut butter to a small microwave-safe bowl and heat on high power to melt, about 45 seconds. Drizzle over brownies using a spoon or squirt bottle.
• I recommend chilling the brownies before serving because they’re rich, bold, and taste better when chilled. Cover pan with a sheet of foil to prevent fridge smells and chill brownies for at least 4 hours, or overnight, before serving.

Notes

Storage: Brownies will keep airtight in the refrigerator for up to 7 days.
