These Pistachio Brownies are dense and deeply fudgy, with a rich cocoa base and pockets of melted chocolate throughout. Pistachio cream is swirled into the batter, (twice!) adding an extra layer of nutty depth and a soft, creamy contrast.

First it is important to mention that this is not a recipe for the light-hearted. These brownies are extra rich, extra dense, melt-in-the-mouth pistachio indulgence. Three types of chocolate along with two types of pistachios and a generous portion of sugar makes this a lavish, yet decadent treat. It’s a combination between these fudgy Black Forest Cupcakes, and these swirled Biscoff Brownies.
The Ingredients
The full recipe including measurements is at the bottom of this post in the recipe card. Here is a quick look at the key ingredients including substitutions in needed:
- Chocolate. Dark chopped chocolate, natural cocoa powder, and milk chocolate chips, each has a key rule in the flavor and texture of the recipe. . I like how milk chocolate enhances the pistachios’ flavor but it also adds another layer of sweetness so If you want to reduce the sweetness replace the milk chocolate chips with semi-sweet, or reduce it by half.
- Pistachio Cream. You can use a homemade recipe or store bough, but it should be soft enough to be swirled into the batter easily. If it is too thick, warm it for 15-20 seconds. Or, mix it with 2 Tablespoons of the batter with the first porting of the cream.
- Chopped Pistachios. It does hide the beautiful pistachio swirl, but it adds a crisp texture and slight saltness to balance all the sweets. Use roasted and salted pisatchios.
Make It
You only need a large bow, the recipe is pretty straightforward, and the best way to succeed, it to measure the ingredients ahead of time. Here are some more tips :
- You can melt the butter and chocolate using the microwave, or a double boiler.
- When incorporating the pistachio cream, fold it in only three times and not all the way, the cream is sweet and the idea is to avoid incorporating it fully into the batter.
- Pay attention to the brownie and not the timer. Your oven is different than mine and you may need longer, or shorter baking time. The brownies are ready when a toothpicks comes out of the center of the pan with some moist crumbs. If it comes out with smooth dark batter, it is not ready. If it comes out with crumbs and some batter, than it is ready.
- When out of the oven, the brownies are not fully baked, and need some time to “bake” and set from the heat residue. Do not slice it or try to remove from the pan, it will break.
