Ingredients

1/2 cup chopped chocolate pieces
1 cup non-dairy Greek yogurt
1/2 cup sweetener of choice (sugar-free, white or brown sugar)
3/4 cup regular or gluten-free all-purpose flour
1/2 cup cocoa powder
1/2 teaspoon baking soda
1/2 cup preferred milk (like unsweetened almond milk)
1 cup optional chocolate chips

Instructions

Step 1: Preheat your oven to 180°C (350°F). Line an 8 x 8-inch baking pan with parchment paper, leaving some overhang for easy removal. Set the pan aside.
Step 2: Place the chopped chocolate pieces in a microwave-safe bowl. Melt in short 20-second bursts, stirring in between until smooth. Let cool for 1-2 minutes, then whisk in Greek yogurt and sweetener until smooth. Transfer this mixture to a large mixing bowl.
Step 3: Add the flour, cocoa powder, and baking soda to the chocolate mixture. Stir gently until just combined without overmixing. Pour in the milk and mix until fully incorporated. Fold in chocolate chips if using.
Step 4: Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 25-30 minutes, checking at 25 minutes by inserting a toothpick in the center—it should come out with moist crumbs, not wet batter.
Step 5: Remove the brownies from the oven and let them cool in the pan for about 10 minutes. Use the parchment overhang to lift the brownies out and transfer them to a wire rack to cool completely before slicing.

Tips & Variations

For a moist texture, use whole milk Greek yogurt or thick non-dairy Greek-style yogurt that is unsweetened.
Try replacing Greek yogurt with silken tofu or mashed banana for different flavors and textures.
Swap the sweetener for monk fruit, stevia, or erythritol, adjusting amounts as needed.
Use a gluten-free flour blend or almond flour (reduce to 2/3 cup) for gluten-free brownies.
Add cacao nibs or chopped nuts instead of chocolate chips for variety.
Don’t overbake—start testing brownies at 25 minutes to keep them fudgy.

Storage

Store these brownies in an airtight container at room temperature for up to 5 days. In warmer climates, refrigerate them to keep fresh for up to a week. For longer storage, freeze individually wrapped brownies in a freezer bag for up to 3 months. Thaw at room temperature for about an hour before serving, or warm for 10-15 seconds in the microwave for a fresh-baked taste.

How to Serve

Three thick, square chocolate brownies are stacked one on top of the other. Each brownie has a rich, dark brown color with a slightly cracked top, showing a moist, dense, and fudgy texture inside. The edges of the brownies are firm and slightly crumbly, while the middle looks soft and smooth. The stack sits on a piece of white parchment paper on a white marbled surface, with a soft light coming from the back, highlighting the shiny crust on top. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Why is my brownie batter thicker than usual?

Greek yogurt makes the batter thicker compared to traditional recipes that use oil or butter. This thicker batter helps create the dense, fudgy texture characteristic of these brownies.

Do I need to let the brownies cool completely?

Yes, letting the brownies cool completely is important. They need extra cooling time due to the Greek yogurt and will continue to set as they cool, giving you clean slices and the perfect texture.
