Ingredients
- 1/2 cup chopped chocolate pieces
- 1 cup vanilla-flavored Greek yogurt (*see notes)
- 1/2 cup sweetener of choice (white, brown sugar alternative, or blend)
- 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 (unsweetened almond milk, oat milk, dairy milk, etc.)
- 1 cup optional chocolate chips (sugar-free or regular)
Step-by-Step Instructions
- Preheat your oven to 350°F (175°C). Grease or line an 8×8-inch baking dish with parchment paper.
- In a microwave-safe bowl, melt the chopped chocolate pieces in 20–30 second bursts, stirring in between until smooth. Set aside to cool slightly.
- In a large mixing bowl, whisk together the Greek yogurt and sweetener until well combined.
- Add the melted chocolate to the yogurt mixture and stir until smooth.
- Sift in the flour, cocoa powder, and baking soda. Mix gently until just combined — avoid overmixing.
- Pour in the milk and fold until a thick batter forms. If using chocolate chips, fold them in at this stage.
- Transfer the batter to the prepared baking dish and spread evenly.
- Bake for 20–25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
- Allow brownies to cool completely before slicing for the best texture.
Recipe Notes
- Sweetener: Monk fruit, erythritol, stevia blends, or allulose work well. Adjust to taste.
- Greek Yogurt: Use unsweetened vanilla-flavored Greek yogurt for better control over sweetness. For dairy-free, use coconut yogurt.
- Flour: Gluten-free 1:1 baking blends work just as well as regular all-purpose flour.
- Texture Tip: For fudgier brownies, slightly underbake and allow them to firm up as they cool.
