Ingredients

Main Brownie Ingredients

  • 11/2 cups dark chocolate chips (53% cacao, divided)
  • 1/4 cup + 2 tablespoons coconut oil
  • 1 cup honey vanilla Greek yogurt
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking soda
  • 1/2 cup coconut sugar (or light brown sugar)
  • 3/4 cup oat flour (made by blending regular oats)
  • 1/2 cup dark chocolate chips

Optional Frosting Ingredients

  • 2 tablespoons unsweetened vanilla almond milk (or any milk)
  • 2 tablespoons vanilla Greek yogurt
  • 3/4 cup powdered sugar

Instructions

  1. Prepare: Preheat your oven to 350°F (176°C). Line an 8×8-inch baking pan with parchment paper, making sure to leave an overhang for easy removal later. Lightly spray the parchment with cooking spray to prevent sticking.
  2. Melt Chocolate: Place 1 cup of the dark chocolate chips in a large mixing bowl. Melt the 1/4 cup plus 2 tablespoons of coconut oil in a microwave-safe bowl until hot. Pour the melted coconut oil over the chocolate chips and stir until smooth. If the chocolate hasn’t fully melted, microwave in 10–15 second increments, stirring after each, until completely melted and smooth. Allow to cool slightly.
  3. Add Remaining Ingredients: Whisk the honey vanilla Greek yogurt into the melted chocolate mixture. Then add the vanilla extract, salt, baking soda, and coconut sugar. Whisk everything together until the batter is completely smooth.
  4. Blend Oats: Blend regular oats in a blender until they form a fine powder to make oat flour. Measure out 3/4 cup of this oat flour and stir it into the batter along with the remaining 1/2 cup of dark chocolate chips.
  5. Bake: Spread the thick batter evenly into the prepared baking pan. Bake for 28 to 32 minutes, or until a fork inserted into the center comes out clean. Be careful not to overbake; slightly underbaking will yield a fudgier brownie. Once done, let the brownies cool completely in the pan placed on a wire rack.
  6. Make Optional Frosting: For the frosting, combine the remaining chocolate chips and unsweetened vanilla almond milk in a microwave-safe bowl. Microwave in 15-second bursts, stirring each time, until smooth. Stir in the vanilla Greek yogurt, then whisk in the powdered sugar. Whisk briskly until the frosting is completely smooth. Let it sit at room temperature for 10 minutes to thicken before spreading it over the cooled brownies.
  7. Chill: Cover the pan with the brownies and refrigerate for at least 6 hours or overnight. These brownies are best served cold for the perfect texture. Once chilled, use the parchment paper overhang to lift the brownies out of the pan and cut into 16 squares.

Notes

  • Use high-quality dark chocolate chips with at least 53% cacao for a rich flavor.
  • Coconut oil adds healthy fats and aids in melting the chocolate smoothly.
  • Honey vanilla Greek yogurt contributes moisture and a slight sweetness while keeping the brownie healthier.
  • Blending oats into flour is an easy gluten-free alternative for texture and nutrition.
  • Avoid overbaking to keep brownies moist and fudgy.
  • The frosting is optional but adds a creamy, sweet finish that balances the bittersweet chocolate.
  • Chilling the brownies enhances firmness and flavor—best enjoyed cold.
