Essential Ingredients
Here’s what you’ll need to make this delicious dish:
Fresh Rhubarb: Look for crisp, firm stalks that are bright in color; avoid wilted ones for the best flavor.
Unsweetened Cocoa Powder: Choose high-quality cocoa powder to ensure deep chocolate flavor that complements the rhubarb perfectly.
Granulated Sugar: Regular sugar works well here; it helps balance the tartness of rhubarb beautifully.
All-Purpose Flour: Use standard flour for structure; if gluten-free is needed, substitutions can work too!
Butter: Unsalted butter gives you better control over saltiness; melt it gently for a smoother batter.
Eggs: Fresh eggs bind everything together and add richness; room temperature eggs mix more easily.
Vanilla Extract: Opt for pure vanilla extract for the best flavor; imitation just won’t do these brownies justice.
Salt: A pinch enhances all flavors; don’t skip it!

How to Make Chocolate Rhubarb Brownies
Preheat Your Oven and Prepare Your Pan: Start by preheating your oven to 350°F (175°C). Grease an 8×8 inch baking pan with non-stick spray or line it with parchment paper for easy removal.
Combine Dry Ingredients: In a bowl, whisk together flour, cocoa powder, and salt until evenly mixed. This step ensures no lumps ruin your chocolate dream!
Melt Butter and Mix with Sugar: In a saucepan over low heat, melt the butter until just bubbling. Remove from heat and stir in granulated sugar until well combined and slightly cooled.
Add Eggs and Vanilla Extract: Beat in the eggs one at a time into the butter mixture until smooth. Stir in vanilla extract for an aromatic boost that pairs perfectly with chocolate.
Fold in Dry Ingredients and Rhubarb: Gradually fold the dry ingredients into the wet mixture using a spatula. Gently fold in diced rhubarb until evenly distributed throughout the batter—this is where magic happens!
Bake to Perfection: Pour your luscious batter into the prepared pan and smooth out evenly. Bake for 25-30 minutes until a toothpick inserted comes out with moist crumbs but not wet batter—trust me on this!
Now you have your delectable Chocolate Rhubarb Brownies ready to cool before slicing them up! Enjoy them warm or at room temperature—good luck resisting!
