Eggless Mint Chocolate Brownies

There is something special about the combination of cool mint and rich chocolate. I love making these eggless mint chocolate brownies whenever I want a dessert that feels extra special.

They have three separate layers, starting with a rich brownie base, followed by a sweet peppermint filling and a smooth chocolate glaze on top.

Since this recipe is completely eggless, it is a great option for anyone who cannot eat eggs or simply ran out of them.

You do not have to worry about missing out on texture, because the brownies still stay fudgy and soft.

They look fancy enough for holidays and get-togethers, but you can easily make them right in your own kitchen.

Ingredient List

For the Brownies

• 1/2 cup Unsalted Butter
• 4 oz Semisweet Chocolate, Chopped
• 3/4 cup Granulated Sugar
• 1/4 cup Packed Brown Sugar
• 1/2 cup Sour Cream
• 1 tsp Vanilla Extract
• 3/4 cup All Purpose Flour
• 1/4 cup Unsweetened Cocoa Powder
• 1/4 tsp Baking Soda
• 1/4 tsp Salt

For the Mint Layer

• 1/2 cup Unsalted Butter, Softened
• 2 cups Powdered Sugar
• 2 tbsp Milk
• 1/2 tsp Peppermint Extract
• 2 drops Green Food Coloring

For the Chocolate Topping

• 3/4 cup Semisweet Chocolate Chips
• 1/3 cup Heavy Cream

Directions

Step 1

Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang on two sides.

Step 2

Melt the butter and chopped chocolate together in a large microwave-safe bowl in 30 second bursts, stirring each time. Whisk in both sugars, cool for 5 minutes, then whisk in the sour cream and vanilla until glossy.

Step 3

In a separate bowl, whisk the flour, cocoa powder, baking soda and salt. Fold into the chocolate mixture just until combined and spread evenly into the pan.

Step 4

Bake for 25 to 30 minutes, until a toothpick inserted in the center comes out with moist crumbs. Let cool completely in the pan, about 2 hours.

Step 5

For the mint layer, beat the softened butter until creamy, then add the powdered sugar, milk, peppermint extract and green food coloring. Beat for 2 to 3 minutes until fluffy.

Spread it evenly over the cooled brownies and refrigerate for 30 minutes, until the mint layer is firm to the touch.

Step 6

For the topping, heat the heavy cream until steaming, pour it over the chocolate chips and let it sit for 5 minutes. Stir until smooth, then let it cool for 10 minutes so it is lukewarm and will not melt the mint layer.

Step 7

Pour the chocolate over the chilled mint layer and gently spread it to the edges. Refrigerate for 30 to 45 minutes until set, then cut into 16 squares.

Tips

Bring the Sour Cream to Room Temperature

You will get the best results if you take your sour cream out of the fridge about 30 minutes before you start baking.

Because this is an eggless recipe, sour cream provides the moisture and structure that eggs normally supply.

If you stir cold sour cream into warm melted chocolate and butter, the chocolate will instantly seize up and become stiff or grainy.

Use Pure Peppermint Extract Instead of Mint

From my experience, you should always check the label to make sure your bottle says peppermint extract and not plain mint extract.

General mint extract usually contains spearmint, which can give your sweet frosting an unpleasant flavor like toothpaste.

Pure peppermint gives you that crisp, candy-cane flavor that pairs naturally with rich chocolate.

Let the Brownie Base Cool Completely

I recommend waiting until the baked brownie layer is cold all the way through before spreading the mint buttercream on top.

Even a tiny bit of trapped heat in the center of the pan will melt the butter in your frosting.

That will turn your creamy mint filling into a runny puddle instead of a distinct, fluffy layer.

Questions You Might Have

Can I use plain Greek yogurt instead of sour cream in the brownie base?

Yes, you can substitute full-fat plain Greek yogurt for the sour cream in a simple one-to-one swap.

Because this is an eggless recipe, the yogurt provides the necessary moisture and acidity to keep the brownies fudgy and soft.
