Fudgy, chocolate brownies are filled with York Peppermint Patties. These Peppermint Pattie Stuffed Brownies are easy, full of chocolate flavor, and perfectly minty. Step-by-step photos teach you how to make this brownie recipe.

Chocolate, Chocolate, Chocolate how I love thee. I can't seem to get enough of it. You see to me a brownie is supposed to be a dense, moist, chocolatey explosion in your mouth. I don't understand people who want a light fluffy brownie... have a piece of chocolate cake instead.
These minty chocolate brownies are perfect during the Christmas season. They definitely deserve a spot in your Christmas baking line-up! Chocolate and mint are a match made in heaven! Don't miss my Andes chocolate chip cookies.
Let's get to the recipe
Ingredients
For this minty brownie recipe you will need:
- Water. You'll just need a smaller amount, tap water is just fine.
- Unsalted Butter. I love using a combination of butter and oil, the butter flavor is beautiful but the oil provides more moisture.
- Granulated Sugar. A large amount of sugar and cooking the sugar so the granules dissolve is what helps create that classic crinkly top.
- Dutch-process Cocoa Powder. Bensdorp Dutch Cocoa Powder is my favorite
- Vegetable Oil. Using oil as the major fat in the brownies helps ensure they stay moist for days and helps create a great chewy texture.
- Pure Vanilla Extract. Vanilla pairs beautifully with chocolate. Use the real stuff, no imitation, please!
- Eggs. For this recipe, you'll need one whole egg and one additional egg yolk. The additional egg yolk provides extra moisture and fat creating a richer, fudgier, and chewier brownie.
- Baking Powder. Using just a little chemical leavening agent helps give these brownies just the right amount of lift without being cakey.
- Salt. You may be tempted to skip the salt but salt helps bring out all of the other ingredients' flavors too. As well as balance out all of the sugar.
- Cornstarch. Also known as cornflour this helps tenderize the brownies.
- All-Purpose Flour. Also known as Plain Flour.
- York Peppermint Patties. The star of the show! The thick candy is perfect for a beautiful layer inside the brownies.
Instructions
Start by preheating your oven to 350F/180C and line a 9X9 or 8X8 square pan with foil and grease with cooking spray heavily. Keep in mind brownies baked in a 9-inch square pan will bake longer than brownies baked in an 8-inch square pan.
In a large pot add the water, butter, sugar, and cocoa powder.
Cook on medium heat for 2-3 minutes until all of the ingredients are combined and butter is fully melted.
Next, add the oil and whisk to combine, the oil might not fully incorporate that is fine.
Add the egg, egg yolk, and vanilla and whisk to combine, at this point you should have one homogenous batter with no traces of egg or oil separation.
Now you can add the baking powder, salt, cornstarch, and mix to combine. Adding the other dry ingredients before the flour helps ensure you don't activate the gluten in the flour too much, that would cause a tougher brownie texture.
Gently add the flour by using a spatula to fold in until just combined, just until no flour streaks remain. Do not over mix, this will affect the end product.
Pour ½ - ⅔rds of the batter into the prepared pan, then top with 16 Peppermint Patty's in 4 rows and 4 columns.
Carefully pour the remaining batter over the chocolate candies trying to pour into an even layer using an angled spatula to gently spread the batter into an even layer to cover the candies completely.
Bake the brownies for 25-35 minutes, keep in mind =everyone’s oven is different, for me, the brownies always bake within 29-31 minutes, but I would start checking at 25 minutes for your oven Jut be careful to no overbake the brownies. You want a toothpick in the center to come out with moist crumbs, not completely dry.
Place the brownie pan on a wire rack to cool completely before cutting. Store the peppermint patty brownies an air-tight container on the counter for up to 4 days.
How to freeze
Brownies are a great candidate for freezing. Let the brownies cool completely then you can warp them individually in plastic wrap tightly then store all in a freezer-safe container. The double wrapping helps prevent freezer burn. Freeze for up to three months.
To thaw the brownies let them sit on the counter at room temperature for about an hour or so.
Can you double
You can definitely double the recipe and bake in a 9 inch X 13 inch pan and bake for 32-37 minutes or until there is no more wet batter, only moist crumsb are okay.
