Chocolate- Mint Bars

Cover recipe- Cooking Light, Chocolate- Mint Bars: March 2008

Today I’m featuring the cover recipe from an old issue of Cooking Light– March 2008.  Cooking Light doesn’t tend to put a lot of desserts on their covers, and when they do… they typically aren’t a cookie or bar type of dessert.  I’m quite often asked if I have light ideas for cookies and bars, so I can imagine that readers of Cooking Lightwould appreciate more of that sort of thing from this magazine.  Even more interesting is that this recipe was part of the Recipe Makeover series- where readers send in a favorite recipes that they’re requesting them to be lightened up.

The original recipe contained 4 eggs, loads of butter and chocolate.  The test kitchen was able to shave 6 grams of fat and 55 calories per serving off of the original recipe with their makeover.  The details on these Chocolate-Mint Bars:  A base-brownie layer is iced twice: first with a thin, sweet, and minty topping, and then with a rich chocolate glaze.

From Cooking Light: The dense base layer is like a rich, fudgy brownie, so don’t overcook it or the dessert bars will be dry. Refrigerating the mint bars allows the chocolaty top layer to set properly. You can make the dessert up to one day ahead. For a more grown-up taste, you can also use dark chocolate chips for some or all of the semisweet chocolate chips in the glaze.

Read my notes below to see what I thought of this recipe.

Chocolate- Mint Bars

Yield: 20 servings (20 pieces)

Prep Time: 35 min

Cook Time: 23 min


Bottom layer:
1 cup all-purpose flour (about 4 1/2 ounces)
1/2 teaspoon salt
1 cup granulated sugar
1/2 cup egg substitute
1/4 cup butter, melted
2 tablespoons water
1 teaspoon vanilla extract
2 large eggs, beaten
1 (16-ounce) can chocolate syrup
Cooking spray

Mint layer:
2 cups powdered sugar
1/4 cup butter, melted
2 tablespoons fat-free milk
1/2 teaspoon peppermint extract
2 drops green food coloring

3/4 cup semisweet chocolate chips
3 tablespoons butter


1. Preheat oven to 350°.
2. To prepare bottom layer: Lightly spoon flour into a dry measuring cup; level with a knife. Combine flour and salt; stir with a whisk. Combine granulated sugar, egg substitute, 1/4 cup melted butter, 2 tablespoons water, vanilla, eggs, and chocolate syrup in a medium bowl; stir until smooth. Add flour mixture to chocolate mixture, stirring until blended. Pour batter into a 13 x 9–inch baking pan coated with cooking spray. Bake at 350° for 23 minutes or until a wooden pick inserted in center comes out almost clean. Cool completely in pan on a wire rack.
3. To prepare mint layer:  Combine powdered sugar, 1/4 cup melted butter, and next 3 ingredients (through food coloring) in a medium bowl; beat with a mixer until smooth. Spread mint mixture over cooled cake.
4. To prepare the glaze: Combine the chocolate chips and 3 tablespoons butter in a medium microwave-safe bowl. Microwave at HIGH 1 minute or until melted, stirring after 30 seconds. Let stand 2 minutes. Spread chocolate mixture evenly over top. Cover and refrigerate until ready to serve. Cut into 20 pieces.


*The Hershey's syrup is by weight, not fluid ounces. So, if you're pouring from a bottle, weigh it, don't measure.
*Don't expect a fudgy brownie layer. Cooking Light claims that it's fudgy... it's very moist, but I found it to have more of a velvety/cakey texture than fudgy.
*Leave out the food coloring if you wish. I personally like to include it as it gives eaters a 'hint' that there is mint-flavor tucked within.
*Watch the baking time. Mine had to bake up slightly longer than 23 minutes. At 23 minutes they appeared a little too gooey.
*The frosting layer is pretty liquidy at first- best to get it onto the cooled brownie layer, then refrigerate it before adding the chocolate layer.
*I had a some good-quality dark chocolate lying around so I chopped that up and used it for the top layer.
*They're good cold.
*If you're pulling them out of the refrigerator, it's best to let them sit on the counter for about a half hour to warm up the layers. When I tried to slice into the bars when the layers were very cold, the chocolate layer on top wanted to crack. When left at room temperature a while, it softened up a bit. I used a thin, sharp knife to cut and didn't have any trouble with cracks.

The results:

I thought these bars were fabulous.  They’re light in texture and I loved the chocolate-mint combination- kind of like the Girl Scout Thin Mint Cookies in the form of a brownie.

Did this recipe deserve the cover spotlight?

Yes! I loved that they featured a dessert bar on their cover. I thought it was a fun recipe to feature in March for St. Patrick’s Day (alternative to the usual St. Paddy’s Day fare). And these were delicious!

    Yum! I would hope for a fudgier brownie but even so these sound terrific. I made a recipe similar to this back in January. Dare I say they were my favorite brownies ever?

    One of my favorite things that my mom makes is a chocolate mint bar… that’s exactly like this.

    I just read your note that said that they’re good cold… YES! We always kept them in the freezer. It’s so much better that way.

    Oh, I’m so craving chocolate and mint right now. Have something planned for next week, but it’s not light….and it SHOULD be; I’m *trying* to be good! ;) Darn those WW points!

    Happy St. Patrick’s Day, Lori!

    I’ve been making a non light version of these for holiday gift baskets for yeasr. I’m anxious to try these and see the difference.

    One thing; that top layer used to be a problem until I started using a warm knife. Dip your knife into very hot water before slicing the squares, it should help to keep it from cracking without having to let the dessert warm up.

    I call them Frango Mint Bars. They are one of my must bake Christmas bars.
    I’ve been making these for at least 20 years. Don’t remember where the recipe came from but they are a seasonal favorite of mine. I do make them on special occasions When asked. Everyone should have this recipe in their recipe box.
