    This low sugar chocolate cake would go great with our low sugar cream cheese frosting or our low sugar ice cream recipe. 

    We love desserts around here, but we like to make them with less sugar. We find ourselves reducing the sugar in almost all the recipes we make. They just don’t need to be that sweet. We still like them to taste sweet, just not too sweet.

    Chocolate and whole wheat flour are like a match made in heaven. Chocolate pairs well with the flavor of whole wheat, but it also has a way of making the texture seem like all purpose flour baked goods. If you’re new to using whole wheat then making chocolate desserts is a good place to start.

    What's Cool About This Recipe

    • 100% whole grain: This cake is made with whole wheat flour making it healthier than traditional cake.
    • Low sugar: We took a classic chocolate cake recipe and reduced the sugar a bit to make this low sugar chocolate cake.
    • Small batch: Like our banana cake, this recipe makes the perfect amount of cake batter to fill two 6 inch round cake pans for 2 layers about ¾ inch thick. You can double the recipe if you want a bigger cake.

    Ingredients and Substitutions

    Ingredients for healthier chocolate cake in original containers on a tray.
    • Flour: Flours that work for this cake
      • Fresh milled soft white wheat, highly recommended as it makes the very best cake
      • Whole wheat pastry flour (store bought), this makes a good cake but not as good as fresh milled flour
      • Fresh milled hard white wheat
      • Whole spelt flour
      • High extraction whole wheat flour like this one from Living Sky Grains
    • Unsweetened cocoa powder: Don’t use dutched (alkaline) cocoa. You need the acidity from regular cocoa powder to activate the baking soda.
    • Baking soda
    • Baking powder
    • Salt 
    • Oil: We usually use avocado oil or olive oil, any oil you use for baking should do.
    • Sugar: We use organic granulated cane sugar, you can also use coconut sugar.
    • Egg
    • Vanilla extract
    • Hot water

    See recipe card for quantities.

    To Make Cupcakes

    Divide the cake batter evenly between 6-7 paper lined cupcake cups.

    Bake at 350° F for 16-20 minutes or until a toothpick inserted into the center of a cupcake comes out with a few moist crumbs. Or just visit our chocolate cupcake recipe

    Frosting for Chocolate Cake and Cupcakes

    We recommend frosting this cake with your favorite frosting. We love putting a layer of fruit or pudding filling in the middle and then frosting with something yummy like:

    • Cream cheese frosting 
    • Whipped cream cheese ganache
    • Dark chocolate frosting
    • Or a simple whipped cream frosting
    • Espresso Whipped Cream Frosting

    Serving Suggestions

    The obvious way to eat cake is to frost it, slice and serve, but there are other ways to serve it. You can:

    • Make parfaits, cut the cake into small squares then layer in individual cups with pudding, fruit and whipped cream.
    • Serve slices with fresh fruit and ice cream on top.
    • Or with ice cream, caramel sauce, fudge sauce and toasted pecans.
    • Make cake pops

    Storage

    If the cake is frosted it will probably need to be stored in the refrigerator. It will last 3-4 days.

    How to Freeze

    To freeze the cake layers wrap them tightly in several layers of plastic wrap and additionally in tin foil if you want. They will last for 2-3 months. Remove the wrapping, and cover to thaw. Frost or eat soon after they are thawed to prevent them from drying out.

    Tips From Our Kitchen

    Use an electric hand mixer, or whisk vigorously for about 30 seconds. Whole wheat flour cakes are different from cakes made with all purpose flour, if you don’t stir the batter enough they can be crumbly. 

    For best results we recommend using freshly milled/ground flour, the results you get from fresh flour are astounding, and sooo much better than store bought whole wheat flours.

    Double the recipe for a 2 layer, 9 inch cake.

    FAQ

    Why is my cake dense?

    A dense cake can be caused by using too much flour. Make sure you measure precisely or use a kitchen scale for the most accurate measurements.

    Why is my cake crumbly? 

    Crumbly whole wheat cake can be because you didn’t mix the batter enough, I know, it sounds counterintuitive. But the bran in whole wheat flour is sharp and acts like little razors cutting the gluten strands. So mixing the batter a little extra helps activate the gluten, giving it a greater chance of survival among its bran enemies. 

    Why did my cake fall?

    Make sure your oven is completely up to temperature before putting your cake in the oven. Do not open the oven door while the cake is baking (until it’s time to check for doneness). 
    If the floor of your home is not very stable then be careful walking around your kitchen while the cake is baking.

    We were having a lot of problems with our cakes falling and then we discovered that our oven temperature was fluctuating quite drastically.

      Is wholewheat pastry flour the same as wholewheat flour? I live in Zambia and wholewheat pastry flour isn’t anything I’ve seen in the shops but we do get what’s labelled as “wholewheat flour”. Thank you 🙂 x

        No, it is not the same. Whole wheat pastry flour is ground from soft white wheat and is a less heavy flour. Whole wheat flour is usually ground from hard red wheat and usually makes more dense baked goods.
