There’s a heart-warming story behind this stack of Sugar-Free Whole Wheat Brownies. A few weeks ago my sister Pam’s mother-in-law passed away. When I went to the viewing for Grandma Willey there was a table of memories of her life, along with a stack of printed recipe cards and a little sign that said “Dorothy’s favorite recipe, please take one.”  On the card was the recipe for Dot’s Brownies.

Grandma Willey wasn’t technically a relative of mine, but I did see her often at Willey family events and always enjoyed her warm personality, her forthright comments, and her political philosophies, including a strong belief in women’s rights. The last few years of her life she suffered with poor eyesight, and I admired the way Pam’s husband Kelly and his sister Elizabeth took care of their mom’s every need.

I’m pretty sure Grandma Willey didn’t use a computer and I’m not sure if she even knew about my blog, but I thought it would be fun come up with a recipe for sugar-free and whole wheat brownies were adapted from her brownie recipe. This not a super-sweet brownie the way I’ve made it, which suits my tastebuds perfectly. I’ll always remember Grandma Willey mostly for the goodness she instilled in her son Kelly, who has done so many nice things for me during my life, but now I have a great brownie recipe to remember her by as well.

What ingredient do you need for this recipe?

How did I change Grandma Willey’s recipe?

Grandma Willey’s brownies had frosting, something I skipped for a sugar-free version. And when I tried the recipe the first time just substituting sweetener for sugar, I thought they were not quite sweet enough, so the version I’m sharing here has an extra 1/2 cup of sweetener. Grandma Willey used margarine (probably this was a depression-era recipe) but I made my version with butter the best; use margarine or coconut oil if you prefer. I also switched the white flour for white whole wheat, something I use in almost all my baking recipes that have flour.

How to Make Sugar-Free Whole Wheat Brownies:

(Scroll down for complete recipe with nutritional information.)

  1. Use the microwave to melt the butter or oil/margarine of your choice in a bowl that’s big enough to hold all the ingredients.
  2. Mix 7 tablespoons of cocoa powder into the melted butter.
  3. In a smaller bowl, beat 4 eggs with Monkfruit Sweetener or other sweetener of your choice. 
  4. Mix the egg mixture into the cocoa powder mixture.
  5. Then add the flour, salt, and vanilla and stir to combine.
  6. I loved the part of the recipe that said 1 cup nuts (hand broken) and I did indeed break them by hand.
  7. Press the mixture into a sprayed baking dish. I used a glass dish that was about 8″ x 11″ which gave me twelve large brownies.
  8. Bake at 350F/180C for 30 minutes, and then let the brownies cool in the pan for a few minutes before cutting.

Sugar-Free Whole Wheat Brownies with Walnuts are a healthier version of Grandma Willey's famous brownies.


  • 1 cup melted butter (see notes)
  • 7 T cocoa powder
  • 4 eggs, well beaten
  • 2 1/2 cups Monkfruit Sweetener (see notes)
  • 1 1/3 cups white whole wheat flour
  • pinch of salt
  • 2 tsp. vanilla
  • 1 cup walnuts (hand broken)


  1. Preheat oven to 350F/180C.
  2. Use a microwave to melt the butter or other fat choice in a large bowl (big enough to hold all the ingredients.)
  3. Stir the cocoa powder into the melted butter.
  4. In a separate small bowl, beat the eggs well, then stir in 2 1/2 cups Golden Monkfruit Sweetener (affiliate link) or whatever sweetener you prefer) and stir again.
  5. Stir the egg mixture into the cocoa mixture.
  6. Then add the flour, salt, and vanilla and stir to combine.
  7. Use your fingers to break enough walnuts to make 1 cup, and then gently stir them into the batter.
  8. Spray a glass baking dish with nonstick spray and then add the batter, pressing down so the brownies are evenly flat.  (I used a dish that was about 8″ x 11″.)
  9. Bake 30 minutes, then let the brownies cool in the pan for 10-15 minutes before cutting.


If you don't have butter you can use margarine or coconut oil; do not use margarine that has water as the first ingredient.

I'm a huge fan of Lakanto Monkfruit Sweetener (affiliate link) but use another sweetener or brown sugar if you prefer.
