The brownies are lighter than normal brownies, but they still taste amazing.

Spring can be a busy time in my house. My gardens are calling out to me to get out there and get them ready for spring, and Easter gave me lots of opportunities to try out new recipes and activities.

With all the things that I need to do, taking a break and having a sweet reward is high on the top of my list. Is it like that at your house, too?

These low calorie brownies are fast and easy to make.

I chose Diet Dr. Pepper because I love the way it tastes as a drink, and also because I like to use it when I make brownies. Yup…that’s right.

The brownies can also be made with diet coke. The taste will vary slightly but the texture and calories will be the same.

I love using diet soda in my brownie recipe, because it cuts out the need for oil. A cup of oil has 1910 calories and a bottle of diet soda has zero.

Do the math and you’ll see the calorie savings!

I also only use an egg white and not the whole egg to keep the calories down too. This makes my sweet reward a slimmed down one too!Floer, with water, egg white, Diet Dr Pepper bottles, and silicone tools

If you have never made a brownie or dessert with soda before, keep in mind the texture will be different. This is not a cakey brownie.

It has a much lighter texture, since it has no oil and omits the yolk of the egg, but still tastes delicious. I make them when I am trying to watch my weight but still want a sweet reward.

They have a cake like bottom and a much lighter top to them.Brownie batter in a bowl with a blue whisk and brownie batter in a pan photos made into a collage.

The slimmed down brownies are simple to make. All you need is any boxed brownie mix, 10 ounces of Diet Dr. Pepper and an egg white.

Just mix them all together and place in a glass pan and bake for about a half hour.

Garnish the low calorie brownies with some whip cream and a cherry and serve with a glass of Diet Dr. Pepper for a really sweet reward. Brownie on a checked plate with whip cream and a cherry, near a plate of Diet Dr Pepper brownies.

Time for me to head out to the garden with my low calorie brownies sweet reward for a bit of me time!

I would never have thought of putting Dr. Pepper into a brownie or cake. But I imagine it would be delicious!

It gives just a hint of the soda in the brownie. I loved them.
