These soft strawberry brownies with creamy frosting are an irresistibly fruity dessert that always wows at spring parties. With the convenience of cake mix and a silky homemade frosting, they are perfect for sharing or indulging when that strawberry craving hits. I love how these bars transform simple ingredients into something that feels special — every slice bursts with sweet pink flavor.
I remember baking these when I only had thirty minutes before friends came over. Everyone raved and not a crumb was left by the end of the night. The recipe is a go-to for effortless celebrations.
Gather Your Ingredients
- Strawberry cake mix: the base brings a strong fruit flavor and bright color always choose a reputable brand to avoid artificial tastes
- Eggs: add structure and richness make sure they are fresh for best rise
- Vegetable oil: keeps the brownies tender and moist use a mild oil for a clean flavor
- Vanilla extract: deepens the overall berry sweetness use pure extract for a natural aroma
- Powdered sugar: gives the frosting its light and smooth finish sift for the fluffiest result
- Butter: for creamy frosting make sure it is softened for easy blending
- Milk: to adjust frosting thickness add slowly until you reach spreadable consistency use whole or two percent for richer flavor
- Vanilla extract: a dash here also enhances the frosting flavor
- Mashed strawberries (optional): mix in for a pinker and more flavorful topping
How to Make It
- Preheat and Prep:
- Get your oven hot at three hundred fifty degrees Fahrenheit and prepare an eight by eight inch pan by greasing and lining with parchment. This helps give sharp brownie edges and easy removal.
- Mix the Batter:
- In a large bowl combine the strawberry cake mix, eggs, oil, and vanilla. Stir until well blended and thick. At first it will look crumbly but patience brings it together into a soft pink dough.
- Bake:
- Spread the dough evenly into your lined pan using a spatula to push it into the corners. Bake for twenty to twenty five minutes. The top should look set and a toothpick poked in the center will come out clean or with a few moist crumbs.
- Cool Completely:
- Rest the brownies in the pan on a rack and allow them to fully cool before frosting. If they are even a little warm the frosting will melt and slide right off.
- Make Frosting:
- Use a mixer to beat together powdered sugar, butter, milk, vanilla, and mashed strawberries if you like a more natural pink color. The mixture should be soft and spreadable not runny. Add milk drop by drop for perfect consistency.
- Frost and Slice:
- Spread the fluffy frosting all over the cooled brownies. Use an offset spatula or the back of a spoon for swirls. Refrigerate for thirty minutes if you want extra clean slices. Cut into squares and admire your pink beauties.

My favorite ingredient is the strawberry cake mix. No matter how many times I bake these my daughter always peeks into the oven just to see that gorgeous pink color. It is one of those joyful baking moments we share every time.
Flavor Boosters
Want a fruity bonus Try mixing in some mashed strawberries for a pinker and more flavorful topping. For a bolder strawberry flavor fold in a tablespoon of freeze dried strawberry powder to the frosting.
Serving Suggestions
These are wonderful with fresh sliced strawberries on top for some freshness and added beauty. For a festive look sprinkle with pastel confetti or chocolate curls. Pair with lemonade or a tangy berry sorbet for a dreamy dessert plate everyone will talk about.
Creative Twists
Feel free to play with the recipe by using raspberry or cherry cake mix instead of strawberry for a different fruity spin. Lemon zest in the frosting adds a fresh twist. Replace half the oil with applesauce for a slightly lighter treat and the result is still delicious.

Make these strawberry brownies once and they will become a go-to celebration treat in your kitchen. Their pretty color and bold flavor always bring smiles to the table.
