3-Ingredient Strawberry Brownies Recipe

With spring and summer around the corner, we’re gearing up to make all of our summer berry desserts! If you love all things strawberry and no fuss-baking, these heavenly brownies have to be added to your must-try summer baking list.

We are adjusting the amount of oil and eggs used in the cake mix so that they turn out perfectly gooey and decadent, just as brownies should be. The striking pink color elevates them making them impressive and elegant. No one needs to know how easy they are to make!

They’re perfect for wedding showers, baby showers, and garden parties but easy enough to whip up for pool parties and casual after-dinner desserts!

Why You’ll Love Strawberry Cake Mix Brownies

  • Delicious. A dessert that showcases the flavor of strawberry front and center! One bite into that fudgy bar and you’re hooked. 
  • Simple. Only 3 ingredients and one of them is a cake box mix! Strawberry sheet cake and strawberry cake mix cookies are two more cake mix recipes you’ll love!
  • Adaptable. I love a good shortcut recipe that’s adaptable to any cake mix flavor.

Cake Batter vs Brownie Batter

What exactly is the difference? The answer lies in the extra ingredients! Cake batter uses a leavening agent which helps it rise and become nice and fluffy. Brownies generally use much less. 

In this case, we are using a cake mix, but adding in more eggs and oil than the box mix calls for. This helps counteract the rise and makes it nice and fudgy. It’s not a classic brownie recipe but it looks and tastes like it is!

Ingredients for Strawberry Brownies

  1. Strawberry cake mix: No particular brand, just whatever you can find in your local grocery store. 
  2. Vegetable oil: The fat needed to create a moist, gooey consistency. 
  3. Large eggs: Needed for structure but also added moisture for great texture. 

Sweet Strawberry Glaze

The strawberry glaze takes these brownies over the top. Below are the ingredients needed to make it.

  • Powdered sugar: The sweet sugary component that dissolves nicely into a smooth glaze.
  • Strawberry jam: No better way to showcase fresh strawberries than in a homemade strawberry jam (store bought works great too).
  • Heavy cream: The liquid component that when added to the powdered sugar takes it from a powder to a paste. Then to a glaze. 
  • Fine sea salt: Just a pinch to enhance all of the surrounding flavors and to balance the sweetness.

How to Make Strawberry Brownies

Just 2 easy steps to make the brownies, but when topped with a homemade strawberry glaze they become even more irresistible. It’s worth the extra couple of steps!

  1. Mix strawberry cake mix. Combine the box of cake mix, oil, and eggs in a large bowl. Stir until combined. It will be a thicker mixture than an average cake batter. 
  2. Bake brownies. Pour brownie batter into an 8×8 square baking pan lined with parchment paper and press it down with the palm of your hands. Bake in a preheated 350-degree oven for 18-20 minutes or until a toothpick comes out clean. Allow it to cool before adding the glaze.
  3. Make the glaze. Whisk together the powdered sugar, jam, heavy cream, and salt until smooth. Add more cream or milk as needed to thin it out. 
  4. Spread glaze on top. Once strawberry brownies have cooled, spread the frosting over top and slice into 16 bars. 

Recipe Tips

  • Prepared pan. Using parchment paper is great for providing a nonstick surface and easy removal of the strawberry brownies. If you don’t have any, be sure to use melted butter or a cooking spray instead.
  • Easy mixing. A hand mixer isn’t necessary but will speed up the mixing process as this will be a thick batter and harder to mix than a regular cake batter.
  • The glaze should be the consistency of glue. Not too thick and not too thin. 
  • Cool your strawberry brownies before adding the layer of frosting, otherwise, it will melt and become too runny.

Variations & Fun Add-Ins

  • White chocolate chips. Mix in 1/2 cup white chocolate chips for a little extra sweetness and texture. The sprinkling of white chocolate throughout looks fantastic!
  • Omit the glaze if preferred, they are terrific all on their own and a little less sweet that way.
  • A different cake mix. Use this recipe for any flavor of brownies you’d like. Just switch up the flavor of the cake mix to whatever you like. Chocolate brownies are always classic!
  • Freeze-dried strawberries. To give these strawberries even more strawberry love, throw in some freeze-dried strawberries into the brownie mix. Avoid using fresh strawberries in the batter because the water content will throw off the consistency. Save them for garnish on top!

Frequently Asked Questions

How do I know when my brownies are done?

If you’re following the instructions as listed, then you should be just fine keeping them in there for 18 – 20 minutes. Check at the 18-minute mark, using a toothpick. Insert it in the middle of the brownie dish and if it comes back out clean, it’s ready. If not, leave it for the remaining 2 minutes.

Do strawberry brownies need to be refrigerated?

They don’t! You can keep them at room temperature, as long as they are covered in an airtight container, for up to 3 days. If you want to stretch it out for a few more days, pop them into the fridge. 

Can I store these strawberry brownies in the freezer?

Please do! They’re a great dessert to have on hand last minute. Transfer your brownies to a freezer-friendly bag. Separate the layers with parchment paper so they don’t freeze in a clump. Thaw them in the fridge overnight or just leave them on the counter for a couple of hours.
