Strawberry Sweetheart Brownies are the dessert I make when I want something that feels both playful and a little fancy. Packed with fresh strawberries and topped with a swoon-worthy pink icing these brownies feel like a celebration in every bite whether for Valentine’s Day or just a rainy afternoon craving.
My family always asks for these every February and the strawberry aroma that fills the kitchen reminds me of spring even in the middle of winter.
Ingredients
- Unsalted butter: adds richness and a tender crumb use high-quality real butter for best flavor
- White chocolate: brings sweetness and a fudgy melt-in-your-mouth texture select quality bars over chips for smoother melting
- Sugar: balances tart strawberries and creates that signature brownie shine
- Fine sea salt: brightens flavors use a fine sea salt so it blends smoothly
- Egg and yolks: provide richness and structure make sure eggs are room temperature for easy mixing
- Strawberry purée: the star for flavor and color use ripe fresh berries for vibrancy
- Pure vanilla extract: rounds out the sweetness opt for pure not imitation for best aroma
- Pure strawberry extract: boosts the fruitiness helpful if your berries are mild
- Pink gel food color: adds a festive touch choose a gel for vivid color without watering down batter
- All-purpose flour: structure for chewy brownies always sift to avoid lumps
- Powdered sugar: gives icing a smooth finish the lighter texture makes the topping melt on your tongue
I adore using strawberry purée in both the batter and the icing it brings a cheerful natural pink that is so much prettier than anything artificial. The first time we cut these into hearts my daughter insisted on decorating them herself and now it has become a sweet ritual for us every year.
Step-by-Step Instructions
- Prepare the Pan:
- Line the base of your heart shaped pan with parchment paper and coat the sides with nonstick spray making sure every curve is covered so the brownies release cleanly
- Melt Butter and Chocolate:
- In a heat safe bowl gently melt butter and finely chopped white chocolate together either over a pan of just simmering water or in the microwave in 20 second bursts stirring after each time until silky smooth white chocolate can burn fast so take your time
- Combine Sugar and Salt:
- Stir sugar and fine sea salt into the warm butter chocolate mixture until fully dissolved creating a slightly glossy base
- Whisk in Eggs:
- Add the whole egg plus both yolks whisking until the mixture is completely smooth thick and glossy this gives the brownies their signature fudgy texture
- Prepare Strawberry Purée:
- Press your purée through a fine sieve to remove seeds then measure out two tablespoons and set aside for the icing add the rest into the brownie batter and mix until evenly distributed
- Flavor with Extracts and Color:
- Add vanilla and strawberry extracts along with that little dab of pink gel food color whisk until the color is fully even and the aroma is sweet and fruity
- Fold in Flour:
- Add sifted flour in two additions folding gently and scraping the bowl to be sure you do not miss any pockets of flour but do not overmix or brownies can become dense
- Bake:
- Spoon the batter into your prepared pan and spread it evenly bake in the center of a preheated oven at 325 F for about 25 to 30 minutes look for a toothpick emerging with a few moist crumbs that is your signal for perfectly dense brownies cool in the pan to set the crumb
- Mix Strawberry Icing:
- Whisk together powdered sugar melted butter reserved strawberry purée vanilla extract strawberry extract and a dash of salt until a thick creamy icing forms
- Decorate:
- When brownies are completely cool spread icing over the top and let it set before slicing into heart shapes or squares

Storage Tips
Store leftover brownies in an airtight container at room temperature for up to two days or refrigerate to keep a bit longer For extra freshness wrap individual brownies in plastic wrap before storing
Ingredient Substitutions
You can swap white chocolate with a high-quality white baking bar instead of chips for melting If strawberries are not in season frozen and thawed berries will also work Make sure to drain off excess liquid from thawed berries before puréeing If strawberry extract is unavailable boost the flavor with a little lemon zest or a drop more vanilla
Serving Suggestions
Heart shaped slices are perfect for special occasions or tuck one into a lunchbox as a fun treat For a plated dessert serve with a scoop of vanilla ice cream and a few fresh berries on the side For potlucks cut into squares for easy sharing and transport
Cultural and Historical Context
Brownies are an American classic but adding real fruit to the batter bridges the gap with traditional strawberry desserts like English tea cakes and Scandinavian berry bars Making them heart shaped is a nod to Valentine’s Day but in our house they are really about sharing a homemade moment
