Ingredients
For the Brownies:
• 2 eggs
• 3 ripe bananas, mashed
• 1½ cups granulated sugar
• 1 cup sour cream
• ½ cup unsalted butter, softened
• 2 tsp vanilla extract
• 2 cups all-purpose flour
• 1 tsp baking soda
• ½ tsp salt
• ½ cup chopped walnuts (optional)
For the Frosting:
• ½ cup unsalted butter
• 3 cups powdered sugar
• 1½ tsp vanilla extract
• 2–3 tbsp milk (adjust for consistency)
Instructions
1️⃣ Make the Batter:
Preheat oven to 350°F (175°C). Grease a 9×13-inch pan. In a large bowl, cream butter, sugar, and sour cream until smooth. Beat in eggs, mashed bananas, and vanilla. In a separate bowl, whisk flour, baking soda, and salt. Stir into banana mixture until just combined. Fold in walnuts if using.
2️⃣ Bake:
Spread batter evenly in the prepared pan. Bake for 25–30 minutes or until a toothpick inserted in the center comes out mostly clean. Cool completely in the pan.
3️⃣ Make the Glaze:
In a saucepan, melt butter. Remove from heat and whisk in powdered sugar and vanilla. Add milk 1 tablespoon at a time until it reaches a thick, pourable consistency.
4️⃣ Glaze & Slice:
Pour warm glaze over the cooled brownies. Spread evenly and let it drip slightly down the edges. Slice into squares and serve.
Notes
-
Banana Ripeness Tip: Use very ripe bananas with lots of brown spots. The riper they are, the sweeter and more flavorful your brownies will be.
-
Optional Add-ins: Stir in ½ cup chopped walnuts, pecans, or chocolate chips to add texture and flavor.
-
Dairy-Free Version: Substitute butter with plant-based butter, and sour cream with coconut yogurt or a dairy-free sour cream alternative.
-
Gluten-Free Version: Use a 1:1 gluten-free all-purpose flour blend. Add ½ tsp xanthan gum if your blend doesn’t include it.
-
Storage: Store in an airtight container at room temperature for up to 3 days, or refrigerate for 5 days. For longer storage, freeze individually wrapped squares for up to 2 months.
-
Serving Tip: These brownies are amazing served slightly warm with a scoop of vanilla ice cream or a drizzle of caramel.
-
Glaze Variations: Swap vanilla extract in the glaze with maple or almond extract for a fun twist. Add a pinch of cinnamon or nutmeg for spice.
