Ingredients
Scale
- 1 ½ cups (190 g) all-purpose flour
- ¾ cup (150 g) granulated sugar
- ½ cup (120 ml) milk
- 2 tsps baking powder
- ¼ tsp salt
- 1 large egg
- ¼ cup (60 ml) vegetable or canola oil
- 1 tsp vanilla extract
- ½ cup (100 g) brown sugar
- 2 tbsps (30 ml) melted butter
- 2 tbsps (15 g) all-purpose flour
- 2 tsps cinnamon
- ½ cup (60 g) chopped walnuts (optional)
- ¾ cup (90 g) powdered sugar
- 1 tbsp (15 ml) butter, room temperature
- 1 tbsp (15 ml) milk (add more if needed)
Instructions
- Oven Preparation: Preheat oven to 375°F (190°C) and line a 9×9-inch baking dish with parchment paper or grease thoroughly.
- Batter Creation: Whisk egg until smooth, then blend sugar, milk, salt, oil, and vanilla into a harmonious mixture. Sift flour and sprinkle baking powder across the surface, gently folding ingredients until just combined.
- Streusel Crafting: Melt butter in a microwave-safe container, then mix brown sugar, cinnamon, flour, and chopped walnuts until fully integrated and crumbly.
- Cake Assembly: Pour batter into prepared dish, ensuring even distribution. Generously sprinkle streusel over the surface, using fingertips to gently press topping into the batter with 12-18 random punctures.
- Baking Process: Bake for 25-30 minutes, checking for moist crumbs with a toothpick. Remove from oven and allow to cool slightly.
- Optional Finishing: Prepare icing by whisking butter and powdered sugar, gradually adding milk to create a smooth drizzle. Delicately spread over warm cake just before serving.
Notes
- Master Mixing Technique: Avoid overmixing batter to prevent tough, dense cake texture; fold ingredients gently until just combined.
- Streusel Embedding Strategy: Create random toothpick holes to help streusel sink naturally into cake without completely disappearing during baking.
- Temperature Precision: Use room temperature ingredients for smoother blending and more consistent cake rise, especially with eggs and milk.
- Moisture Control: Check cake doneness with toothpick test, aiming for moist crumbs rather than completely clean stick to ensure tender, soft interior.
