Ingredients
For the Cake
- 2 c. (260 g.) unbleached all-purpose flour (RECOMMEND WEIGHING)
- ¾ c. (150 g) granulated sugar
- 2 tsp. baking powder
- ½ tsp. salt
- 1 large egg beaten
- ½ c. (120 g) milk whole or 2%
- ⅓ c. (80 g.) full-fat sour cream or plain greek yogurt
- 2 tbsp. (28 g.) salted butter melted & cooled
- 2 tbsp (28 g.) avocado oil or neutral oil
- 1 tsp. vanilla extract
For the Streusel Topping
- ¼ c. (55 g) brown sugar packed
- 1 tbsp. unbleached all-purpose flour
- 1 tsp. ground cinnamon
- 1½ tbsp. (21 g) butter melted
- ½ c. (60 g) pecans chopped (or walnut)
Instructions
- Prep the Pan: Preheat your oven to 375°F (190°C). Grease an 8x8-inch or 9x9-inch baking pan with butter or nonstick spray.
- Mix Dry Ingredients: In a large bowl, whisk together flour, sugar, baking powder, and salt until evenly mixed.
- Combine Wet Ingredients: In a medium bowl or large measuring cup, whisk the beaten egg, milk, sour cream, melted butter (or oil), and vanilla until smooth.
- Make the Batter: Pour the wet ingredients into the dry ingredients. Stir gently with a spatula or wooden spoon until just combined—lumps are fine; overmixing makes the cake dense. The batter will be thick and slightly sticky. Spread it evenly into the prepared pan.
- Prepare the Streusel: In a small bowl, mix together the brown sugar, flour, cinnamon, butter, and pecans or walnuts (optional). Use a fork to mix everything together. Sprinkle the streusel evenly over the batter.
- Bake: Bake for 30 minutes, or until a toothpick inserted in the center comes out clean and the streusel is golden. If doubling for a 9x13-inch pan, check at 35-40 minutes.
- Cool & Serve: Let the cake cool in the pan for 10-15 minutes. Slice and serve warm.

Notes
- Serving Tip: Best served warm with a pat of butter for extra indulgence—my kids’ favorite way to enjoy it!
- Doubling for a Crowd: For a 9x13-inch pan, double all ingredients exactly and check for doneness at 35-40 minutes. Perfect for brunches or potlucks.
- Storage: Store covered at room temperature for up to 2 days or in the fridge for 5 days. Reheat slices in the microwave for 20 seconds to revive that fresh-baked warmth.
- Ingredient Swaps: Use 2% milk if you don’t have whole milk. Pecans or walnuts work equally well for the topping.
