1. Prep & Preheat
Preheat oven to 350°F (175°C).
Grease a 9×13-inch baking pan generously with butter or nonstick spray.
Optional: Line bottom with parchment paper for easier removal.
2. Make the Cake Batter
In a medium bowl, whisk flour + baking powder + baking soda + salt. Set aside.
In a large bowl, beat softened butter + sugar with a hand mixer (or stand mixer) on medium-high 3–4 minutes until pale and fluffy.
Beat in eggs (one at a time), then vanilla.
Alternate adding dry ingredients and buttermilk to butter mixture:
→ Flour → Buttermilk → Flour → Buttermilk → Flour
Mix on low speed until just combined after each addition (don’t overmix).
Batter will be thick but pourable.
3. Bake Until Golden & Springy
Pour batter into prepared pan; smooth top with spatula.
Bake 30–35 minutes until:
→ Golden brown on top
→ Edges pull slightly from pan sides
→ Toothpick inserted in center comes out clean (no wet batter)
→ Center springs back when lightly pressed

⚠️ Don’t overbake: Cake continues cooking as it cools. Slightly underdone = better sauce absorption.
4. Poke the Holes (The Magic Step!)
Immediately upon removing from oven, use the handle of a wooden spoon or dowel to poke holes all over the warm cake.
How to poke:
→ Space holes 1–1.5 inches apart
→ Poke straight down to bottom of pan (don’t angle)
→ Make holes deep but not so wide they collapse
✨ Why poke? Creates channels for sauce to penetrate deep—not just sit on surface.
5. Make the Buttermilk Sauce
While cake bakes, prepare sauce:
→ In a medium saucepan, combine sugar + butter + buttermilk.
→ Cook over medium heat, stirring constantly, until butter melts and sugar dissolves (~3–4 mins).
→ Bring to a gentle boil; boil 1 minute exactly (set timer!).
→ Remove from heat; carefully stir in baking soda (it will foam vigorously—this is normal!).
→ Stir in vanilla + salt. Sauce will be thin and foamy.
6. Soak the Cake
Immediately after poking holes, pour warm sauce evenly over hot cake.
Use a spoon to gently guide sauce into holes if needed.
Let cake cool completely in pan (2+ hours)—sauce will absorb fully, creating a moist, glistening surface.
❗ Critical: Don’t rush this—cutting too soon = sauce runs off instead of soaking in.
