👩🍳 Step-by-Step Instructions
1️⃣ Preheat Oven
Preheat to 350°F (175°C). Grease a 9×13-inch baking dish.
2️⃣ Heat the Peanut Butter Mix
In a saucepan, combine butter, water, and peanut butter. Heat over medium until melted and smooth. Remove from heat and cool slightly.
3️⃣ Mix Dry Ingredients
In a large bowl, whisk together flour, sugar, baking soda, and salt.
4️⃣ Add Wet Ingredients
Pour the warm peanut butter mixture into the dry ingredients. Stir in eggs, milk, and vanilla until smooth.
5️⃣ Bake the Cake
Pour the batter into the prepared dish. Bake for 30–35 minutes, or until a toothpick comes out clean.
6️⃣ Top Immediately with Chips
Right after removing from the oven, sprinkle the chocolate chips over the hot cake. Let them melt and soften for 5–10 minutes, then gently spread if desired — or leave them whole!
