How to Make Reese’s Peanut Butter Earthquake
Preheat your oven: Start by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking dish with nonstick spray so nothing sticks around when it’s time to dig in.
Prepare the brownie mix: In a large bowl, combine the brownie mix with water, vegetable oil, eggs, and vanilla extract according to package directions. Stir until smooth—don’t over-mix or your brownies might turn out tough!
Layer the peanut butter mixture: In another bowl, mix together softened cream cheese and peanut butter until creamy. Add in some sweetened condensed milk until combined well—it should be dreamy and luscious!
Combine layers: Pour half of the brownie batter into the prepared baking dish. Spread the peanut butter mixture evenly over it before topping it off with more brownie batter. Swirl gently to create that earthquake effect without fully mixing.
Add chocolate chips: Sprinkle chocolate chips generously on top along with crushed peanuts if you’re feeling adventurous! These add great texture and flavor contrast when baked.
Bake it up: Place in your preheated oven and bake for about 30-35 minutes until edges are set but center is still slightly gooey. Trust me; that’s where all the magic happens!
Cool & Serve: Let it cool slightly before cutting into squares—if you can resist diving right in! Serve warm or chilled with a scoop of vanilla ice cream for an unforgettable experience.
And there you have it—the Reese’s Peanut Butter Earthquake that will have everyone begging for seconds! Get ready for smiles all around!
