1-First Step: Prepare the brownie batter Melt butter in a microwave-safe bowl for 1-2 minutes. Stir in sugar until smooth. Add eggs one at a time, whisking well. Mix in vanilla. Sift flour, cocoa, and salt together, then fold into wet ingredients until just combined. Batter will be thick. Fold in 1 cup chopped pecans. Spread half into prepared pan.

2-Second Step: Make the caramel layer Combine chopped caramel candies and heavy cream in a saucepan over low heat. Stir constantly for 3-5 minutes until smooth and pourable. Drizzle half over batter in pan, swirling gently with a knife for marble effect. Sprinkle remaining 1/2 cup pecans on top.

3-Third Step: Add the top brownie layer Spread remaining batter over caramel-pecan layer. It helps to dollop and smooth carefully to avoid disturbing the filling. Tap pan on counter to release air bubbles. Bake for 25 minutes.

4-Fourth Step: Finish baking and add chocolate Remove from oven, drizzle remaining caramel over top. Sprinkle chocolate chips evenly. Return to oven for 10-15 more minutes until edges set but center jiggles slightly. Total bake time: 35-40 minutes. Cool in pan for 30 minutes, then chill 2 hours for clean cuts.

5-Final Step: Finishing touches and serving Lift brownies from pan using parchment. Cut into squares. Serve warm with ice cream or at room temp. Store as noted below. Yields 24 servings. Pro tip: Use a hot knife for gooey slices.
