Step 1: Prepare the Flour
- Heat-Treat the Flour: To make the raw flour safe for eating, spread it on a baking sheet and bake at 350°F (175°C) for 5 minutes, or microwave in a bowl for 1 ½ minutes, stirring halfway through. Allow it to cool completely before using.
Step 2: Make the Cookie Dough Layer
- Cream Butter and Sugars: In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar until light and fluffy, about 2-3 minutes.
- Add Vanilla and Salt: Mix in the vanilla extract and salt until combined.
- Add the Flour Gradually: Add the heat-treated flour gradually to the butter mixture, mixing until it’s fully combined and smooth.
- Adjust Consistency with Milk: Add the milk, one tablespoon at a time, until the dough reaches a soft, cookie dough-like consistency.
- Fold in Chocolate Chips: Gently fold in the mini chocolate chips, distributing them evenly throughout the dough.
- Press into Pan: Line an 8×8-inch pan with parchment paper, leaving some overhang for easy removal. Press the cookie dough mixture evenly into the bottom of the pan, smoothing the top with a spatula.
Step 3: Prepare the Chocolate Topping
- Melt Chocolate Chips and Coconut Oil: In a microwave-safe bowl, melt the chocolate chips and coconut oil (or butter) in 20-second intervals, stirring between each interval until smooth.
- Spread Chocolate Layer: Pour the melted chocolate mixture over the cookie dough layer, spreading it evenly with a spatula.
Step 4: Chill and Set
- Refrigerate the Bars: Place the pan in the refrigerator for at least 1 hour, or until the chocolate layer is firm and the bars are fully set.
- Slice and Serve: Once set, lift the bars out of the pan using the parchment overhang. Use a sharp knife to cut into squares or bars.
Storage Tips
- Refrigerator: Store in an airtight container in the refrigerator for up to a week.
- Freezer: These bars freeze well; wrap individually and store in a freezer-safe bag for up to 3 months.
Helpful Tips
- Choose High-Quality Chocolate: For a smooth and rich topping, use good-quality chocolate chips or baking chocolate.
- Customize Your Mix-Ins: Try adding chopped nuts, different types of chocolate, or even toffee bits for a unique twist.
