Preheat the oven to 350 degrees F. Spray an 8-inch square baking dish with nonstick cooking spray.

In a mixing bowl, combine the Pillsbury sugar-free brownie mix and Diet Coke together with a wooden spoon. Brownie mix will be runny.

Step 4:

Remove the brownies from the oven and let them cool completely in the baking dish.

Expert Tips

• When mixing the ingredients together, be careful not to overmix the batter. Overmixing can cause the brownies to become tough and chewy.
• Allow the brownies to cool completely before adding the marshmallow creme on top. This will prevent the creme from melting and becoming runny.
• You can customize the recipe by using different flavors of sugar-free brownie mix, such as chocolate fudge or dark chocolate, and by adding other ingredients like chopped nuts or chocolate chips.

Variations

• Add chocolate chips: For a little extra sweetness and texture, you can add sugar-free chocolate chips to the batter before baking.
• Use different nut butters: Instead of peanut butter powder, you can use almond butter powder or another type of nut butter powder for a different flavor.
• Use different sweeteners: Instead of using marshmallow creme, you can use a sugar-free frosting or whipped cream.
• Add fruit: For a healthier twist, you can add chopped strawberries or raspberries on top of the brownies instead of the marshmallow creme.

Storing & Freezing

Storing: To store skinny peanut butter brownies, allow them to cool completely and then place them in an airtight container. You can keep them at room temperature for up to 3 days or in the refrigerator for up to 1 week.

Freezing: If you want to freeze the brownies, wrap them tightly in plastic wrap and then place them in an airtight container or freezer bag. They will last in the freezer for up to 3 months.

Reheating: Remove them from the freezer and let them come to room temperature. You can also warm them up in the microwave or oven if you prefer to eat them warm. Just be sure to remove the plastic wrap before reheating.
