Instructions

In a separate bowl, combine 4 cups flour, 1 cup cocoa powder, and 1 tsp salt. Pour this into your batter and mix thoroughly. Dissolve 2 tsp baking soda in 1 cup hot water, then add to the batter.
Scoop tablespoons of batter onto your greased cookie sheets. Bake for 8 minutes until firm, but don’t overbake! Let the cookies cool briefly, then move them to a wire rack.
For the filling, mix 1 1/2 cups shortening, 4 cups powdered sugar, and 1/4 cup flour until light and fluffy. Gradually beat in 1/4 cup milk and 1 1/2 tbsp vanilla. Fold in 2 beaten egg whites.
Once your cookies are completely cool, spread a tablespoon of filling on one cookie and top with another. Your whoopie pies are ready to enjoy!

Remember to watch your baking time if you make changes. New ingredients may cook differently. Check your whoopie pies often to avoid burning.
How To Make It Diabetes-Friendly
To make these whoopie pies better for people with diabetes, you can try a few easy swaps. Replace the white sugar with a sugar substitute like stevia or erythritol. These work well in baking and have little effect on blood sugar.
Instead of all-purpose flour, use almond flour or coconut flour. These low-carb options add fiber and nutrients. You may need to adjust the liquid in the recipe when using these flours.
For the filling, skip the powdered sugar. Try a sugar-free pudding mix or whipped cream cheese sweetened with stevia. This cuts carbs while keeping the creamy texture.
Here are some more tips:
• Use sugar-free cocoa powder
• Replace milk with unsweetened almond milk
• Add cinnamon or vanilla for flavor without sugar
• Make smaller pies to control portion size
Remember to check with your doctor about any diet changes. Enjoying treats in moderation can still be part of a healthy eating plan for diabetes.
Tips, Tricks & Storing
Use room temperature ingredients for better mixing. This helps create a smoother batter and fluffier filling.
Don’t overmix the batter. Stop mixing as soon as everything is combined to keep the cookies light and tender.
For uniform cookies, use an ice cream scoop to portion the batter. This ensures even baking and prettier whoopie pies.
Let the cookies cool completely before adding filling. Warm cookies will cause the filling to melt and slide off.
Store your whoopie pies in an airtight container at room temperature for 2-3 days. Place wax paper between layers to prevent sticking.
For longer storage, refrigerate whoopie pies for up to 1 week. Bring them to room temperature before eating for the best texture and flavor.
You can freeze whoopie pies for up to 3 months. Wrap each one in plastic wrap, then place in a freezer bag. Thaw in the fridge overnight.
Try different flavors! Add peppermint extract to the filling for a minty twist, or use pumpkin puree in the batter for a fall treat.
For extra-fluffy filling, beat it on high speed for 3-5 minutes. This incorporates more air, making it light and creamy.
