Ingredients
Wet Ingredients
- 3 large eggs
- 1/2 cup vegetable oil
- 1/2 cup milk
- 1/4 cup water
- 1 teaspoon vanilla extract
- 1 cup sour cream (or plain Greek yogurt)
Dry Ingredients
- 1 box Devil’s food cake mix (about 15.25 oz)
- 3.9 ounce box instant chocolate fudge pudding mix
- 1/2 teaspoon cinnamon
Chocolate Chips
- 2 1/2 cups semisweet chocolate chips (divided use: 2 cups for batter, 1/2 cup for topping)
Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C) to ensure it’s at the right temperature for baking the muffins evenly.
- Prepare Muffin Tins: Line two jumbo 6-cup muffin tins with jumbo cupcake liners or spray them with nonstick cooking spray. Note that most jumbo muffin pans have 6 wells, so two batches will make 12 muffins.
- Mix Wet Ingredients: In a large bowl, use an electric or stand mixer to beat together the 3 eggs, 1/2 cup oil, 1/2 cup milk, 1/4 cup water, and 1 teaspoon vanilla extract until well combined.
- Add Sour Cream: Stir in 1 cup sour cream (or plain Greek yogurt) until the mixture is smooth and well blended.
- Add Dry Ingredients: Add the box of Devil’s food cake mix, instant chocolate fudge pudding mix, and 1/2 teaspoon cinnamon to the wet ingredients.
- Combine Batter: Mix on low speed at first to prevent dry ingredients from flying out of the bowl, then increase speed and stir until well combined with no lumps.
- Fold in Chocolate Chips: Stir in 2 cups of semisweet chocolate chips evenly into the batter.
- Fill Muffin Cups: Using a spring-loaded cookie scoop or spoon, fill each lined muffin cup about 3/4 full with batter for perfectly sized jumbo muffins.
- Top with Chocolate Chips: Sprinkle the remaining 1/2 cup of semisweet chocolate chips on top of each muffin for a nice melty, chocolaty finish.
- Bake Muffins: Place muffin pans on the middle oven rack and bake for 20-25 minutes or until a toothpick inserted in the center comes out clean. Baking times can vary, so check for doneness starting at 20 minutes.
Notes
- Most jumbo muffin pans have 6 wells; bake in two batches for 12 muffins total.
- You can substitute sour cream with plain Greek yogurt to add protein and tanginess.
- Make sure to not overmix the batter to keep muffins tender.
- Use a toothpick to test doneness instead of relying strictly on time.
- Feel free to adjust the quantity of chocolate chips to your preference.
