Why you’ll love these jumbo double chocolate chip muffins
These muffins stand out for a few reasons:
- Crunchy, bakery-style domed tops
- Rich, concentrated chocolate flavor
- Moist crumb studded with melty chocolate chips
- Simple method that comes together quickly

What’s the difference between a muffin and a cupcake?
People often ask how muffins and cupcakes differ. The differences are subtle but meaningful:
- Muffins usually contain less sugar than cupcakes and can be made with all-purpose or whole wheat flour.
- Cupcakes are almost always topped with frosting; muffins are not.
- Muffins are typically denser; cupcakes are lighter and cake-like.
- Muffins can be savory or sweet; cupcakes are a sweet dessert.
- Preparation differs: cupcake batters are often creamed (butter and sugar beaten together) while muffin batters are mixed by combining wet ingredients and folding in dry ingredients for a thicker batter.

How to enhance the chocolate flavor
A small amount of hot coffee in the batter will intensify the chocolate notes without imparting a coffee taste. Use hot, freshly brewed coffee for best results; if you prefer not to use coffee, hot water will work as a substitute. The coffee reacts with cocoa to deepen the chocolate profile and give a more complex flavor.

The secret to moist double chocolate muffins
Moisture and tenderness come from a few deliberate choices in this recipe:
- Use oil rather than butter. Neutral oils (vegetable, canola, or grapeseed) keep the crumb moist; avoid olive oil because its flavor is more pronounced.
- Include milk and sour cream (or full-fat plain yogurt) for added richness and a tender texture.
- Do not overmix once the flour is added—mix until the dry ingredients are just incorporated to avoid a tough muffin.

Baking technique for bakery-style tops
To achieve tall, domed muffin tops, start baking at a higher temperature (425°F) for a few minutes, then reduce the oven to 350°F for the remainder of the bake time. The initial heat jump helps the batter rise quickly and form those signature domes.
For true jumbo bakery-style muffins, use a jumbo muffin pan. This recipe makes about 8 jumbo muffins; baking times are longer than for standard muffins—see the recipe instructions below.

How to make these muffins (overview)
- Preheat oven and prepare a jumbo muffin pan with liners or nonstick spray.
- Whisk dry ingredients (flour, baking powder, salt) together and set aside.
- Combine cocoa powder with hot coffee to make a paste that deepens the chocolate flavor.
- Beat oil and brown sugar until the mixture looks slightly grainy, then add the cocoa paste, milk, sour cream, eggs, and vanilla.
- Fold in the flour mixture until just combined, then stir in most of the chocolate chips or chunks, reserving some to sprinkle on top.
- Fill each jumbo cup to the top, sprinkle with remaining chocolate, and bake: 5 minutes at 425°F, then lower to 350°F and bake 20–25 minutes more (for jumbo). Adjust for standard-size muffins.
- Cool in the pan for 5–10 minutes, then transfer to a wire rack.


Tips for success
- Use a high-quality unsweetened cocoa powder and good chocolate chips or chunks; quality ingredients noticeably improve flavor.
- Muffins are best served warm when the chocolate is gooey. Reheat gently in the microwave or oven if serving later.
- Avoid overmixing after adding the flour to keep the crumb tender.
Storage
Let muffins cool completely, then store in an airtight container at room temperature for up to 3 days or in the refrigerator for up to one week. To freeze, place cooled muffins in a freezer bag for up to 3 months. Thaw at room temperature or warm briefly in the microwave on low power.

Ingredients (yields 8 jumbo muffins)
- 2 1/4 cups all-purpose flour
- 1 tablespoon baking powder
- 1 teaspoon kosher salt
- 1/2 cup unsweetened cocoa powder
- 1/2 cup hot freshly brewed coffee (or hot water)
- 1/2 cup neutral vegetable or canola oil
- 1 cup packed brown sugar
- 1 cup whole milk
- 1/2 cup sour cream (or full-fat plain Greek yogurt)
- 2 large eggs, lightly beaten
- 1 tablespoon vanilla extract
- 1 1/2 cups semi-sweet chocolate chunks or chips, divided
Instructions
- Preheat oven to 425°F. Line a jumbo muffin pan with paper liners or spray with nonstick spray.
- In a medium bowl, whisk together the flour, baking powder, and salt; set aside.
- In a small bowl, whisk the cocoa powder with the hot coffee until a thick paste forms; set aside.
- In a large bowl or stand mixer, beat the oil and brown sugar on medium speed until blended and slightly grainy (about 1–2 minutes).
- Add the cocoa-coffee paste and mix briefly to combine.
- With the mixer on low, add the milk, sour cream, beaten eggs, and vanilla. Mix on medium just until combined.
- Slowly add the flour mixture and mix on low until just combined—do not overmix.
- Fold in 1 cup of the chocolate chunks or chips. Fill each muffin cup to the top and sprinkle the remaining 1/2 cup of chocolate on top.
- Bake 5 minutes at 425°F, then reduce oven temperature to 350°F and bake 20–25 minutes more for jumbo muffins (18–22 for standard), or until a toothpick inserted in the center comes out clean. Check for doneness after 15 minutes as ovens vary.
- Allow muffins to cool in the pan for 5–10 minutes, then transfer to a wire rack to cool completely.
Notes
- Store cooled muffins in an airtight container at room temperature up to 4 days or freeze for up to 3 months.
- For the best texture, serve warm; reheat gently before serving.
- Nutritional data provided on the original recipe is based on 8 jumbo muffins; actual values depend on exact ingredients and portion sizes.
