Ingredients
Cinnamon Coffee Cake
114g all-purpose flour
3g baking powder
1g baking soda
1g fine salt
81g unsalted butter, softened
106g granulated sugar
71g beaten egg, at room temperature
7g vanilla extract
81g full-fat sour cream, at room temperature
21g whole milk, at room temperature
For the egg: Beat 2 large eggs together, then weigh out 71g. This gives the scaled recipe the correct amount of egg rather than rounding up to 1 or 2 whole eggs. A large egg weighs approximately 50g without the shell.
Cinnamon Swirl
152g packed light brown sugar
6g ground cinnamon
Streusel Topping
107g all-purpose flour
76g packed light brown sugar
47g granulated sugar
1g fine salt
61g unsalted butter, partially melted
Equipment
One 8 × 4 × approximately 2½-inch loaf pan
Parchment paper
Mixing bowls
Hand mixer or stand mixer
Digital kitchen scale
Small skull-shaped silicone mold, optional
Instructions
1. Prepare the Pan
Preheat the oven to 350°F.
Lightly grease an 8 × 4-inch loaf pan and line it with parchment paper, leaving an overhang along the long sides for easy removal.
2. Make the Cinnamon Swirl
Combine the brown sugar and cinnamon in a small bowl.
Mix until evenly blended and set aside.
3. Make the Streusel
Combine the flour, brown sugar, granulated sugar, and salt in a medium bowl.
Drizzle the partially melted butter over the mixture and gently toss with a fork until irregular buttery crumbs form.
Do not completely blend the streusel into a paste. You want a mixture of small and larger crumbs.
4. Make the Streusel Skulls
If using skull decorations, firmly press approximately half of the streusel into the skull cavities.
Freeze for 5–10 minutes, or until the shapes are firm enough to unmold cleanly.
Keep the remaining loose streusel at room temperature.
The original recipe likewise chills the molded streusel before placing the shapes onto the cake.
5. Mix the Dry Ingredients
Whisk together the flour, baking powder, baking soda, and salt.
Set aside.
6. Cream the Butter and Sugar
Beat the softened butter and granulated sugar on medium-high speed for approximately 2 minutes, until pale, smooth, and creamy.
Gradually add the 71g beaten egg and mix until incorporated.
Add the sour cream, milk, and vanilla. Beat just until combined.
7. Add the Dry Ingredients
Add the flour mixture to the wet ingredients.
Mix on low speed only until the flour disappears.
Do not overmix. The finished batter should be quite thick.
8. Assemble the Coffee Cake
Spread approximately half of the cake batter evenly across the bottom of the prepared pan.
Sprinkle the cinnamon-brown sugar mixture evenly over the batter, leaving a small border around the edges.
Carefully spoon the remaining cake batter over the cinnamon layer.
Because the batter is thick, add it in small spoonfuls across the surface before gently spreading it. This prevents the cinnamon layer from being pushed to one side.
9. Add the Streusel
Sprinkle a light layer of loose streusel over the batter.
Carefully unmold the chilled streusel skulls and arrange them over the top.
Scatter the remaining loose streusel between and around the skulls.
10. Bake
Bake at 350°F for approximately 38–43 minutes.
Begin checking at 38 minutes.
Insert a toothpick into an area of the cake crumb rather than directly through the cinnamon filling. It should come out clean or with a few moist crumbs but no wet cake batter.
The original 9 × 5-inch version bakes for 40–45 minutes; because this 8 × 4-inch version maintains a similar batter depth but has smaller dimensions, checking slightly earlier helps prevent overbaking.
11. Cool
Let the cake cool in the pan for 15 minutes.
Lift it out using the parchment overhang and transfer it to a wire rack.
Allow it to cool for at least another 20–30 minutes before slicing so the cinnamon layer and crumb can set.
Pro Tips
Weigh the Egg
This is important for the resized recipe. Don't simply use one egg or two eggs.
Beat the eggs first and weigh 71g for the batter.
Use the Exact Pan Size
This formula is designed for an 8 × 4-inch loaf pan approximately 2½ inches deep.
If your pan is substantially shallower, do not fill it more than about two-thirds to three-quarters full. King Arthur similarly recommends this filling range for quick-bread-style loaf cakes.
Keep the Ingredients at Room Temperature
Softened butter, room-temperature egg, sour cream, and milk emulsify more smoothly and help create an even, tender crumb.
Don't Overmix
Once the flour goes in, mix only until combined.
Overmixing encourages excess gluten development and can make the coffee cake tougher.
Keep the Cinnamon Layer Inside the Cake
Leave a narrow border around the cinnamon filling.
This helps keep the molten brown sugar away from the edges of the pan and creates a cleaner swirl when sliced.
Make the Streusel Clumpy
Stop mixing while visible crumbs remain.
Those irregular pieces bake into the crisp, bakery-style topping you want.
Chill the Skull Shapes
The streusel skulls should be completely firm before you try to unmold them.
If one breaks, simply press it back into the mold and freeze it a little longer.
Variations
Classic Cinnamon Streusel Coffee Cake
Skip the skull shapes and crumble all of the streusel evenly over the top.
You'll have the same cinnamon coffee cake in a year-round presentation.
Pumpkin Spice Coffee Cake
Replace the 6g cinnamon in the filling with 6g pumpkin pie spice.
Maple Cinnamon
Replace approximately 2g of the vanilla extract with maple extract for a subtle maple flavor.
Pecan Streusel
Add 25–30g finely chopped toasted pecans to the loose streusel.
Keep the streusel used for the molded skulls nut-free so their details remain defined.
Storage Instructions
Store the completely cooled coffee cake in an airtight container at room temperature for up to 2 days.
For longer storage, refrigerate for up to 5 days. Bring individual slices to room temperature before serving or warm briefly in the microwave.
For freezing, wrap individual slices tightly and place them in a freezer-safe container for up to 2 months.
Thaw at room temperature before serving.
Frequently Asked Questions
Can I use a 9 × 5-inch loaf pan?
You can physically bake this smaller recipe in one, but I don't recommend it.
The batter will spread across a larger surface area and produce a shorter, flatter loaf. The original full-size recipe was specifically written for a 9 × 5-inch pan.
Can I use one whole egg instead of weighing 71g?
For the best result, weigh the egg.
One large egg is approximately 50g, so using only one would leave the cake significantly short on egg; two whole eggs would add far too much.
Do I need a skull mold?
No.
The skulls create the Halloween design, but the cake works perfectly well with all of the streusel simply crumbled over the top.
