Classic Cinnamon Streusel Coffee Cake (Soft, Buttery & Perfect with Coffee)

About This Recipe

This classic coffee cake is everything a good coffee cake recipe should be:

• Texture
  • Soft, tender, buttery crumb
  • Thick, crunchy cinnamon streusel on top
  • Optional cinnamon-sugar ribbon through the middle
• Flavor
  • Warm cinnamon
  • Rich vanilla cake
  • Just sweet enough without being a “frosted” cake

It’s perfect for:

• Holidays like Christmas, Easter, and Mother’s Day
• Potlucks, office treats, and “bring-a-dessert” days

Baked in a simple 9×13 pan, this coffee cake stays moist for days thanks to sour cream (or Greek yogurt) in the batter.

Ingredients: What You’ll Need

For the Cinnamon Streusel Topping (and Middle Ribbon)

• 1 cup (125 g) all-purpose flour
• 1 cup (200 g) light brown sugar, packed
• 2 tsp ground cinnamon
• ¼ tsp fine sea salt
• ½ cup (113 g) unsalted butter, melted and slightly cooled
• Optional: ½ cup (60 g) chopped pecans or walnuts

For the Coffee Cake

• 2½ cups (300 g) all-purpose flour
• 2 tsp baking powder
• ½ tsp baking soda
• ½ tsp fine sea salt
• 1 cup (200 g) granulated sugar
• ½ cup (113 g) unsalted butter, softened
• ½ cup (120 ml) neutral oil (canola, vegetable, or light olive)
• 3 large eggs, room temperature
• 2 tsp pure vanilla extract
• 1 cup (240 g) sour cream or full-fat Greek yogurt, room temperature
• ½ cup (120 ml) milk (whole or 2%), room temperature

Instructions: Step-by-Step Preparation

1. Prep the Pan & Oven

• Preheat oven to 175°C / 350°F.
• Grease a 9×13-inch (23×33 cm) baking pan.
• For easiest removal and slicing, line with parchment paper and lightly grease.

2. Make the Cinnamon Streusel

In a medium bowl:

1. Stir together:
   • Flour
   • Brown sugar
   • Cinnamon
   • Salt
2. Pour in melted butter and mix with a fork until:
   • Clumps form, and the mixture looks like coarse crumbs.
3. Stir in nuts if using.
4. Set aside. You’ll use about ⅔ for the top and ⅓ for the middle layer.

3. Mix Dry Ingredients for the Cake

In a separate bowl, whisk:

• Flour
• Baking powder
• Baking soda
• Salt

Set aside.

4. Cream Butter, Oil & Sugar

In a large mixing bowl:

1. Beat:
   • Softened butter
   • Granulated sugar
2. Beat on medium for 2–3 minutes until light and fluffy.
3. Add oil and mix until combined.

5. Add Eggs, Vanilla & Dairy

1. Add eggs one at a time, mixing well after each.
2. Beat in vanilla.
3. In a measuring jug, whisk together:
   • Sour cream
   • Milk

6. Combine Wet & Dry

1. Add dry ingredients to the butter mixture in 3 additions, alternating with the sour cream/milk mixture in 2 additions:
   • Start and end with dry ingredients.
2. Mix on low speed just until combined—do not overmix.
3. The batter will be thick and creamy.

7. Layer the Coffee Cake

1. Spread about half of the batter into the prepared pan:
   • Use an offset spatula or the back of a spoon.
   • It will be thick—take your time to spread it evenly.
2. Sprinkle ⅓ of the streusel evenly over the batter to create a cinnamon ribbon.
3. Gently dollop and spread the remaining batter over the streusel:
   • Dot spoonfuls across the top, then smooth carefully without disturbing the layer too much.
4. Top with the remaining ⅔ streusel, covering the surface evenly.

8. Bake

• Bake at 175°C / 350°F for 40–50 minutes, until:
  • A toothpick inserted in the center comes out clean or with a few moist crumbs.
• If the top is browning too quickly toward the end, tent loosely with foil.

9. Cool & Serve

• Cool the coffee cake in the pan on a wire rack for at least 30–40 minutes.
• Serve warm or at room temperature, cut into squares.

Optional: Dust with powdered sugar just before serving.

How to Store It

• Room temperature:
  • In an airtight container for 2–3 days.
• Refrigerator:
  • Up to 5–6 days (bring to room temp or warm briefly before serving).

For the best texture, keep tightly covered to prevent drying.

Smart Ingredient Swaps

• No sour cream?
  • Use full-fat Greek yogurt (1:1).
• Nut-free:
  • Omit nuts; streusel is still delicious.
• More cinnamon flavor:
  • Add ½–1 tsp cinnamon directly to the cake batter.
• Lower sugar:
  • Reduce granulated sugar in the cake to ¾ cup (150 g); the cake will be slightly less sweet but still good.

How to Serve It

• Breakfast or brunch:
  • With hot coffee, tea, or a latte.
• Dessert:
  • Warm with a scoop of vanilla ice cream.
• For guests:
  • Serve on a platter with fresh berries and a dusting of powdered sugar.

Also ideal for potlucks and holiday mornings (Thanksgiving, Christmas, Easter) because it can be baked ahead.

Cultural Background & Personal Touches

Despite the name, coffee cake traditionally doesn’t contain coffee—it’s meant to be eaten with coffee.

This cinnamon streusel version is:

• Very much in the American bakery tradition
• A cousin of crumb cakes and streusel cakes from German baking
• Known for its thick, crunchy crumb topping and soft, moist base

This recipe focuses on:

• A tender, sour cream–based cake that stays moist
• A generous amount of streusel (on top and in the center)
• Straightforward steps that even newer bakers can follow

Seasonal Variations

• Fall:
  • Add ½ tsp nutmeg and a pinch of cloves to the streusel.
  • Fold diced apple or pear into the batter.
• Winter (Holiday):
  • Add orange zest to the batter.
  • Top with a light vanilla glaze instead of powdered sugar.
• Spring:
  • Serve with fresh berries and a dollop of lightly sweetened whipped cream.

Why is my coffee cake dense?

• Common reasons:
  • Overmixing the batter after adding flour
  • Old baking powder/baking soda
  • Too much flour (scoop lightly or weigh)

Can I halve the recipe?

• Yes. Bake in an 8×8-inch (20×20 cm) pan and reduce baking time slightly (start checking around 30–35 minutes).
