Moist Coffee Cake Recipe (Soft, Buttery & Cinnamon Crumb)

There is something deeply comforting about a warm slice of coffee cake with a tender crumb, a thick ribbon of cinnamon streusel, and a light vanilla glaze on top. Even better, this Moist Coffee Cake is simple enough for a cozy weekend bake, yet special enough to serve for brunch, holidays, or afternoon coffee with friends.

Unlike cakes that rely only on butter for richness, this version uses sour cream for extra moisture and a soft, velvety texture. If you enjoy bakery-style breakfast treats like Coffee Cupcakes, this recipe brings that same cozy café feeling into a classic homemade crumb cake.

What is it

Coffee cake is a soft butter cake traditionally served with coffee rather than made with coffee. Its signature features are a moist vanilla-cinnamon base, a generous streusel layer, and sometimes a simple glaze for a sweet finish.

This style of cake is especially popular for breakfast, brunch, and snack tables because it feels casual, sliceable, and crowd-friendly. In texture, it sits somewhere between a tender butter cake and a crumb-topped breakfast bake.

Why you’ll love it

• It has a soft, plush crumb thanks to sour cream, butter, and the right balance of flour and fat.
• The cinnamon streusel adds both sweetness and texture in every bite.
• It stays moist for days, which makes it perfect for make-ahead baking.
• It feels elegant with coffee, but easy enough for everyday baking.
• If you love layered desserts with rich, creamy flavor profiles like Classic Tiramisu, this cake offers that same comforting coffeehouse appeal in a simpler form.

Ingredients

For the cake batter

• 340g all-purpose flour
• 8g baking powder
• 3g baking soda
• 4g fine salt
• 170g unsalted butter, softened
• 200g granulated sugar
• 70g light brown sugar
• 3 large eggs, about 150g without shells
• 10g vanilla extract
• 240g full-fat sour cream
• 120g whole milk

For the cinnamon streusel

• 180g light brown sugar
• 125g all-purpose flour
• 8g ground cinnamon
• 2g fine salt
• 113g unsalted butter, melted

For the vanilla glaze

• 120g powdered sugar
• 20 to 30g milk
• 3g vanilla extract

How to make

Make the streusel

1. In a medium bowl, combine the brown sugar, flour, cinnamon, and salt.
2. Pour in the melted butter and mix with a fork until large, moist crumbs form.
3. Set aside while you prepare the batter.

Make the cake batter

1. Preheat the oven to 175°C and grease a 23×33 cm baking pan. Line it with parchment paper if you want easier lifting and cleaner slices.
2. In a bowl, whisk together the flour, baking powder, baking soda, and salt.
3. In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar until pale and fluffy, about 3 to 4 minutes.
4. Add the eggs one at a time, mixing well after each addition.
5. Mix in the vanilla extract.
6. Add the dry ingredients in three additions, alternating with the sour cream and milk. Begin and end with the dry ingredients, and mix just until combined.
7. Spread half of the batter into the prepared pan.
8. Sprinkle about half of the streusel over the batter.
9. Spread the remaining batter gently over the streusel layer.
10. Finish with the rest of the streusel on top.

Bake and glaze

1. Bake for 38 to 45 minutes, or until the center is set and a toothpick comes out with a few moist crumbs.
2. Cool the cake in the pan for at least 20 minutes.
3. Whisk together the powdered sugar, milk, and vanilla until smooth.
4. Drizzle the glaze over the slightly warm or fully cooled cake.

How To Serve

Serve this cake slightly warm or at room temperature with hot coffee, black tea, or a latte. For a more dessert-like presentation, add a spoonful of lightly sweetened cream on the side.

It also pairs beautifully with brunch spreads featuring fruit, yogurt, and pastries. If you want a richer serving idea, a small swipe of Chantilly Mascarpone on the plate makes it feel instantly more polished and bakery-style.

How To Store

Store the cake tightly covered at room temperature for up to 2 days, or in the refrigerator for up to 5 days. Because the batter contains sour cream, refrigeration helps preserve freshness longer.

Before serving leftovers, warm individual slices for 10 to 15 seconds in the microwave. This softens the crumb and makes the streusel taste freshly baked again.

FAQs

Does coffee cake contain coffee?

Usually, no. Traditional coffee cake is meant to be served with coffee, not necessarily flavored with it.

Why is my coffee cake dry?

Dry coffee cake usually comes from too much flour, overmixing, or overbaking. Measuring by grams and pulling the cake out when a few moist crumbs remain will help keep it tender.

Can I add nuts?

Yes. Chopped pecans or walnuts work especially well in the streusel. Add about 70 to 90g for extra crunch.

Can I make it richer?

Absolutely. You can drizzle it with a thicker icing or serve it with a side of Cream Cheese Frosting for a sweeter, more dessert-like finish.

Note

Use full-fat sour cream for the best texture. Low-fat versions contain more water and usually produce a less rich crumb.

Also, do not overwork the batter once the flour is added. A gentle mix keeps the cake soft and prevents a tough texture.

Nutrition information

This recipe yields about 12 generous slices. One slice contains roughly 360 to 430 calories, depending on how much glaze you use and how thick you cut each piece.

The streusel and butter give the cake its classic richness, while the sour cream helps retain moisture without making the crumb heavy.

Tips and Tricks

• Weigh the flour instead of scooping by cup for more reliable results.
• Use room-temperature butter, eggs, and sour cream so the batter blends smoothly.
• For thicker crumbs, chill the streusel for 10 minutes before topping the cake.
• For extra cinnamon flavor, add 1 to 2g cinnamon directly into the cake batter.
• If you enjoy soft, airy cakes like Molly Cake, think of this recipe as its cozier breakfast cousin: denser, richer, and topped with buttery crumbs instead of frosting.
