Easy Breakfast Bundt Coffee Cake

There's something magical about waking up to the smell of cinnamon and sugar caramelizing in the oven. My youngest sister discovered this recipe during her college baking phase, and it quickly became the Sunday morning tradition that actually got everyone out of bed before noon.

Last Christmas morning, I made three of these cakes because my extended family had descended upon our tiny apartment. My uncle actually went back for fourths, which is saying something for a man who claims he doesn't have much of a sweet tooth.

Ingredients

• 2 ½ cups all-purpose flour: The backbone of the cake, providing structure while still keeping things tender
• 2 tsp baking powder: Helps the cake rise beautifully without becoming too dense
• ½ tsp baking soda: Works with the acidic sour cream to create lift
• ½ tsp salt: Balances the sweetness and enhances all the flavors
• 1 cup unsalted butter, softened: Room temperature butter incorporates better for a lighter texture
• 1 ¼ cups granulated sugar: Sweetens the cake and creates that lovely golden crust
• 3 large eggs: Adds richness and helps bind everything together
• 1 cup sour cream: The secret ingredient that makes this cake incredibly moist and tender
• 2 tsp pure vanilla extract: Dont skimp here, it makes all the difference
• ½ cup brown sugar, packed: Creates the cinnamon swirl that makes this cake irresistible
• 2 tsp ground cinnamon: Warm, cozy spice that pairs perfectly with coffee
• ½ cup chopped pecans or walnuts: Optional, but adds a lovely crunch and nutty flavor
• ½ cup powdered sugar: For a beautiful snowy finish that makes it look bakery worthy

Instructions

Get your oven ready:

Preheat to 350°F and really thoroughly grease your Bundt pan, getting into all those crevices and curves

Whisk the dry team:

Combine flour, baking powder, baking soda, and salt in a medium bowl and set it aside

Cream the butter and sugar:

Beat them together for a solid 2 to 3 minutes until the mixture turns light and fluffy

Add the eggs:

Beat them in one at a time, letting each one fully incorporate before adding the next

Stir in the sour cream and vanilla:

Mix until just combined, scraping down the sides of the bowl to catch any stray bits

Combine everything:

Add the flour mixture in three parts, alternating with the sour cream, starting and ending with the flour

Mix the cinnamon swirl:

Stir together the brown sugar and cinnamon in a small bowl until well combined

Layer it all up:

Spread half the batter in the pan, sprinkle with half the cinnamon mixture and half the nuts, then repeat

Create the marble:

Gently run a knife through the batter once or twice, just enough to create those beautiful swirls

Bake until perfect:

Pop it in for 45 to 50 minutes until a toothpick comes out clean from the thickest part

Cool carefully:

Let it rest in the pan for 15 minutes before turning it out onto a wire rack

Finish with flair:

Dust generously with powdered sugar right before serving for that picture perfect look

My neighbor smelled this baking through our shared wall and actually knocked on the door to ask what I was making. We ended up sharing a slice on her porch while it was still slightly warm, which has become a monthly tradition whenever one of us bakes something new.

Making It Your Own

Sometimes I swap the sour cream for Greek yogurt when I want something a bit lighter. The texture changes just enough to feel different without losing that signature moistness that makes this cake so special.

Timing Is Everything

Ive learned the hard way that removing the cake too early means it collapses in the middle. That toothpick test is your friend, and even if it looks done, give it another few minutes if there's any resistance at all.

Serving Suggestions

This cake is actually better if you let it sit overnight, wrapped tightly on the counter. Something about the flavors melding together makes it even more incredible the next morning.

• Serve alongside your morning coffee or tea for the perfect breakfast treat
• Wrap individual slices in plastic for an easy grab and go breakfast
• Store at room temperature for up to three days in an airtight container

There's nothing quite like cutting into that first slice and seeing the cinnamon ribbons running through it like edible art. Hope this becomes your go to for all those lazy weekend mornings that call for something special.

Common Questions

→ Can I make this Bundt cake ahead of time?

Yes, this cake keeps beautifully for 3-4 days when stored in an airtight container at room temperature. The flavors actually develop and improve after a day. You can also bake it up to 2 months ahead and freeze it, tightly wrapped, then thaw at room temperature before serving.

→ What's the best way to prevent the cake from sticking to the pan?

Thoroughly grease your Bundt pan with softened butter or shortening, then dust with flour, getting into all the crevices. Alternatively, use a baking spray with flour. Let the cake cool for exactly 15 minutes after baking before inverting—too soon and it may tear, too late and it may stick.

→ Can I substitute the sour cream?

Plain Greek yogurt works beautifully as a 1:1 substitute for sour cream, yielding a slightly lighter texture. Full-fat yogurt provides the best moisture. For a dairy-free option, use coconut cream or a plant-based yogurt alternative, though the texture may vary slightly.

→ How do I know when the cake is done baking?

Insert a wooden skewer or toothpick into the thickest part of the cake. If it comes out clean or with just a few moist crumbs, the cake is done. The edges should pull away slightly from the pan, and the top should spring back when gently pressed. Start checking at 45 minutes.

→ Can I add other flavors to the cinnamon swirl?

Absolutely! Try adding 1 teaspoon of orange or lemon zest to the cinnamon sugar mixture for a bright citrus note. You could also mix in chopped toasted pecans or walnuts directly into the swirl layer, or add a pinch of nutmeg or cardamom to enhance the warm spice profile.

→ Why did my cake sink in the middle?

Sinking can occur from underbaking, opening the oven door too early, or using too much leavening. Ensure your oven is properly calibrated and avoid opening the door during the first 30 minutes of baking. Also measure your flour by weight if possible, or fluff and spoon it gently rather than scooping directly.
