Picture a cinnamon-streusel cake that tastes right but leaves its top behind in the pan. A sour cream coffee cake bundt stays soft with full-fat sour cream and releases cleanly when the pan is prepared thoroughly and the cake cools before turning out.
It is also the baked half of a good morning cup, which is why it belongs in any answer to what food goes with coffee. The sections below cover the batter, the streusel, the pan, the bake and the storage, correcting the usual assumptions as they come up.
Sour cream in the batter
Full-fat sour cream keeps the crumb soft in a way that butter alone doesn’t, as Garnish with Lemon puts it. That is the core reason coffee cake recipes use it: the butter brings richness, and the sour cream keeps the crumb tender enough to feel like a treat rather than a dry slice.
Method matters as well as the ingredient. Jane’s Sweets mixes the baking soda into the sour cream well before the dairy goes into the rest of the batter, so the soda is fully blended before it meets the other ingredients.
Substitutions are where most misunderstandings start. King Arthur Baking allows low-fat sour cream or yogurt but specifically not nonfat. The Garnish with Lemon author reports that low-fat sour cream and Greek yogurt did not give the same result as full-fat. Jane’s Sweets would not swap all of the sour cream for yogurt. The practical reading:
- Want the cake as written: buy full-fat sour cream.
- Need to lighten it: low-fat is the furthest step down, and nonfat is the one to avoid.
- Want to use up yogurt: replace only part of the sour cream, not all of it.
Common assumptions, checked
| Common assumption | What the recipes show | Planning use |
|---|---|---|
| Any sour cream or yogurt behaves the same | Low-fat is acceptable but nonfat is not; full-fat gave the reported best result | Choose full-fat first, low-fat if needed, never nonfat |
| A well-greased bundt will release at once | A warm bundt will stick regardless of greasing; waiting 10 minutes and loosening the edges is the other recommended route | Let the cake rest in the pan before turning it out |
| The fridge keeps cake fresher | Wrapped cake keeps at room temperature for up to 3 days, and refrigeration dries it faster | Wrap well and leave it on the counter |
| The oven dial is the true temperature | Ovens can vary by 25°F or more from the dial | Use an oven thermometer and test early |
The cautions in this table come from Garnish with Lemon and King Arthur Baking.
Ingredient quantities and the cinnamon streusel
Quantities differ from one published recipe to the next, so follow one recipe’s proportions from start to finish rather than blending figures from several. The reference points below show where the main recipes sit.
- Cake base: the Garnish with Lemon recipe uses 2 cups flour and 1 cup unsalted butter, softened, alongside the full-fat sour cream.
- Cinnamon: Garnish with Lemon puts 1 tablespoon of ground cinnamon in its streusel, while Ina Garten’s version uses 1 1/2 teaspoon. Choose the larger amount for a pronounced cinnamon crumb and the smaller for a gentler spice.
- Sugar and fat in the streusel: King Arthur Baking combines brown sugar with cinnamon and pecans or walnuts, stirring until evenly crumbly. Ina Garten’s streusel uses cold unsalted butter, cut into pieces.
Keep the butter cold. Cold butter is what makes streusel crumbly instead of pasty, which is the difference between a topping with visible crumbs and a flat, sugary paste. Stop mixing as soon as the topping looks evenly crumbly.
Pan preparation and clean release
A bundt sticks when the pan is under-prepared or the cake is turned out too soon. Fix both and the decorative top comes out intact.
Coating the pan
Foster’s Market greases and lightly flours a 10-inch bundt pan. Ina Garten’s recipe greases the pan or uses cooking spray and then adds flour, warning that without the flour the cake may stick. For the most thorough coating, Garnish with Lemon recommends baking spray with flour, such as Baker’s Joy or PAM Baking. Choose the spray if your pan has deep detail; choose butter and flour if you want a simpler pantry method.
Turning it out
- Rest the cake in the pan. Foster’s Market cools it in the pan for 10 to 15 minutes, then turns it out to cool completely.
- Loosen the edges. King Arthur Baking waits 10 minutes, loosens the edges and then carefully turns the cake out of the pan.
- Cool it fully before glazing. The glaze and any dusting go on a cake that is already out of the pan.
If the cake still hangs on, the likeliest cause is rushing: a warm bundt will stick regardless of how well it was greased. Cooling is the correction, not more grease.
Bake time and temperature for a bundt pan
For a 10-inch bundt, 350°F with a first check at about 50 minutes is the safest plan. The published figures cluster tightly around that point.
- Foster’s Market: a 10-inch bundt pan at 350°F for 50 minutes to 1 hour, until golden brown (recipe).
- Ina Garten: a 10-inch tube or bundt pan at 350°F for 50-60 minutes, tested with a skewer or cake tester (recipe).
- Garnish with Lemon: 325°F for 50-60 minutes, with the first toothpick check at 50 minutes (recipe).
Treat the temperature and time as a pair from one recipe. Mixing the lower temperature with the shorter time, or the reverse, is how a cake ends up raw in the middle or overbaked at the edges.
Doneness is a toothpick or skewer call, not a clock call. Garnish with Lemon looks for a clean toothpick or one with a few dry crumbs. It also notes that ovens vary by 25°F or more from what the dial says, so an oven thermometer is a cheap way to know which end of the time range your oven will land on.
Glaze, serving and the coffee pairing
Streusel already gives this cake a sweet, crunchy top, so the glaze can stay light. Ina Garten’s version mixes 1/2 cup of sifted confectioners’ sugar with 2 tablespoons of maple syrup (recipe). Maple adds a note that sits well with cinnamon and works as a drizzle over a cake that has finished cooling.
Serve slices beside a hot cup of coffee: the soft crumb and cinnamon crumble suit a morning drink without needing anything else on the plate. For a savoury contrast, the coffee and cheese pairing guide shows another direction.

Storing leftover coffee cake
Wrap the cake well and keep it at room temperature for up to 3 days, as Garnish with Lemon advises. Avoid the refrigerator: cold air dries the cake faster, which undoes the softness the sour cream built in. Wrapping closely matters more than where the cake sits, because exposure to air is what dries out cut slices. Slice only what you plan to serve and keep the rest whole where possible.
Frequently asked questions
| Question | Answer |
|---|---|
| Can I bake this in a pan other than a bundt? | Yes. King Arthur Baking bakes its version in a 9 1/2-inch tube pan or a 9-inch square pan at 350°F for 30 to 40 minutes, and a glass pan may need 5-10 more minutes. |
| Which nuts go in the streusel? | Walnuts or pecans. King Arthur Baking names either, and Garnish with Lemon uses 1 cup of walnut halves or pieces. |
| Is a glaze or sugar dusting necessary? | No. King Arthur Baking dusts the top with non-melting sugar or confectioners’ sugar only if desired, so the cake is complete with streusel alone. |
