This is the moist, tender, sour-cream-based breakfast cake with a thick layer of cinnamon-pecan streusel running through the middle AND on top, finished with a sweet vanilla glaze drizzle. The kind of cake your grandma made for Sunday brunch. Serves twelve, sixty-five minutes, freezer-friendly, and it pairs with strong coffee like nothing else.
Fun fact: coffee cake is named for what you DRINK with it, not what’s IN it. The tradition started in 17th-century Germany when bakers made simple sweet cakes specifically to accompany coffee at afternoon kaffeeklatsch gatherings. American immigrants adopted it and the streusel-topped version became a brunch staple by the 1950s. Adding a glaze on top is a 1980s American bakery upgrade.
Why this recipe works
SOUR CREAM = MOIST. Sour cream’s fat + acid keeps the cake tender for 4+ days. Plain butter cakes dry out by day 2.
DOUBLE STREUSEL. Putting streusel in the MIDDLE of the cake creates a cinnamon ribbon through every slice — not just on top.
TOAST THE PECANS. Untoasted pecans taste flat. 8 minutes at 350°F gives them depth and crunch you can’t fake.
Ingredients
Serves 12.
Cinnamon-pecan streusel:
1 cup pecans, toasted and chopped
1/2 cup brown sugar, packed
1/3 cup all-purpose flour
1 tbsp ground cinnamon
1/4 cup melted butter
Pinch of salt
Cake:
1/2 cup unsalted butter, softened
1 cup granulated sugar
2 large eggs
1 cup sour cream (full fat)
2 tsp vanilla extract
2 cups all-purpose flour
1 1/2 tsp baking powder
1/2 tsp baking soda
1/2 tsp salt
Vanilla glaze:
1 cup powdered sugar
2-3 tbsp milk or cream
1 tsp vanilla extract
Pinch of salt
Instructions
Step 1: Toast the pecans
Preheat oven to 350°F (175°C). Spread pecans on a baking sheet. Toast 8 minutes until fragrant. Cool, then chop.
Step 2: Make the streusel
Combine toasted pecans, brown sugar, flour, cinnamon, salt, and melted butter. Stir until clumpy crumbs form. Set aside.
Step 3: Prep pan
Grease a 9×9 square baking pan and line with parchment with overhang for easy removal.
Step 4: Cream butter + sugar
Beat butter and granulated sugar 3 minutes until light and fluffy. Add eggs one at a time, then sour cream and vanilla. Mix until smooth.
Step 5: Mix dries + combine
Whisk flour, baking powder, baking soda, and salt in a separate bowl. Add to wet on low speed just until combined. Batter will be thick.
Step 6: Layer batter + streusel
Spread HALF the batter in the pan. Sprinkle HALF the streusel evenly over it. Spoon the remaining batter on top (it’ll be patchy — spread gently with a spatula to cover). Top with the rest of the streusel.
Step 7: Bake
Bake 40-45 minutes until a toothpick inserted in center comes out with a few moist crumbs. Cool in the pan 15 minutes.
Step 8: Make the glaze
Whisk powdered sugar, milk (start with 2 tbsp), vanilla, and salt until smooth and drizzle-able. Add more milk a teaspoon at a time if too thick.
Step 9: Glaze and serve
While cake is still slightly warm (not hot), drizzle glaze over the top in zigzag stripes. Let set 5 minutes. Cut into 12 squares.

Pro tips for the best pecan coffee cake with glaze
ROOM TEMP dairy. Cold sour cream + cold eggs = lumpy batter. Pull dairy out 1 hour before mixing.
DON’T overbake. Pull at 40 min if toothpick is even slightly clean. Cake firms as it cools — overbaked = dry.
USE BUNDT pan if you want. Same recipe in a 10-inch bundt pan — bake 50-55 min. Layer streusel in the middle the same way.
ADD FRUIT. Fold 1 cup blueberries, diced apple, or raspberries into the batter for a fruit-coffee cake mashup.
Frequently asked questions
Can I use Greek yogurt instead of sour cream?
Yes — full-fat Greek yogurt works 1:1. Texture stays the same, slightly more tang.
How long does it keep?
4 days at room temp covered. 1 week in the fridge but the texture firms up — bring to room temp before serving.
Can I freeze it?
Yes — freeze WITHOUT the glaze. Wrap individual slices in plastic, then foil. 3 months. Glaze after thawing.
Can I use walnuts instead of pecans?
Yes — toast them the same way. Slightly more bitter than pecans but still delicious.
Why is my streusel sinking?
Either the batter was too thin or you tapped the pan too hard. Spread the second layer of batter gently and don’t bang the pan.
