To nail this classic coffee cake, you’ll want to gather these ingredients:

  • 1 teaspoon baking powder (for a light rise)
  • ½ teaspoon baking soda (helps with leavening and browning)
  • ½ teaspoon salt (balances sweetness)

• Wet Ingredients

  • 1 cup unsalted butter, softened (for richness and moisture)
  • 1 ½ cups granulated sugar (sweetness and moisture retention)
  • 3 large eggs (binding and structure)
  • 1 teaspoon pure vanilla extract (aroma and flavor enhancer)
  • 1 cup sour cream or plain yogurt (adds moisture and tang)

• Cinnamon Swirl

  • ¾ cup brown sugar (for deep caramel notes)
  • 2 tablespoons ground cinnamon (the star spice)
  • ½ cup finely chopped walnuts (toasted for best flavor)

• Optional Crumb Topping

  • ½ cup flour
  • ⅓ cup sugar (white or brown)
  • ¼ cup cold butter, cubed
  • ½ cup chopped walnuts

How To Make Grandma’s Cinnamon Walnut Coffee Cake

Let’s walk through the steps, with a little chatter about why each one matters:

1. Prep And Preheat

   • Preheat your oven to 350°F (175°C).
   • Grease and flour a 9×13-inch baking pan, or line it with parchment paper for easy removal.

2. Mix Dry Ingredients

   • In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
   • This ensures your leavening agents are evenly distributed, so the cake rises uniformly.

3. Cream Butter And Sugar

   • In a large bowl, beat the softened butter and granulated sugar until light and fluffy (about 3-4 minutes).
   • This step traps air, creating a tender crumb in your cake.

4. Add Eggs And Vanilla

   • Beat in the eggs one at a time, making sure each is fully incorporated.
   • Add vanilla extract for that warm, inviting aroma.

5. Combine Wet And Dry

   • Alternately add the dry ingredients and sour cream to the butter mixture, starting and ending with the dry.
   • Mix gently, just until combined – overmixing can make the cake tough.

6. Prepare The Cinnamon Swirl

   • In a small bowl, combine brown sugar, cinnamon, and chopped walnuts.
   • Toast walnuts lightly in a dry pan before chopping to maximize flavor.

7. Assemble The Cake

   • Spread half the batter evenly in your prepared pan.
   • Sprinkle half the cinnamon swirl mixture evenly over the batter.
   • Spread the remaining batter on top.
   • Finish by sprinkling the remaining cinnamon swirl.

8. Optional Crumb Topping

   • Combine flour, sugar, and cold butter in a bowl.
   • Use your fingers or a pastry cutter to create coarse crumbs.
   • Mix in walnuts and sprinkle generously on top of the batter.

9. Bake

   • Bake for 40-45 minutes, or until a toothpick inserted in the center comes out clean.
   • Let it cool slightly before slicing – the aromas alone will be irresistible!

Ingredient Science Spotlight

Ever wondered why sour cream or yogurt is used here? It’s all about moisture and tenderness. The acidity in sour cream reacts with the baking soda, creating tiny bubbles that help the cake rise and remain moist.

• Butter coats the flour proteins, limiting gluten formation, so the cake stays soft.
• Brown sugar adds moisture due to its molasses content and deep caramel notes that elevate the flavor.
• Toasted walnuts release oils and develop a richer flavor compared to raw nuts.
• Cinnamon contains cinnamaldehyde, which gives that warm, spicy scent that enhances sweetness and overall taste perception.

This recipe is a beautiful balance of chemistry and tradition – every ingredient plays a role in making the cake unforgettable.

Expert Tips

Here are some insider tips to take your coffee cake from great to legendary:

• Use room temperature ingredients – this ensures even mixing and a smooth batter.
• Don’t overmix once the flour is added – overworking gluten makes the cake dense.
• Toast your walnuts on a dry pan for 3-5 minutes, shaking often – it unlocks incredible aroma and crunch.
• Sour cream vs. yogurt? Sour cream yields a richer crumb, but plain Greek yogurt is a good substitute if needed.
• Swirl gently but thoroughly – you want those cinnamon ribbons in every bite.
• If you want an extra glossy top, brush the cake with a simple syrup or a thin glaze of powdered sugar mixed with milk once cooled.

Recipe Variations

Feeling adventurous? Here are some fun twists you can try:

• Swap walnuts for pecans or almonds for a different nutty crunch.
• Add raisins or dried cranberries to the cinnamon swirl for bursts of fruity sweetness.
• Make it gluten-free by using a 1:1 gluten-free baking flour blend.
• Add a cream cheese layer in the middle for an ultra-rich surprise.
• Turn it into muffins for portable, individual treats.
• Top with a simple vanilla glaze for an extra sweet finish.
