Ingredients for anna olson coffee cake

Gather these cozy ingredients for Anna Olson's iconic coffee cake—where buttery streusel meets vanilla swirls.

The butter here is non-negotiable—use European-style unsalted if you can find it. Plugrá or Kerrygold are my go-tos, but any good brand works. For the oats, Bob's Red Mill old-fashioned rolled oats blend perfectly into the streusel. The coffee granules should be strong—Starbucks Via or Folgers work great. Pro tip: Measure your flour by spooning it into the cup and leveling off—don't scoop directly from the bag or you'll end up with a dense cake. The walnuts should be toasted until golden and fragrant—about 5 minutes in a dry skillet.

No instant coffee? Brew a strong cup and let it cool completely—use about 2 tbsp of the cooled brew. Running short on sour cream? Plain Greek yogurt works in a pinch. Want extra richness? Swap half the milk for heavy cream. The vanilla extract can be imitation, but bottled vanilla has that authentic depth. For the streusel, if you forget the walnuts, pecans or almonds work just as well. And if you're feeling fancy, add a pinch of cardamom to the cake batter—it pairs beautifully with the coffee.

This cake keeps well for 3 days at room temperature, wrapped tightly in foil. For longer storage, freeze the whole cake (unwrapped) for up to 3 months. To reheat, wrap slices in a damp paper towel and warm for 10 seconds in the microwave. The streusel gets even more amazing the next day—trust me, it's worth making a double batch. Store the vanilla cream separately if you're prepping ahead; mix it in just before serving so it stays light and fluffy.

Step-by-step instructions for Anna Olson's coffee cake

Here's how to create that perfect balance of tender cake, rich vanilla swirls, and buttery streusel topping.

In a medium bowl, whisk together the 0.5 cup powdered sugar and 1 tbsp pure vanilla extract until smooth. This is your signature vanilla cream that gets swirled into the cake batter. I like to make this first so it's ready when we need it - it's the secret to those beautiful golden swirls you see in the finished cake.

Set this mixture aside while you prepare the cake batter. The vanilla cream will thicken slightly as it sits, which is perfect for creating those signature swirl patterns. If it gets too thick before using, just whisk in a few drops of milk to loosen it up.

In a large mixing bowl, combine the 3 cups all-purpose flour, 1.5 cups granulated sugar, 0.5 cup light brown sugar, 2 tbsp instant coffee granules, 1.5 tsp ground cinnamon, 0.5 tsp salt, and 2 tsp baking powder. Sift the flour mixture together to remove any lumps and ensure an even texture.

In a separate bowl, beat the 2 whole large eggs until frothy, then add the 0.5 cup melted unsalted butter, 1 cup whole milk, and 0.5 cup sour cream. Gradually mix the wet ingredients into the dry ingredients until just combined - don't overmix or your cake will be tough. The batter should be thick but pourable.

In another bowl, cut the 1 cup unsalted butter into small cubes and mix with the 1 cup old-fashioned rolled oats, 0.5 cup chopped walnuts, 0.5 cup granulated sugar (from the remaining), and 1 tsp ground cinnamon. Use your fingers to work the butter into the oat mixture until it resembles coarse crumbs with some pea-sized butter pieces remaining.

This is where the magic happens - the streusel should be crumbly but still hold together when pressed. If it's too dry, add a teaspoon of milk to bind it. The walnuts add a nice texture contrast and the cinnamon gives that warm coffee cake aroma. Save about 1/4 cup of this streusel mixture for the center of your cake.

Preheat your oven to 350°F. Grease a 9x13-inch baking pan and sprinkle with a little flour to prevent sticking. Pour half of the cake batter into the prepared pan, spreading it evenly. Drop spoonfuls of the vanilla cream mixture over the batter, spacing them about 2 inches apart.

Using a knife, gently swirl the vanilla cream into the batter in a circular motion. This creates those beautiful patterns you see in the finished cake. Pour the remaining batter over the vanilla cream, then sprinkle the reserved streusel mixture in the center. Finally, cover the entire cake with the remaining streusel topping, pressing down lightly.

Bake the coffee cake for 45-50 minutes or until a toothpick inserted in the center comes out clean. The edges should be golden brown and the top should be evenly covered with crisp streusel. If the streusel starts browning too quickly, tent the pan with aluminum foil to prevent over-browning.

Let the coffee cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. This resting time allows the cake to set properly and prevents it from falling apart when you try to slice it. The aroma as it bakes will make your kitchen smell like a cozy coffee shop!

Essential equipment for this recipe

Mixing Bowls

Invest in a set of stainless steel mixing bowls with measurements marked—3-quart and 5-quart sizes work perfectly for this recipe. I use OXO Good Grips because they’re durable, non-slip, and easy to clean.

The 3-quart bowl handles the cake batter and vanilla cream, while the 5-quart bowl is ideal for the streusel topping. Avoid plastic bowls for hot ingredients like melted butter—they can warp or melt. 🥣

Measuring Tools

Precision matters in baking, so grab a stainless steel measuring set with both dry and liquid measures. My go-to is the EZ Read Measuring Cups—they’re clear, easy to read, and include a built-in leveler for flour.

For the 2 tbsp instant coffee granules and 1.5 tsp cinnamon, a small measuring spoon set (like KitchenAid’s) ensures accuracy. Always spoon flour into dry measures and level it off—never scoop directly from the bag. 📏

Baking Pan

A 9x13-inch baking pan is essential for this recipe—Wilton’s Perfect Results or All-Clad’s stainless steel pans distribute heat evenly and prevent sticking. Avoid dark-colored pans (like black anodized) unless you love over-browned edges.

Line the pan with parchment paper for easy removal, but grease it lightly with butter or baking spray first to prevent sticking. Preheat the pan in the oven for 5 minutes before adding batter to ensure even baking. 🍰

Pastry Brush

For that signature golden streusel topping, a silicon pastry brush (like OXO’s) is your best friend. Use it to brush melted butter over the streusel before baking—this creates a crisp, caramelized crust.

A small offset spatula also comes in handy for spreading the vanilla cream swirls evenly. Avoid metal brushes, as they can scratch non-stick pans. 🎨

Wire Rack

Let your coffee cake cool on a wire cooling rack to prevent sogginess. I prefer a large, heavy-duty rack (like Nordic Ware’s) that fits your 9x13-inch pan. Place it directly on the counter or over a baking sheet to catch any crumbs.

Cooling the cake properly ensures clean slices and maintains that perfect streusel texture. Pro tip: Spritz the rack with cooking spray before cooling for easy cleanup. ❄️

Optional Extras

For a professional touch, consider a cake comb (like Wilton’s) to create those signature swirls in the vanilla cream—it’s faster than a knife and gives cleaner lines. A digital kitchen scale (for precise butter measurements) and a thermometer (to check oven temp at 350°F) are also game-changers.

If you’re feeling fancy, a silicone cake release mat eliminates the need for greasing entirely. 💡
