Moist Mixed Berry Cake Recipe with Simple Ingredients!

One of my very favorite people happens to be one of the most thoughtful. We took a caravan of Pathfinders to Wyoming for the Pathfinder Camporee last summer – it was the trip of a lifetime! Wyoming has wild sunflowers like we have dandelions! They are so beautiful!

He brought a few home with him to try and propagate them. All but one died. He recently gave me the living one knowing how much I love them! I WAS THRILLED!! I am anxiously waiting for it to bloom!

As a thank you, I gave him this Mixed Berry Cake! He & his wife loved it so I am confident you will, too!

Why this Recipe Works

Butter and Sugar Create Light, Tender Crumb – Creaming the butter and sugar together traps air, which helps create a light and fluffy texture. It also gives the cake rich flavor and a slightly crisp edge.

Sour Cream Keeps It Extra Moist – Sour cream adds moisture and richness, preventing the cake from drying out. It’s slight tang also enhances the flavor of the berries.

Balanced Ingredients – A soft, tender cake with juicy berries throughout create a balanced sweet-tart flavor in every bite!

1 tsp Vanilla – Enhances the overall flavor with a warm, sweet aroma.

1 1/3 cup Flour – Forms the main structure of the cake.

1 1/4 tsp Baking Powder – Leavening agent that helps the cake rise and stay light.

How to Make a Mixed Berry Cake

Preheat oven to 350 degrees. Spray a 9″ round pan with non-stick spray and set aside.

In a large bowl, cream together 1/2 cup softened butter and 1 cup sugar until creamy.

Beat in 2 eggs. Then add in 1 tsp vanilla.

In a separate bowl, whisk together 1 1/3 cup flour, 1 1/4 tsp baking powder, and 1/4 tsp salt. Gradually beat the mixture into the creamed butter and sugar, alternately with 1/2 cup sour cream, beginning and ending with the flour mixture. Beat until just combined after each addition.

Gently fold in 1 cup fresh blueberries and 1 cup fresh raspberries.

Spread the batter evenly into the prepared pan.

Sprinkle remaining 1/4 cup sugar evenly over the top of the cake batter.

Bake for 35-40 minutes, until the top is crackly and lightly browned. The center should still jiggle just a little bit.

Let the cake cool completely in the pan.

Toss Berries in a Little Flour – Lightly coating your berries in flour helps prevent them from sinking to the bottom of the cake while baking.

Don’t Overload with Berries – It’s tempting to add more, but too many berries can make the cake soggy and heavy. Stick close to the recommended amount for the best texture.

Let Cake Cool Before Slicing – Allow the cake to cool so it sets properly. Cutting too early can cause it to fall apart.

If Using Frozen Berries – Don’t thaw them first. Add them frozen to avoid excess moisture and bleeding color.
