Equipment

oven
9-inch square baking pan
mixing bowl
electric mixer
whisk
spatula
measuring cups
measuring spoons

Ingredients

Cake Batter

2 cups all-purpose flour
1 cup granulated sugar
1/2 cup unsalted butter softened
1 large egg
1 tsp pure vanilla extract
1/2 tsp baking soda
1/2 tsp salt
1 cup buttermilk at room temperature

Blueberries

1 1/2 cups blueberries fresh or frozen
1 tbsp all-purpose flour for tossing berries

Instructions

Preheat your oven to 350 degrees Fahrenheit. Grease a 9-inch square baking pan with butter or non-stick spray.
In a medium bowl, whisk together 2 cups of all-purpose flour, the baking soda, and the salt until well combined.
In a large mixing bowl, use an electric mixer to cream the softened butter and sugar together on medium speed for 2-3 minutes, until the mixture is light and fluffy.
Beat the egg and vanilla extract into the butter mixture until just incorporated. With the mixer on low, alternately add the flour mixture and the buttermilk to the wet ingredients, beginning and ending with the flour. Mix just until the batter is smooth with no dry streaks.
In a small bowl, gently toss the blueberries with the 1 tablespoon of flour until lightly coated. This helps prevent them from sinking. Fold the floured blueberries into the batter using a spatula until evenly distributed.
Pour the batter into the prepared pan and spread it into an even layer. Bake for 45 to 55 minutes, until the top is golden brown and a toothpick inserted into the center comes out clean.

Notes

Toss blueberries in flour to prevent sinking. Room temperature buttermilk ensures a smoother batter.

My Pro Tips for Soup Perfection

Lentil Selection: Rinse lentils thoroughly to remove any debris before adding them.
Vegetable Size: Dice vegetables uniformly for even cooking throughout the soup.
Layering Flavors: Sauté onions, carrots, and celery briefly for a deeper flavor base.
Final Seasoning: Always taste and adjust salt and pepper after cooking, as lentils absorb seasoning.

How to Store and Reheat Your Soup

Store: Cool completely and keep in an airtight container in the refrigerator for up to 5 days.
Freeze: Portion into freezer-safe containers, leaving space for expansion, for up to 3 months.
Reheat: Warm gently on the stovetop over medium-low heat or in the microwave, stirring occasionally.
Make-Ahead Tip: This soup tastes even better the next day, making it ideal for meal prep, much like my turkey taco soup.

Frequently Asked Questions

Yes, you can add dry lentils directly to the crock pot. They will soften perfectly as the soup simmers. There’s no need to pre-cook them, which makes this an easy lentil recipe.

What makes lentil soup taste better?

Building a flavorful base by sautéing aromatics like onions and garlic first adds depth. Using a quality broth and don’t forget to season well with salt and herbs at the end of cooking.

Why is my lentil soup mushy?

Lentils can become mushy if they are overcooked. Brown and green lentils hold their shape better than red lentils. Check the soup towards the end of the cooking time to ensure perfect texture.
