This version is different.

Cottage cheese adds:

• Creaminess

Peanut butter adds:

Oat flour keeps it wholesome and gluten-friendly.

Step 1: Blend (Optional but Recommended)

If you prefer a smoother texture, blend cottage cheese until creamy.

This ensures no visible curds in your mug cake.

Step 2: Mix Ingredients

In a microwave-safe mug (at least 12 oz size), add:

• Cottage cheese
• Peanut butter
• Honey
• Vanilla

Mix until smooth.

Add:

• Oat flour
• Baking powder
• Salt

Stir until fully combined.

Step 3: Microwave

Microwave for 60–90 seconds.

Cooking time depends on microwave strength.

Start with 60 seconds and check center.

The cake should be set but slightly soft on top.

Do not overcook.

Step 4: Cool Slightly

Let sit 1–2 minutes before eating.

This allows texture to settle.

Why Cottage Cheese Works So Well

Once blended, you won’t even taste it — just creamy texture.
