Instructions

1. Preheat Your Omnia Oven
Place the Omnia oven base on your RV or camp stove over medium heat. Let it heat for a few minutes while you prepare the batter .

2. Mix the Dry Ingredients
In a medium bowl, whisk together the flour, sugar, cocoa powder (if using), baking powder, and salt until well combined.

3. Mix the Wet Ingredients
In a separate bowl, whisk together the milk, oil or melted butter, egg, and vanilla extract until smooth.

4. Combine the Batter
Pour the wet ingredients into the dry ingredients and stir gently until just combined. A few lumps are okay—don’t overmix, or the cake will be tough. Fold in the chocolate chips.

5. Prep the Omnia Pan
Generously grease the Omnia baking pan with butter or cooking spray to prevent sticking . If you have the silicone liner, place it in the pan for even easier cleanup.

6. Bake the Cake
Pour the batter into the prepared Omnia pan and spread it evenly. Sprinkle extra chocolate chips on top if desired. Cover with the Omnia lid and bake over low to medium-low heat for 25-30 minutes .

Important: The Omnia can be hotter at the bottom than the lid thermometer suggests, so keep the heat moderate to prevent burning . The cake is done when a toothpick inserted in the center comes out clean .

7. Cool and Serve
Remove the Omnia from the heat and let the cake cool in the pan for 10 minutes before transferring to a wire rack or serving plate. Dust with powdered sugar if desired. Serve warm or at room temperature.

Tips for Perfect Omnia Oven Chocolate Chip Cake

Temperature Control on Your Camp Stove
The Omnia oven can run hotter at the bottom, so it’s often better to cook at a lower temperature for a longer time to prevent burning . Start with medium heat to get the oven up to temperature, then reduce to low or medium-low to maintain a steady bake. If the cake is browning too fast on top while the center is still raw, reduce the heat further.

Using the Omnia Silicone Liner
Using the Omnia silicone liner or a silicone baking mold makes cleanup incredibly easy and prevents sticking . If you don’t have the liner, simply grease the Omnia baking pan generously with butter or cooking spray.

Making It Your Own
This recipe is incredibly versatile. You can add 1/2 cup of chopped nuts (walnuts, pecans, or almonds) to the batter for extra crunch. You can also swap the chocolate chips for white chocolate chips, peanut butter chips, or even dried fruit like cranberries or raisins.

Dump Cake Variation
For an even easier version, you can make a dump cake in the Omnia. Simply add a can of pie filling (cherry, apple, or blueberry) to the bottom of the pan. Top with a cake mix (dry, do not prepare) and drizzle with melted butter. Bake as directed for a delicious dessert with minimal effort.

Variations to Try

Double Chocolate Chip Cake
Add 1/4 cup of unsweetened cocoa powder to the dry ingredients for a rich, chocolatey cake. Use milk chocolate chips for extra sweetness.

Vanilla Bean Chocolate Chip Cake
Use vanilla bean paste instead of vanilla extract for a more intense vanilla flavor. The tiny specks of vanilla bean add a beautiful visual touch.

Chocolate Chip Coffee Cake
Add 1 teaspoon of cinnamon to the dry ingredients and sprinkle a cinnamon-sugar mixture on top before baking. The warm spice adds a cozy flavor that’s perfect for cool camping mornings.

Chocolate Chip Banana Cake
Mash 1 ripe banana and add it to the wet ingredients. The banana adds natural sweetness and extra moisture, making the cake even more tender.

Lemon Chocolate Chip Cake
Add the zest of one lemon to the batter. The bright citrus flavor balances the richness of the chocolate beautifully.
